Dependable Off Road Sway Bar Disconnects

These were the 1st add on to my jeep. They are 3 part disconnects unlike the popular 2 part models from JKS. I selected a 3 part thinking that if I ever changed my lift height that I could replace the center section and save some time and money. Let me say this, if you don't have a set of disconnects then you are really missing out. They make a huge difference in performance.

JKS Spring Mount Skid Plates

These skid plates replace the standard spring mounting plate on the bottom of each leaf spring. They are solid steel and have a removable shock mount on the front brackets. Mounting a set of these on the bottom of the jeep allows you to trim the U-Bolts flush with the skid plate. It will prevent you from getting hung up on the downward pointing bolts. In addition if you happen to peel off a lower sway bar mount on a large rock then you can replace it without removing the U-Bolts.

I tried a really rocky trail this weekend. The JKS skid plates proved their worth. I have one small scratch on a corner after smacking them off several large rocks. Just incredible !

Explorer Pro-Comp 2.5" Suspension Lift

When I purchased my jeep it had dealer installed 30" tires. They were fine for on road driving but off road they  hit the wheel flares pretty bad. So I decided I needed to investigate a lift for more clearance and perhaps increased articulation. I decided on a 2.5" lift kit. This would allow me to clear 31" tires and offer more load capacity and the potential for better articulation. I installed the lift kit in a single afternoon with help from a friend. While this job does not require 2 people it sure makes it easier. The kit was complete with easy to follow directions. It included all necessary springs, track bar relocation brackets, rear shims, and a transfer case lowering kit. While the transfer case lowering kit may have not been required for a 2.5" lift I installed it anyway to eliminate the possibility of rear drive line vibration. After the lift kit was installed it was off to the shop to have the jeep aligned. The end result after 2.5 years of driving is that the Jeep works fantastic off road, but it has a very very stiff ride on the road. It rides much better fully loaded than with just a single driver.

After replacing the shocks and putting a new bumper and winch on the vehicle the ride has gone from stiff to smooth. The transformation is incredible. The good news is that the springs have handled the increased weight on the front end without drooping.

11/23/98 I just got finished replacing the Pro-Comp suspension lift with one from ARB. The rear Pro-Comp springs had started to sag very badly and no longer were functional off road. I got about 4.5 years of life out of the springs.

Difficulty : 5
Value : 3 ( they should have lasted longer)

Old Man Emu 2.5" suspension

After my Explorer Pro-Comp Springs died I needed a set of replacement springs. I decided on the Old Man Emu springs from ARB. They installed painlessly and restored my jeep to the proper ride height. I selected the heavy duty rear springs so my jeep sits slightly rear high. The front springs seem to be carrying the weight of the winch and ARB bumper well. The springs have bolt style clamps and are fully greasable. After the installation I noticed that the right quality felt like I was running fully broken in springs not a fresh set. The highway ride is very smooth and the springs appear to be a great match with the Rancho 9000 shocks. The ride off road is also very good. The springs really flex and to my great delight they make much less noise than my old set.

3/20/99 I just finished adding a extra leaf to the front spring pack to increase the ride height. I got about 1" of lift back and it has not affected ride quality.

Difficulty : 5
Value : 6 (time will tell)

Explorer Pro-Comp ES-3000 Shocks

These shocks came with the lift kit. I have found through extended research that these shocks are super super stiff. I am currently in the process of replacing them.

I replaced them with Rancho RS9000 Shocks. On a setting of 1 the Rancho's give a superior ride. Off road you can feel the tires hugging the ground. Big improvement in ride quality.

Currie Enterprises Shackles

In an effort to increase the strength of the suspension and smooth out the ride I purchased a new set of Currie Enterprises Shackles. Installation took an afternoon and required nothing but simple hand tools and a jack. After installing and greasing the shackles I noticed an immediate improvement in the ride. It was much smoother on the street. During the 1st off road trip with them I also noticed a smoother ride and the squeak from the leaf spring bushings was gone.

Con-Ferr Front Skid Plate

After taking a few trips off road in my stock jeep I noticed how vulnerable the steering components are. I had been lucky and sustained no damage to them but decided I needed to find some additional protection for them. I found just the thing in the form of a front end skid plate from Con-Ferr. This skid plate is designed to attach to the factory bumper and requires drilling 3 holes in the front of the bumper. It bolts to the frame using existing holes and heavy duty hardware. The skid plate is very solid has endured some rather severe abuse. On a trip to Missouri I hit a deer carcass on the freeway and sustained no damage to the front end at all. The skid plate took the hit with no damage at all.

NOTE: this skid plate can be adapted to work with the ARB bumper. Provides great front end coverage.

