built brace ties the

Control Arm Frame Braces For GM A-Body & G-Body
Control arm frame braces
are designed to strengthen
the upper and lower control
arm mounts of GM A-Body
or G-Body by joining them
together, increasing chassis rigid-
ity and preventing frame damage. Constructed from DOM steel and TIG-welded, braces are available with choice of black or red powder-coated finish. Sold per pair, complete with necessary hardware.
