TRZ Motorsports Anti-Roll Bar - Chassis Mount - 1 5/8" Crossmember Included - Twin Tube (1977 - 1996 Impala / Caprice - B-Body) - 322-203-TT
Twin-Tube Chassis-Mounted Anti-Roll Bar for 1977 - 1996 Impala & Caprice (B-Body)
The TRZ Motorsports 322-203-TT Anti-Roll Bar is the extreme-duty Twin Tube "Girth Brooks" version designed for 1977 - 1996 Impala and Caprice B-body platforms. Built for serious drag racers, this ARB delivers unmatched torsional rigidity, eliminates chassis twist, and ensures even power transfer to the rear tires for harder, straighter launches every time.
This chassis-mounted system includes a 1.625" chrome-moly crossmember that welds between the frame rails or ties into the roll cage. By mounting the ARB directly to this rigid crossmember, the system stabilizes the heavy B-body chassis under high horsepower loads.
The Twin Tube bar uses a 1.625" chrome-moly inner tube encased by a 2.25" chrome-moly outer tube, paired with CNC-machined billet steel arms. This design delivers the highest torsional strength TRZ offers - perfect for big-power full-size GM builds.
TRZ presets the center-to-center link distances for correct B-body geometry and may contact you for confirmation if needed. The kit includes billet end caps, ARB links, and all required hardware for full installation.
For high-horsepower Impala and Caprice builds, the Twin Tube ARB provides the chassis stiffness required for maximum traction and consistent ETs.
