The latest addition to the 2 Wheel Drive line is the 7" Performance System for late model C1500 GM trucks. This system used the proven crossmember and steering knuckle technology found in 4WD IFS systems. The factory upper control arm remains in the stock frame pocket attaching to an extended length cast steering knuckle. An extended lenght coil spring provides increased ride height for clearance on 16x8 wheels

Use 315 / 75R16 (34 inch) tires with 16x8 wheels with 4 5/8 inch backspacing with minor trimming.
