TRZ Motorsports Anti-Roll Bar - Chassis Mount - 1 5/8" Crossmember Included - Single Tube (1978 - 1988 Impala / Caprice - G-Body) - 319-203
Single-Tube Chassis-Mounted Anti-Roll Bar for 1978 - 1988 Impala & Caprice (G-Body)
The TRZ Motorsports 319-203 Single-Tube Chassis-Mounted Anti-Roll Bar is engineered for 1978 - 1988 Impala and Caprice G-body platforms, delivering the traction control and chassis stability needed for serious drag applications. This ARB eliminates chassis twist during launch, ensuring both rear tires plant evenly for improved 60-ft times and better down-track consistency.
The system includes a heavy-duty 1.625" chrome-moly crossmember that welds between the frame rails or integrates with the roll cage. The anti-roll bar mounts directly to this structure, maximizing rigidity and stabilizing the vehicle under heavy acceleration - especially important on long-wheelbase, heavier GM sedans.
The standard single-tube ARB uses strong 1.625" chrome-moly tubing with CNC-machined billet steel arms, providing torsional strength suitable for drag builds up to approximately 1800 HP. TRZ presets the link center-to-center distances for G-body geometry and may contact you if verification is required.
Each kit arrives complete with billet end caps, hardware, and adjustable ARB links for a reliable, track-proven setup.
