Cognito 3-inch Performance Leveling kit with 2.0 IFP shocks for 2020 - 2025 Silverado/Sierra 2500/3500 2WD/4WD

If you always have a tool box or several hundred pounds in the bed of your truck and the rear has squatted slightly, or you prefer a slight rear high rake along with your leveling kit, you can add the optional Cognito 1" Block and U-Bolt Kit to lift the rear. The rear shocks in this package have an extended length longer than stock to accommodate up to 1.5" of lift over stock height, while still being short enough collapsed as to not bottom out the shock if the rear is not lifted. Therefore, since using the Cognito rear shocks, adding a 1" block to this package at any time is an option.
