Overview

This 4.75" combo kit features our Nitrogen charged N3 Shocks offer the best in balanced performance for on and off-road use, featuring a 10-stage velocity sensitive valving custom tuned for this specific application. That means these shocks are specifically valved for use with this specific vehicle and lift combo, giving you unparalleled performance for any driving situation.

This kit also features upgraded ball joints that are easy to install and maintenance free. These POM ball joints offer a greater range of motion for more wheel articulation than standard or OE replacements and feature a Polyoxymethylene ball race with an extremely low coefficient of friction for longer life, and a larger ball diameter to improve range of motion with a maintenance free design.

Also included in this kit are a set of fabricated rear blocks. Fabricated blocks are stronger and offer a longer lifespan than cast blocks while being less susceptible to damage and the environment.
