Skyjackers suspension lift kit provides improved handling and increased suspension articulation. Take your TJ to the next level of on-road drivebility with greater off-road potential. On the Wrangler TJ, coil springs and shocks are primary determining factors in ride quality and suspension performance. Skyjacker specifically engineered 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: resulting in a smoother ride. 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).
