GM’s 2019 Sierra features an impressive all-new design that’s built from the ground up, with aggressive angles and head-turning stylings. Put the finishing touch on your truck with Rough Country’s 3.5in Upper Control Arm Suspension Lift!This perfect-height lift is a great choice for anyone who wants more than a simple level but doesn’t quite want the full height of a 6-inch option. This kit lifts and levels the front of the vehicle with the rear, offering enough increased ground clearance to run up to 295/55R20 tires with an improved, aggressive look.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. Includes a Lifetime Replacement Guarantee!
