Skyjacker 21-22 Jeep Wrangler Unlimited Rubicon 392 Long Travel 2.5in Coil System

Jeep(R) answered you power-hungry adventurers request for power and off-road performance with the Wrangler Rubicon 392. The heavy 6.4L HEMI(R) V8 engine packs a powerful punch. The suspension and chassis upgraded design lends to controlled on-pavement handling and unrelenting off-road dexterity. Taller, more aggressive 37- in. tires and more ground clearance will only make it better.On this application, the biggest determining factors in ride quality and suspension performance are shocks and coil springs. You can keep your current Jeep tuned factory performance shocks yet upgrade the OEM coils to an optimum performance option.Skyjacker specifically engineered a progressive variable rate coil spring, distinctively a 2-stage dual rate long travel coil. Spring rate progression is from a 1st Flex Rate to a 2nd Ride Rate. The 1st Flex Rate stage of the coil spring delivers a comfortable ride with the ability to flex for increased articulation. The coil spring's flex rate expands 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. The 2nd Ride Rate stage only engages after compression past the flex rate. Engineered to coordinate with the Rubicon 392's distinctive suspension handling characteristics, the rear coils are side specific and designed to handle impact absorption in the toughest off-road conditions. Front and Rear Shock Extension Relocation Brackets reposition your specifically tuned factory performance shocks. Front and Rear Bump Stop Spacers bolt onto the axle bump pad and keep the suspension travel safely in check. Front and Rear Extended Length Sway Bar End Links allow full articulation as the suspension drops (full droop). These sway bar end links include Skyjacker installed pressed-in HD OEM style rubber bushings.Proper suspension geometry ensures the Electronic Stability Control (ESC) system functions within factory parameters.

Reference Information

Suspension Lift Kit, 2.5 in. Front, 2.5 in. Rear, 4-Door, Jeep, JL, Rubicon 392, Kit

Skyjacker Long Travel lift kits are available in different lift heights for different 4WD models. They feature dual-rate long travel coil springs, providing the best of both driving worlds, on-road and off-road. The first spring rate delivers exceptional on-road ride and the coils will expand while off-roading during extreme articulation, as the suspension droops, to keep the tires in contact with the ground much longer than linear rate or single rate coil springs. This results in a smoother and more controlled ride, while keeping the coil in the coil bucket at full droop. The second rate lower coils only engage after compression past the first rate, and this allows consistent control and stability when heavy off-road suspension movement is required.
