GMs 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" Forged Aluminum 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" 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. The most durable Upper Control Arm to date! Rough Country's Forged Upper Control Arms feature a solid, 1-piece design made of forged aluminum for superior strength and durability. This forged design outperforms all other types of arm construction, with no welding weak spots that could bend or break. 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!
