Competition Series 4-Link Rear
Frame Package
Our Competition Series 4-Link Rear Frames are great for Pro Street or E.T. drag cars. They come completely jig welded with 4-Link mounts and upper shock cross member fully installed. For an exact fit we leave the front cross member and the rear of the frame long to allow for trimming to fit your needs. The built-in rear drive shaft safety loop has a 3¾” drop center. Our standard frame width is 24” center to center, but custom sizes are no problem and no extra cost. The package comes with QA1 coil over which contains non-adjustable shocks, springs and adjustable lower shock mounts (5½” of adjustment). Our back halves are available with 9” Ford rear axle housings. Each axle housing is jig welded to assure straightness and come with big bearing ends. Our standard housing width is 40” (45” +/- track width) but again custom widths are no problem and no extra cost.
