TRZ Motorsports Anti-Roll Bar - 5" Arms - Crossmember Mount - With Twin Tube / Girth Brooks - Builders Kit - Unwelded - 203-UW5-TT
Heavy-Duty Unwelded Twin Tube Anti-Roll Bar Builder's Kit
The TRZ Motorsports 203-UW5-TT Anti-Roll Bar Kit is a premium twin-tube / Girth Brooks - style drag racing ARB system designed for racers who want maximum chassis control, straighter launches, and repeatable 60-foot times. This unwelded builder's kit lets fabricators tailor the setup exactly to their chassis while retaining all the benefits of TRZ's proven anti-roll bar engineering.
This kit includes the unwelded HD ARB link kit (1" chrome-moly tubes, rod ends, inserts, tabs, and Grade 8 hardware) plus the ultra-strong 1-5/8" inner tube paired with a 2-1/4" outer tube for the full twin-tube assembly. The result is an extremely rigid ARB with increased torsional resistance - ideal for high-horsepower drag applications.
You can build the bar up to 25" center-to-center between ARB links (shortening is allowed as needed). Choose from 5" or 6" CNC-machined billet one-piece arms, measured center of main tube to center of rod end, to suit your suspension geometry. Mounting brackets are included for crossmember installation on any 1.625" tube (crossmember not included). Twin-tube kits are not compatible with under-housing mounts due to clearance limitations.
The system also includes billet aluminum end caps with bronze bushings and grease fittings for smooth operation (bronze ID may require light sanding after welding). Once properly installed, this ARB design eliminates body roll, delivering straighter, more efficient, and more controlled launches.
