      Perfect Elevation to Clear Off-Road Bumps. The Rough Country 3.50-Inch Suspension Knuckle Lift Kit increases your truck’s ground clearance a few inches, and ups the excitement for your next off-road adventure. When adjusted for exact fitment, this kit will accommodate 33 x 11-inch tires, as well as stock or aftermarket wheels with 17-inch to 20 inches diameters. Completing the kit are lifted knuckles, durable lift blocks, and two signature accessories from Rough Country: the N2.0 performance struts and the N3 rear shocks. All of these combine to yield the perfect formula for off-road driving: stable suspension, and smooth cruising.

      Better Performance with Rough Country’s Signature Shocks and Struts. This suspension knuckle lift kit also comes with two exclusive Rough Country accessories: the N2.0 performance struts, and the N3 shock absorbers. The struts enable steady tire contact, and the shock absorbers work to dampen any disturbing vibrations. With these two accessories combined, off-road driving will be stable, smooth, and bump-free.

      Non-Intrusive and Secure Lift Knuckles. The lifted knuckles that come with Rough Country’s suspension kit are meant to support the truck’s upper arm ball joint angles, all without blocking or damaging the lower arms. This contributes to the overall lifted appearance on your truck, and grants enough ground clearance to keep its underside from harm.

      Comes With Well-Made Lift Blocks and Strut Spacers. Rounding up the whole set are a pair of fabricated lift blocks and a pair of strut spacers. These components are responsible for steadying the height of your truck, and Rough Country manufactures them to best resist wear and tear.

      Some Cutting and Grinding Needed for Proper Installation. Installation of the Rough Country 3.50-Inch Suspension Knuckle Lift Kit with Performance N2.0 Struts will be easiest if you ask for help from a pro. Note that some cutting and grinding is required for proper fitment onto your Sierra 1500. Rough Country also enjoins its buyers to get an alignment as soon as possible after lifting, so that the truck’s tires don’t wear out as quickly.

      Comes With a Lifetime Replacement Warranty. Rough Country Suspension Systems offers a lifetime replacement warranty on most suspension products. All products are warranted to be free from defects in material and craftsmanship for the life of the vehicle if utilized in accordance with the manufacturer’s instructions for installation and operation of said products.  

      Application. This Rough Country 3.50-Inch Suspension Knuckle Lift Kit with N2.0 Performance Struts fits all 4WD 2014-2018 GMC Sierra 1500 models. The kit is compatible with the vehicle’s factory cast steel control arms, and will not work with aftermarket control arms.
