Rough Country's 3.5in Bolt-On Kit offers easy installation and aggressive good looks at an incredible value. Take your truck to new heights with this excellent option for GM HD Models.
This kit features a set of high-quality, tubular Upper Control Arms with a reinforced gusset plate and Clevite rubber bushings for enhanced durability. These arms are designed to promote a factory-like geometry by keeping the ball joint at optimum angles after lifting. This design allows for an improved, full range of motion from the ball-joint, with less stress, wear and tear.
This kit also features a set of durable, forged torsion bar keys, offering uncompromising strength and rigidity over factory keys. A set of front and rear N3 Nitrogen-charged shocks are also included in the kit, giving your truck incredible ride-quality both on and off-road. Once installed, this kit gives your truck plenty of ride height for up to 33in tires while offering a clean, level look from front to rear.
This all-inclusive kit comes with everything you need, and installation is a piece of cake compared to other kits on the market! Featuring a 100% bolt-on installation process that requires zero cutting or drilling, this kit can be installed using common tools in a home garage, and allows the truck to be returned to stock at any time if so desired. Best of all this kit features Rough Country’s Lifetime Replacement Warranty.
