Quick Overview

Fabtech offers a 3.5” leveling kit for off-road enthusiasts looking for enhanced capabilities that allow a set of 35” tires. Installation will give your Silverado or Sierra 2500HD and Denali a more level stance front to rear with an aggressive look. The Fabtech Uniball upper control arms will replace the factory arms to provide additional wheel travel and an extra degree of caster. Using the finest materials with .120" wall 1.50" OD 4130 Chromoly tubing, these super stout control arms are specifically designed for rugged offroad conditions to provide increased lifespan while giving you a more positive on-road feel. In place of ball joints, high quality 1" FK Stainless PTFE lined Uniball bearings are utilized. Forged torsion bar keys replace the factory keys to allow for additional ride height adjustment that works in conjunction with the new upper control arms.

A set of Fabtech Dirt Logic 2.25 shocks with external reservoir and a twin tube design will give you a good highway ride along with the ability to tackle offroad terrain. Overall this 3.5” leveling kit includes high quality components that will add both strength and reliability to your truck while giving it a commanding presence.
