Product Details

Skyjacker suspension lift kit.

The biggest determining factors in ride quality and suspension performance are coil springs and shocks. Skyjacker specifically engineered a progressive 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 delivers a comfortable ride with the ability to flex for increased articulation. The 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. Shocks are a key link in-between the chassis and the moving parts of your suspension. 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). A heavy duty Rear Track Bar Upper Mount Bracket is included to center the axle under the vehicle properly. Front and Rear Bump Stop Spacers bolt onto the axle bump pads 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).

A suspension lift raises ride height to clear larger tires; component kits vary in what they include, so check the parts list.
