TRZ Motorsports Anti-Roll Bar - Chassis Mount - 1 5/8" Crossmember Included - Single Tube (1964 - 1972 Chevelle A-Body) - 317-203
Single-Tube Chassis-Mounted Anti-Roll Bar System for 1964 - 1972 Chevelle A-Body
The TRZ Motorsports 317-203 Single-Tube Chassis-Mounted Anti-Roll Bar is engineered specifically for the 1964 - 1972 Chevrolet A-Body chassis to deliver maximum stability, improved traction, and straighter, more consistent drag strip launches. This system uses a strong 1.625" chrome-moly crossmember that welds between the frame rails or roll cage, creating an ultra-rigid mounting location for the ARB.
The single-tube design utilizes 1.625" chrome-moly tubing paired with CNC-machined billet steel arms, providing excellent torsional control for builds up to roughly 1800 HP. It's the ideal option for racers who require high rigidity without the added weight of a twin-tube (Girth Brooks) setup.
Like all TRZ Motorsports ARB systems, this kit uses pre-determined link center-to-center distances optimized for the Chevelle A-Body's geometry. TRZ may contact you for verification if needed. Every system includes the required hardware, ARB links, and precision billet end caps for smooth, reliable operation.
By eliminating chassis twist, this ARB ensures you can apply power evenly to both rear tires - crucial for predictable 60-foot times and traction consistency in high-performance drag racing environments.

Frequently Asked Questions
Why choose the single-tube ARB instead of the twin-tube option?
The single-tube 1.625" setup provides more than enough rigidity for most builds up to around 1800 HP, with less weight and simpler packaging than the twin-tube system.
What's the benefit of a chassis-mounted ARB?
A chassis mount ties directly into the frame or cage for maximum rigidity, reducing chassis twist and delivering more consistent launches and improved weight transfer.
