Elevated Power. Get the look you really want for your Silverado with the Rough Country 7-Inch Suspension Lift  Knuckle Kit. Lift your ride as high as 7 inches, and still run 35-inch tires on factory wheels. This complete suspension lift kit is designed to withstand even the most rough-and-tumble trails during your off-road adventures.

Premium N3.0 Series Shocks. These heavy-duty nitrogen-charged shocks provide the best balanced performance for off-roading and daily driving. These N3.0 shocks use a 10-stage velocity sensitive valving that has been custom-tuned specifically for this application. This results in unrivaled performance for any driving situation.

Durable Lift Blocks. Each Knuckle Kit comes with a set of heavy-duty fabricated anti-wrap lift blocks. These lift blocks provide a big boost while helping to prevent axle wrap issues from happening. On top of that, they are built stronger and possess a longer lifespan than cast blocks.

Knuckle Kit Additional Parts. This kit also includes a set of front and rear crossmembers with the “RC” logo, which gives unmatched ground clearance. It also includes upper strut spacers, differential and sway-bar drop brackets, and a differential skid plate. All of these parts feature 100% precision laser-cut materials using the latest computer-aided design process.

Professional Installation. It is advised that a certified technician perform the installation of this suspension lift kit. The whole process can be accomplished in about 8-10 hours, and may require minor cutting and drilling. Please read the installation instructions for complete information on proper tire/wheel combinations.

Three-Year Manufacturer’s Warranty and Lifetime Warranty.  All Rough Country Shocks are guaranteed a 3-Year Manufacturer’s Warranty. For all hard suspension components of this kit, a Lifetime Replacement Warranty is provided. Please visit the Rough Country website for terms and conditions.

Application. The Rough Country 7-Inch Suspension Lift  Knuckle Kit is designed to fit all 2014 to 2018 Chevrolet 4WD Silverado 1500 models with cast aluminum or stamped steel control arms. 

Application Note. You need 18-inch or larger wheels for this lift kit. Installing larger tires will require a Hypertech Speedometer Calibrator. If the tires to be used are wider than 35x12.50, offset wheels will be required and trimming may be needed. Lastly, the mass damper must be removed for vehicles equipped with one on the front differential.
