The updated Spider injection system has been installed that utilizes 6 separate injectors rather than poppet style. Exhaust is handled through shorty headers, to stainless exhaust with Banks Monster muffler giving the Jeep a noticeable exhaust not but far from radical. Gear shifts are handled through a GM 4l60e 4 speed automatic transmission with mild shift kit. A Novak adapter then mounts factory transfer case that has has SYE (Slip yoke Eliminator) installed. The suspension has been upgraded using Skyjacker 4.5 inch Short arm kit. This includes rear sway bar, front sway bar disconnects. The axles are Dana 35 rear limited slip and 4.56 gears, front Dana 30 has locker with 4.56 gears. This axle ratio along with Overdrive transmission works perfectly with the 33 inch BFGoodrich All Terrain Tires on Eagle Alloy Aluminum Wheels.
