TRZ Motorsports Anti-Roll Bar - Under Housing Mount - Axle Tube Mounts Included - Single Tube (1977 - 1996 Impala / Caprice - B-Body) - 322-203-UHM
Single-Tube Under-Housing Anti-Roll Bar for 1977 - 1996 Impala & Caprice (B-Body)
The TRZ Motorsports 322-203-UHM Anti-Roll Bar is a heavy-duty under-housing system designed specifically for 1977 - 1996 Impala and Caprice B-body platforms. This ARB setup eliminates chassis twist under load, allowing both rear tires to plant evenly - critical for consistent drag strip performance in large, weighty GM full-size vehicles.
This version mounts directly to the axle tubes using the included weld-on brackets. The under-housing design keeps the bar low, provides excellent packaging clearance, and delivers strong control over suspension movement without requiring a welded-in crossmember.
The single-tube bar uses robust 1.625" chrome-moly tubing paired with CNC-machined billet steel arms, making it suitable for drag builds up to roughly 1800 HP. TRZ presets the center-to-center link spacing for the B-body chassis and may reach out if measurement verification is necessary.
The kit arrives complete with billet end caps, hardware, and unwelded HD links that you can trim to your exact length requirements for perfect setup and geometry.