Rubicon Express Slip Yoke Eliminator

After whacking my transfer case skid plate on almost every rock on the trail I decided to remove the lowering kit that I had installed as part of my suspension lift. I purchased the Rubicon Express slip yoke eliminator kit to allow me to do this. The kit went in pretty easy, the real scary part was cutting the existing output shaft. I did that using an abrasive blade on a circular saw. After installation I raised the transfer case and have no problems with driveline vibrations.

Rubicon Express Adjustable Track Barone.jpg (41821 bytes)

Well after installing the lift and associated brackets a few years back I noticed that the track bar relocation bracket would not stay tight. Rather than purchase another bracket I decided to get an adjustable track bar. This would eliminate the bracket and allow for more articulation when on the trail. When installing the Rubicon Express track bar you will need a 9/16" drill bit to enlarge the mounting hole on the axle. This is not required if you have a dropped pitman arm. The Rubicon Express unit uses a bushing on one end and a heim joint on the other end, it has a single bolt that allows the track bar to extend when its loose.. Mounting this bar and restoring the factory geometry to the steering has improved my on road ride. The heim joint allows for much better articulation off road even when the track bar retaining bolt is tight.

K&N Air Filter

This one was a no brainier. I swapped out the standard factory air filter for the K&N soon after purchasing the jeep. It was a perfect drop in kit. After 50,000 miles I decided to clean the air filter and purchased a cleaning kit from NAPA. The cleaning process took the better part of one afternoon and the filter was as good as new. After installing the filter I did not notice any additional improvements in performance. However once I removed the air restrictor from the factory air box I noticed better passing performance on the freeway and better average MPG at the pump.

MSD 6A

I have had a MSD 6A box for a considerable period of time. It used to be installed on my old Toyota truck. It worked great there and when I sold it I decided to keep it just in case I need it. After owning the jeep for a while I decided to try installing it. It was a drop in installation requiring no extra parts or transformers like the Toyota did. However it does require either cutting some factory wiring or locating the factory style coil wire connectors. I opted to make my own connectors so that if the MSD failed I could revert back to the factory setup. I also installed the Jacobs Ultra Coil. This coil has a variable magnetic core that allows it to change output based on demand. After installation I noticed right away that low end performance had greatly improved as well as high end performance, the midrange remained the same. I was able to put the Jeep in 1st gear and idle up hills without using the gas and with no knocking and pinging. I also noticed an improvement in MPG when it was time to fill up.

11/1/98  Somehow I managed to break my MSD-6A. I have been using this unit for about 6 years with no problems. I took this opportunity to change the unit to a MSD-6AL. The new unit has vibration mounts and extra internal coatings for increased water and vibration resistance.

Difficulty : 4
Value : 7

MSD HVC-Blaster Coil

When I installed my new MSD computer I also took the opportunity to install a new coil I chose the MSD HVC-Blaster coil. This is a new design coil from MSD that delivers high voltage and high current. It is a rather large and heavy unit and uses 4 rubber mounts to provide vibration resistance. So far results have been very positive both on and off road.

Difficulty : 3
Value : 7

Jacobs Ultra Coil

I purchased the Jacobs Ultra Coil to go with my original Jacobs ignition computer. The coil features a varible magnetic core that allows the output to change based on demand. This coil was an improvment over stock, however it did not appear to offer quite the punch I was looking for.

Accel 8.8 Wires

Well after installing the MSD 6A those cheesy factory wires had to go. I went down to the store and grabbed a set of Accel 8.8 wires. Since there was not a set made for the Jeep I got the custom fit set for a V8. That would give me more than enough length and some spare parts as well. The 8.8 wires are very thick and have a bright yellow jacket. They also have nice thick boots on both ends. I also chose to replace the factory distributor cap with one from NAPA. While it is a good cap the vent line on it will need to be relocated to someplace higher. When changing spark plug wires and such don't forget to use dielectric grease. It will help keep a good connection and make the boots that much easier to remove when its time to change the plugs.

10/15/98 After using these wires for several months I noticed that the RFI increased gradually as time passed. Eventually it got so bad that I could not use the CB. I replaced them with Magnacore wires and the problem went away.

Difficulty : 3 (you gotta make each wire)
Value : 2

Magnacore Wires

After finding that my Accel 8.8 wires were putting out too much RFI I searched the web for a better supression wire. I came up with Magnacore. They even make a special wire for vehicles with CB type radios. I picked up a set of their 8mm wires and an extra length 10mm coil wire. After installation they appear to have fixed my radio problem. Everyone can hear me loud and clear now. The wires appear like they are built to last. They have a nice heavy red outer jacket and good quality ends.

