Product Description

The Ridetech 11237299 Trailing Arm Chassis Braces are designed for 1964-1967 GM A-Body vehicles, reinforcing the rear suspension structure by connecting the upper trailing-arm crossmember to the lower trailing-arm frame brackets. The braces provide additional chassis strength and are particularly useful for performance and high-horsepower applications.

Each brace uses heavy-duty 1.125-inch outside-diameter tubing with a 0.219-inch wall thickness and features a double-adjustable design for precise fitment. Countersunk, angle-cut ends improve clearance and allow shorter mounting bolts, while stainless-steel adjusters and a satin-black powder-coated finish provide durability. The kit includes a matched pair of braces and mounting hardware for a clean bolt-on installation.
