1999 Wrangler Sport, 4.0L Engine, with 5 Speed Transmission. Much has been done to maximize the off-road functionality of this Jeep. It is custom-built for daily driving and for showing off, off-road!
Engine Modifications: Very few engine modifications have been made, because playing with the motor really can decrease off-road functionality. The stock engine has more than enough torque and throttle response for off-road use. I did however put a Banks Exhaust Header on, and before installing it, I had it ceramic coated, inside and out, for extreme heat conditions. This keeps the intake manifold as cool as possible and significantly increases the Jeep's ability to run well when the terrain requires a slow and steady speed. It also has a K&N Air Filter. That's about all I've done to the engine. Interior-wise: I've removed the carpet and installed a custom-fit, second switch panel where the factory ashtray went. This panel holds the ARB Locker switches and the road-light switch, with two blanks left. I planned on using the blanks for brake-line locks, but didn't get around to installing them. The factory top didn't fare too well after a tree mangled one of the bars that held it in place, so it has been replaced with a Safari Top Duster Cover, and a Wind Jammer. This combination will keep you warm and mostly dry in the rain. The Drive Train: This is where I could go on forever and easily forget something. My first upgrade was the ARB lockers, front and rear, matched to the 4.56 gears and alloy axles. Wow, what an improvement to off-road functionality! However, the strength (or lack thereof) of the factory Dana 35 was shown. After breaking three axles, I replaced the rear axle with a Ford 9-inch, 35 spline-axle (F-350 Super-Duty), custom-built by Sun Ray Engineering out of the Dallas area. The front and rear drive shafts were built by Tom Woods Drive Shafts (4xshaft.com). They come with a lifetime warranty and a
