Upgrade your weak OEM coils to an optimal 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. Skyjacker's ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks deliver modern technology with an innovative off-road race-inspired full-displaced valving system. Skyjacker's ADX 2.0 work from high speeds to a crawl. The external remote reservoir separates the nitrogen gas from the oil with an Internal Floating Piston [IFP]. The IFP prevents the gas and oil from mixing or foaming [cavitation]. Longer replacement Front Lower Control Link Arms have pressed-in HD OEM style vulcanized rubber bushings at each end and correct caster angle. Front Adjustable Track Bar features a 3/4 in. Teflon[R] self-sealing self-lubricating rod end and mounting bracket w/hardware. Incl. replacement Steering Stabilizer. Front Sway Bar End Links allow full articulation at full droop. Front Bump Stop Spacers bolt onto axle bump pads to keep the suspension travel safely in check. Skyjacker[R] Softride[R] leaf springs taper over the entire length of the leaf creating more flex at the leaf ends. This tapering distributes loads more evenly over a greater area and reduces the tendency for one leaf to dig into the leaf above it. Teflon[R] wear pads between leafs and bolt style spring clips prevent binding and eliminate friction. Longer replacement rear leaf spring shackles increase the performance of the leaf springs by giving them more room to travel and flex.
