Details

We have bundled everything you need in a leveling kit for your Silverado/Sierra 2500/3500 2WD/4WD with high quality Cognito components. There is no guesswork.

The Cognito SM Series Upper Control Arms provide ample droop travel that is required for optimal ride quality and all suspension components to last and work properly. Cognito Torsion Bar Keys allows for increased front ride height. Their forged construction makes them practically indestructible and they bolt in for easy installation.

The Cognito 1-inch Block and U-Bolt Kit includes 1-inch tall powder coated semi-gloss black cast steel blocks and heavy-duty zinc plated U-bolts.

The Fox 2.0 Performance Series shocks contain the latest in shock technology to transform the performance of your truck. The IFP eliminates oil aeration allowing maximum performance from the factory-tuned, precision valving. They are easy to install and provide a comfortable on-road ride and predictable off-road handling in even the toughest conditions.
