Description

Skyjacker specifically engineered a progressive 2-stage dual rate long travel coil. 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 are a key link in-between the chassis and the moving parts of your suspension. Their 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. Engineered for higher speed applications, remote reservoir shocks still perform at crawl. 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). The replacement Front Adjustable Track Bar includes Skyjacker installed pressed-in HD OEM style rubber bushing and an adjustable 3/4- in. Heavy-Duty Rod End, Jam Nut and Alignment Bushings. Front and Rear Bump Stop Spacers bolt onto the axle bump pads and keep the suspension travel safely in check. Rear Extended Length Sway Bar End Links allow full articulation as the suspension drops (full droop). Rear Track Bar Lower Axle Mount Bracket mounts directly to the rear axle housing to correct the track bar angle. Dana 44 Rear Track Bar Mount Brace strengthens the factory mount that is prone to failure. The track bar bracket and brace create better handling with less side-to-side sway. Eccentric alignment cam bolts correct caster and pinion angles (front lower axle and rear upper front). Comes complete with Bushings and High-Grade Mounting Hardware.
