The Trail Master torsion bar leveling kit is the right way to lift and adjust the ride height on 2011 Chevy/GMC 2500, 3500 HD pickups. Cranking the factory torsion keys will add spring preload to the suspension, causing a harsher ride. But the trail master keys are designed to raise the vehicle 1.5 to 2.5 inches, without additional spring preload, to maintain a smooth ride and your truck’s maximum towing capabilities.
Manufactured in the U.S.A. for both 2wd and 4wd models, the trail master leveling kit keys #CL226 are made from forged steel and include shock-mount extensions to maintain proper piston travel within the factory shocks. Easy to install, this leveling kit will allow you to run up to 33-inch diameter tires on your vehicle. Information, Performance Automotive Group, 928.636.7080, www.trailmastersuspension.com.
