We've bundled everything you need in a leveling kit for your 11-19 Silverado/Sierra 2500/3500 2WD/4WD with high quality Cognito components. There is no guesswork.
The Cognito SM Series upper control arms are built with a modified ball joint angle to eliminate travel limitations of the ball joint in lifted applications. Upgrade your stock upper control arms with Cognito SM Series Control Arms for better performance, style and function.
Ample droop travel is required for good ride quality and all suspension components to last and work properly. The allowable droop travel is also improved with the design of these arms.
Cognito Torsion Bar Keys levels the front with the rear of the truck. Their forged construction makes them practically indestructible and they bolt in for easy installation. The Cognito Front Shock Spacers allow for increased ride height while retaining the stock shock. Made in the USA.

Note:
- Wheel width should be kept at 9” or less with 5”-5.75” backspacing. Tire width should be kept at 11.5” or less, and diameter kept to 33” or less, to avoid rubbing while turning. With wider than stock wheels and tires, trimming will still be required to the back bottom of the fender well area and the plastic valance under the front bumper.
