TRZ Motorsports Anti-Roll Bar - Under Housing Mount - Axle Tube Mounts Included - Single Tube (1964 - 1972 Chevelle A-Body) - 317-203-UHM
Single-Tube Under-Housing Anti-Roll Bar for 1964 - 1972 Chevelle A-Body
The TRZ Motorsports 317-203-UHM Anti-Roll Bar is designed for Chevelle A-Body racers who want a clean, low-profile under-housing installation that provides excellent launch stability and eliminates chassis twist. This single-tube ARB mounts directly to the rear axle housing using the included axle tube brackets and is ideal for high-performance drag racing applications up to roughly 1800 HP.
The single-tube ARB uses 1.625" chrome-moly tubing paired with CNC-machined billet steel arms to deliver strong, dependable torsional control. This configuration provides the rigidity needed for most competitive builds while being lighter and easier to package than twin-tube "Girth Brooks" systems.
This under-housing kit includes weld-on axle tube brackets and unwelded HD ARB links that you can trim to the perfect length for your application. TRZ uses pre-determined center-to-center link distances based on the A-Body chassis and mount style, and may contact you for verification if needed.
Like all TRZ anti-roll bar systems, the kit includes billet end caps, ARB links, and full mounting hardware. Once installed, the bar keeps the chassis square under power and ensures both rear tires plant evenly - dramatically improving traction and 60-foot consistency.
