Cognito 3-Inch Standard SM Series Leveling Kit for 20-25 Silverado/Sierra 2500/3500 2WD/4WD

Each Kit Features: Yields 3 inches of front lift Cognito SM Series Upper Control Arm Kit Torsion Bar Adjuster Key Kit Front shock spacer kit Cognito Block and U-Bolt Kit yields 1-inch of rear lift Improves vehicle appearance and reduces nose-down rake Improved ball joint angle Maintains adequate droop travel to retain ride quality 4 hour DIY install time Cognito leveling kits have ride quality in mind. In order to level your truck, droop travel must be maintained, and Cognito does that by adding droop travel that can then be converted into ride height. This ensures a minimum 3" droop travel is available to provide the best ride quality possible, leaving the rest of the ride quality result up to your choice of tires and shocks. This particular package re-uses the OEM shocks by adding spacers for the front shocks in order to provide the optimal droop stop point. Cognito SM series upper control arms are included in order to provide a corrected angle ball joint to handle the added droop. Torsion bar keys are included to provide the opportunity to set the ride height properly, and a 1" block and u-bolt kit is also included for those who have added weight permanently in the bed such as tool box and/or fuel tank and need to get the ride height back up to where it was stock. Not included in this package, but very highly recommended, is the pitman and idler arm support kit which will prevent premature wear of pitman and idler arms that arises from increased tie rod angles that is an inherent result when adding a leveling kit to an IFS truck with pitman and idler arm type steering system. Tire Fitment Fits up to a 35 x 12.5-inch tire on a 9-inch wide wheel with 5-inch backspacing Compatibility Year Make Model Sub-Model 2020-2025 GMC Sierra 3500 HD SLT 2020-2025 GMC Sierra 3500 HD SLE 2023-2025 GMC Sierra 3500 HD Pro 2024-2025 GMC Sierra 3500 HD Denali Ultimate 2020-2025 GMC Sierra 3500 HD Denali 2020-2025 GMC Sierra 3500 HD AT4 2020-2025 GMC Sierra 2500 HD SLT 2020-2025 GMC Sierra 2500 HD SLE 2023-2025 GMC Sierra 2500 HD Pro 2024-2025 GMC Sierra 2500 HD Denali Ultimate 2020-2025 GMC Sierra 2500 HD Denali 2020-2025 GMC Sierra 2500 HD AT4 2020-2025 Chevrolet Silverado 3500 HD WT 2020-2025 Chevrolet Silverado 3500 HD LTZ 2020-2025 Chevrolet Silverado 3500 HD LT 2020-2025 Chevrolet Silverado 3500 HD High Country 2020-2025 Chevrolet Silverado 3500 HD Base 2020-2025 Chevrolet Silverado 2500 HD WT 2020-2025 Chevrolet Silverado 2500 HD LTZ 2020-2025 Chevrolet Silverado 2500 HD LT 2020-2025 Chevrolet Silverado 2500 HD High Country 2020-2025 Chevrolet Silverado 2500 HD Custom 2020-2022 GMC Sierra 3500 HD Base 2020-2022 GMC Sierra 2500 HD Base 2020 GMC Sierra 3500 HD 2020 GMC Sierra 2500 HD Instructions Installation Instructions #7037 (Size: 607.2 KB) Installation Instructions #7267 (Size: 1.1 MB) Installation Instructions #8150 (Size: 276.9 KB)
