1988-08 Chevy/GMC 2WD/4WD 2" Torsion Bar Keys Installation Instructions

Before beginning the installation, thoroughly & completely read these instructions, the enclosed driver’s WARNING NOTICE & affix the WARNING decal in the passenger compartment in clear view of all occupants. Please refer to the Parts List to insure that all parts & hardware are received prior to the disassembly of the vehicle.

Make sure you park the vehicle on a level concrete or asphalt surface. Many times a vehicle is not level (side-to-side) from the factory & is usually not noticed until a lift kit has been installed which makes the difference more visible. Using a measuring tape, measure the front & rear (both sides) from the ground up to the center of the fender opening above the axle. Record this information below for future reference.

IMPoRTANT: The net amount of ride height increase depends upon the age & use of the vehicle, wheel offset, & numerous other factors. Stated torsion bar ride height increases are based upon the factory specifications. If the torsion bars were “cranked up” at some point in the past, expect a corresponding reduction in overall height increase with the new torsion keys.

NoTe: The torsion bars, like any other spring, are subject to fatigue & sagging over time. Also, torsion bars have different ratings depending on how the vehicle was equipped from the factory. In some cases, installing heavier rated bars (which can be purchased from a Chevy / GMC dealer) may be the only solution to regaining ride height lost from adding heavy aftermarket accessories, such as a winch bumper or snow plow.
