The factory GM version of Independent Front Suspension (IFS) consists of springs, in the form of torsion bars, upper / lower control arms and a differential with Constant Velocity (CV) axle shafts. When lifting the GM IFS, the primary factors that ensure good vehicle driveability traits and component service life are: steering geometry, suspension travel control and CV axle operating angles. This statement holds true regardless of how much the vehicle is lifted, whether it is 2”, 7.5” or anything in between. Superlift offers numerous lift heights and methods for these very popular vehicles. Step one in your decision making process is determining what size tire you wish to run (refer to chart below). Secondly, consider what the vehicle will be used for; will it be basic commuting or performance driving? For most lift heights, Superlift offers different products with corresponding levels of performance and cost.

NOTE: General Motors ½-ton vehicles with IFS, manufactured from 1988-to-present, have relatively light-duty ball joints and steering linkage. We do not recommend using tires larger than 37” in diameter.
