On the Wrangler TJ, coil springs and shocks are primary determining factors in ride quality and suspension performance. Skyjacker specifically engineered a progressive variable rate coil spring, distinctively a 2-stage dual rate long travel coil. Spring rate progression is from a first Flex Rate to a second Ride Rate. First Flex Rate stage delivers a comfortable ride with the ability to flex/expand during full articulation as the suspension drops (full droop). This keeps the coil springs seated in the upper coil mount/bucket and the tires in contact with the terrain. Second Ride Rate stage only engages after compression past Flex Rate. Shocks key role is to optimize your suspension by keeping your tires in contact with the terrain. Skyjackers ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks deliver modern technology in the design with an innovative off-road race-inspired full-displaced valving system. From Higher Speeds to a Crawl, Skyjackers ADX 2.0 Works The external remote reservoir separates the nitrogen gas from the oil with an Internal Floating Piston (IFP). The majority of the reservoir contains pressurized nitrogen gas. The IFP prevents the gas and oil from mixing or foaming (cavitation). Front Rear Bump Stop Spacers bolt in between the upper frame and OEM bump stops. Correct bump keeps the suspension travel safely in check. Rear Track Bar Lower Axle Mount Bracket mounts directly to the rear axle housing to correct the track bar angle. This re-centers the rear axle and improves suspension handling. The track bar bracket creates better handling and a lower roll center. Lower roll center means less side-to-side sway. Eccentric alignment cam bolts correct caster and pinion angles (front lower axle and rear upper front). Works with OEM Electronic Stability Control (ESC) System. Comes complete with Bushings and High-Grade Mounting Hardware.