Torque Master Spark Plugs

When you overhaul the ignition system in your Jeep never overlook the spark plugs. I have tried almost all of the "improved" spark plugs over the years and have found a few things out. When you use an aftermarket computer like MSD that increases spark power it tends to chew up the plugs. Plugs like split fire are unnecessary and sometimes detrimental to performance with a high output ignition system. Most of the aftermarket computer makers will tell you not to use them. I had settled on Champion Truck Plugs as the best conventional plug that I could get. They lasted quite a while and worked well. Then I found out about Torque Master spark plugs. They use a completely different design. They come in 2 gap configurations, a .090 for standard ignitions and a .120 for high output ignitions. After talking with one of their techs I opted for the .120. Installation was a snap and because of the design no indexing was necessary (at least as far as I can tell). After installation and a few tanks later I noticed improved acceleration and improved MPG. Overall results including the air filter, exhaust, MSD, Accel wires and Jacobs coil have improved me from about 230 miles per tank to about 270 miles per tank.

Dunlop Mud Rover Tires

Well after 50,000 miles it was time for new tires. This time instead of taking the cheapo route I decided to invest in a set of quality tires to see if there is any difference. My previous tires were all terrain cheapo's. They did not balance well and needed replacement after only 16,000 miles. I selected the Mud Rovers and had the local tire shop pop a set on for me. I noticed right away that the tires balanced well, only requiring a few small weights on each size. With the aggressive tread I expected a loud ride but was surprised by a quiet hum on the highway. Off road the tires work great. The grab and bite and it is difficult to spin the tires on a dry dirt road. There is a world of difference in the mud. Just keep 'em spinning and they keep digging.

After several trail rides I have noticed that these tires have incredible grip on rocks, mud and loose dirt. They have allowed me to traverse all kinds of terrain with little or no wheel spin while my friends that have mild all terrain tires have to spin them a bit to make it through.

Difficulty : 1 (kinda hard to write that check)

Quick Air 2 Compressor

It never fails, you are out in the middle of nowhere and you get a flat. Well instead of purchasing another one of those cheap $29 air compressors that run from the lighter socket I purchased the Quick Air 2 hard mount. I mounted it inside the engine compartment on the drivers side. The wiring was very simple and the supplied wire was more than long enough to reach across the engine compartment. I also purchased a 25' flexible hose with quick release fitting. I have used this several times after leaving the trail to air my tires back up. I have also used it to fill up a tire on a Ford Explorer that was completely flat. All I can say is wow. This compressor is really fast. The next step is to add an onboard storage tank for air tools.

I had a problem with the compressor this past weekend. The end of the connecting rod came off its bearing. It was an easy 15 minute fix back at my apartment. Time will tell if it happens again.

Hi Lift Jack

Again here is another no brainier. After lifting the jeep the standard factory jack would not cut it. So I headed on over to Pep Boys and picked up the Hi Lift Jack. It has been a dream to work with. When I take a trip off road I just toss it in the back and off we go. If you take a look at the trip 2 photos you can see the jack in action as a winch. So far it has not let me down

Tuffy Storage Trunksix.jpg (49450 bytes)

If you own a jeep this one is a must. After being ripped off 2 or three times everyone gets a little smarter. My jeep was getting broken into even though there was nothing in it. So I installed the Tuffy storage trunk one afternoon. The installation process requires drilling 4 holes and is much easier with 2 sets of hands. After installation I can still fold up the rear seat and also put the top down. I have been able to put a huge amount of stuff in the trunk and so far nothing has been stolen. Don't confuse this with other products that are made of wood or plastic. This one is all STEEL !

Performance Friction Brake Pads

Well after changing my brake pads I noticed that the Pep Boys pads tended to squeak and had increased my stopping distance. I went out and got a set of Performance Friction carbon metallic pads. Huge difference. You can feel the pads grab the rotors with very little pedal effort. They even work well when wet and covered in mud. The best part is no more noise !

Rancho RS9000 Shocks

I purchased a set of RS9000 front shocks. They were easy to install (as most shocks are), the total install time was about 15 minutes. I am currently testing the different settings to see what effect they have on ride quality. My general impression is that on a setting of 1 or 2 they offer a much improved ride over my previous shocks. You can feel the tires following the terrain where the old shocks made the tires hop. I have been off road twice since installing the shocks. My initial impressions are very good. Its nice being able to turn up the shocks as the terrain gets worse.

I recently added the matching rear shocks. My initial impressions were right on. With all 4 shocks the ride matches the quality of a TJ. Its really smooth on the pavement and just fantastic off road. The ability to set the shocks to match the terrain is just incredible.

