# Cognito 01-13 Chevy/GMC Silverado/Sierra 2500/3500 HD 2WD/4WD Torsion Bar Keys

Torsion bar keys are used to set the ride height of the front of the truck and are commonly used in leveling kits, and it is important to set the height appropriately as to leave ample suspension droop travel to maintain a good ride quality.There are several different torsion bar spring rates that GM made and put in these trucks, the rate depending on the model and features of the truck. Some trucks that have a higher spring rate may not need aftermarket torsion bar adjuster keys to obtain the maximum recommended ride height.This kit is Only used in leveling kit applications as well as lifted applications when the higher setting of that particular lift kit range is desired like taking a 4 Inch Cognito lift kit to the 6 Inch setting.
