Control Arm Support Braces

The increased levels of horsepower and traction achieved in modern muscle-car builds can easily cause structural damage to the chassis’ suspension mounting areas. To remedy this, Chassisworks developed a simple-to-install rear control arm support brace that reinforces the lower-control-arm mounts and upper-control-arm crossmember of 1964-72 GM A-body vehicles (Chevelle, GTO, 442).

Using the existing control-arm bolts, a folded clevis is mounted along side the upper and lower control arm mounts. The 7/8”-diameter, T-end support tube is mounted to one of the clevises on each side of the vehicle. The T-adjusters are then used to adjust the brace lengths and align them with the second clevis. After tightening all hardware, the support braces significantly strengthen the control arm mounting points, reducing unwanted fl ex, and increasing performance potential. Kits include zinc-plated support braces and T-adjusters, and Grade 8 hardware.