Warrior Diamond Plate Cornersfive.jpg (68606 bytes)

I just finished installing a set of diamond plate corners on my jeep. I did this to offer some additional protection against the scratches and dents that my rear corners were picking up. I chose the Warrior products plates with the holes pre cut. The passenger side plate did not have the holes drilled for the the tailgate stop, and the drivers side had the holes for the gas filler drilled in the wrong location. This increased the difficulty due to the extra drilling that was required. The corners look good and I think they offer a substantial improvement in protection.

Difficulty : 5

Jacobs Ignition Computer

I purchased a Jacobs mileage master computer with the ultra coil in the hopes of increasing engine performance. To make a long story short the computer has failed twice and never delivered the performance advertised when it was working. The installation instructions were very poor and in some cases were directly contradicted by Jacobs tech support. The ultra coil is worth the money and has given me no problems, it works well when driven my my MSD.

ARB Bumperseven.jpg (57344 bytes)

I purchased this bumper in an effort to protect my front end. I recently dented up my drivers side fender on a tree that just pushed the factory bumper out of the way. This bumper offers major front end protection and has the advantage of a built in winch mount. The installation is very simple and takes longer to remove the old bumper than to install the new one. All of the holes lined up and required no drilling. The winch mount plate requires drilling 2 holes and that's it. Total installation time was about 2.5 hours.

After taking the new bumper out on the trail I have noticed no scratches or dents after a few encounters with rocks, dirt and a few trees.

Difficulty : 2

Warn XD9000i

I picked up the Warn XD9000i at the same time as the ARB bumper. I also purchased the winch accessory kit. The winch installation was simple and straight forward. It was made easier because of the ARB bumpers winch mount. Cable routing was very simple and the total install time was about 1 hour. This job is much easier if you have 2 sets of hands. The winch is very heavy !

This past weekend I used the winch to pull me up a very steep and rocky section of trail with no problems. Then I turned around and winched 3 other jeeps up the trail. The winch never even got hot and never stalled. I had some initial concerns after reading some information put out by MileMarker, but I never had any of the problems they described.

Difficulty : 3
Value : 7

TFX Cat Back Exhaust

My exhaust had seen one to many rocky trails so I purchased the TFX cat back exhaust system. I also purchased a new free flowing catalytic converter at the same time. The internals of my old converter were just banging around and it needed replacement. The whole system bolted up with out too many problems. The only real complaint that I have is the flared tip. This a jeep not some stupid honda or something. However the problem with the tip seems to have corrected itself after one trip off road. A good solid smack from a rock has reshaped it.

Turbo City Adjustable Timing Sensor

In an attempt to maximize the benifits of all of the other engine mods that I had done I purchased and installed the Turbo City Adjustible Timing Sensor. This is a modified crank shaft position sensor that allows the timing of the engine to be changed. I advanced my timing by about 4 degrees. This was a very simple install and in conjunction with the other mods has provided me with more power, especially on the freeway.

Difficulty : 2
Value : 7

Turbo City Adjustable MAP Sensor

I purchased the Turbo City MAP modifier at the same time as the timing sensor. This unit plugs into the existing MAP sensor and allows you to modify the fuel air mixture. A multimeter is required for installation and adjustment. I set the initial values following the directions, however after running the unit for about 2 weeks I decreased the settings because the engine was running a bit rich. This unit produces a very noticible change to engine performance. Under hard acceleration my engine had a flat spot for about 5-600 RPM around 2500 RPM. This unit removed the flat spot and now the engine pulls smoothly from idle to redline.

Difficulty : 3
Value : 7

Turbo City Oil Pan Skid Plate

I purchased this cause I started to notice a few scratches on the bottom of my oil pan. The installation is brain dead simple and takes about 10 minutes. The skid plate is well constructed and has survived several good hits from rocks.

Odyssey Battery

Knowing that I would need additional power for winching I decided to upgrade my battery. I was going from one of the 900 CCA Champion truck units and wanted something better. I looked at the Optima battery initially but decided to go with the Odyssey battery. It uses a dry cell construction so it will not leak like the Optima. However it has a higher duty cycle rating for total discharges. It will withstand 400 total discharge cycles. The Optima is not even close in this regard. The Odyssey battery is very small and light for its power output. I think I'm going to be able to mount 2 in the standard battery tray.

After using this battery on the trail I have nothing but positive things to say. It withstood the winch load to get 4 jeeps past a really tough spot on the trail. It never once faltered and the recovery time was amazing. It was fully charged before we left the trail that evening.
