Superlift 2011-2016 GM 2500HD 2.5" Suspension Lift # 40025
Superlift Part # 40025 - Made in the USA!
The Torsion bar suspension used on the 2011+ Chevrolet Silverado and GMC Sierra 2500HD / 3500 trucks inherently have some amount of height adjustability built right into their design. The torsion bar keys have a Hex (six-sided) hole cut into them that mates to the end of the torsion bar. As the torsion key is rotated they in turn rotate the torsion bar which rotates the lower control arm which lifts the truck. Superlift's Level-It Keys have the Hex cut in a slightly different relation to the key, the Hex cutout is rotated slightly and that allows you to increase the bar rotation and the lift without maxing out the factory adjustment bolt.
