TRZ Motorsports Anti-Roll Bar - Chassis Mount - 1 5/8" Crossmember Included - Twin Tube (1964 - 1972 Chevelle A-Body) - 317-203-TT
Twin-Tube Chassis-Mounted Anti-Roll Bar for 1964 - 1972 Chevelle A-Body
The TRZ Motorsports 317-203-TT Anti-Roll Bar is the top-tier option for serious Chevelle A-Body drag racers who need the strongest possible chassis control. This chassis-mounted "Girth Brooks" Twin Tube ARB uses a 1.625" inner chrome-moly tube paired with a massive 2.25" outer chrome-moly tube, creating an ultra-rigid assembly designed for extreme horsepower levels and maximum torsional stability.
This version includes a chrome-moly 1.625" crossmember that welds securely between the frame rails or the roll cage. The ARB mounts directly to this structure, offering unmatched rigidity and minimizing chassis twist during aggressive launches.
Like all TRZ systems, this kit uses pre-determined center-to-center link spacing optimized for the 1964 - 1972 Chevelle A-Body platform. TRZ may contact you if verification is needed. Every kit includes billet end caps, ARB links, and the required mounting hardware for a complete installation.
The result is a chassis that stays square under power - allowing you to deliver power evenly to both rear tires, improve 60-foot consistency, and maintain better traction at every launch.

Frequently Asked Questions
Who should choose the Twin Tube "Girth Brooks" ARB?
This version is ideal for extreme horsepower cars or radial-style drag racing where maximum torsional rigidity is required to keep the chassis square under load.
Why use a chassis-mounted anti-roll bar?
A chassis-mounted ARB ties into the frame or roll cage for the highest possible rigidity, improving launch consistency and eliminating chassis twist far more effectively than under-housing systems.
