Project Simple was ordered with 4.10 gears, which were retained. With the low 3.59:1 W5A580 First gear, the 4.10s work well with 35-inch tires. With the Rock Trac transfer case’s 4.0:1 low range, First gear low range is still a low crawling gear. Luckily, the transmission allows Second gear launches. The OE Jeep Rubicon Tru-Lok electric locker was retained. While the AEV DualSport RS suspension is designed to work with the OE track bar, we installed a JKS Mfg. adjustable track bar. A Bilstein steering stabilizer is part of the AEV suspension system, as is the high-steer drag link. The stamped steel skid plate is part of the OE Rubicon X front bumper system.
