TRZ Motorsports Anti-Roll Bar - Under Housing Mount - Axle Tube Mounts Included - Single Tube (1970 - 1981 Camaro / Firebird / 1975 - 1979 Nova) - 318-203-UHM
Single-Tube Under-Housing Anti-Roll Bar for 1970 - 1981 Camaro/Firebird & 1975 - 1979 Nova
The TRZ Motorsports 318-203-UHM Anti-Roll Bar is a proven under-housing solution for second-gen F-Body and mid-70s X-Body drag racers. This single-tube ARB eliminates chassis twist, improves traction, and ensures even power delivery to both rear tires - key for consistent 60-foot times and repeatable ETs.
This setup uses strong 1.625" chrome-moly tubing with CNC-machined billet steel arms, providing the stiffness needed for builds up to approximately 1800 HP. Because it mounts directly to the rear axle housing, this system offers clean packaging and does not require a chassis-mounted crossmember.
The kit includes weld-on axle tube brackets and unwelded HD ARB links that can be trimmed to the correct length for your specific Camaro, Firebird, or Nova. TRZ sets center-to-center link spacing based on the mount style and vehicle platform and may contact you for verification if needed.
Every TRZ ARB system includes billet end caps, link hardware, and mounting components to ensure smooth motion and reliable performance run after run.
