Cognito 20-25 Chevy Silverado/ GMC Sierra 2500/3500HD 3in Standard SM Series Leveling Kit

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.
