This all-inclusive kit comes with several fantastic features - all at a price that'll leave plenty of room for new tires and wheels! This kit includes Rough Country's premium N3 shocks! These 10-stage variable valving, high-pressure Nitrogen charged shocks offer a fantastic blend of off-road action and smooth highway ride quality. With a durable 18mm spring-loaded piston rod and faster-cooling 54mm shock body, this shock offers up to 36kN Tensile Strength for a long lifespan of impressive vibration dampening. Features natural rubber bushings and an eye-catching metallic silver paint.

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.
