TRZ Motorsports Modular Twin-Tube Anti Roll Bar - 6" Arms - 1 5/8" Tube (Unwelded) - 650-203UW6
Heavy-Duty Modular Twin-Tube ARB System for Maximum Launch Stability
The TRZ Motorsports Modular Twin-Tube Anti Roll Bar (Unwelded) is built for serious drag-race applications where chassis control, strength, and adjustability are absolutely critical. Featuring a unique modular design, this system allows the ARB caps to be mounted either inside or outside the arms, giving fabricators total flexibility during installation.
A precision-engineered 6-lobe spindle makes left- and right-side arm orientation simple, while the twin-tube construction - 1-1/4" 4130 chromoly inner tube paired with a 2-1/4" chromoly outer tube - delivers extreme torsional rigidity. Each side of the ARB spindle provides three weld points for superior strength under heavy load.
This system has already proven itself on high-horsepower applications, including a Promod running 3.6x 1/8-mile passes - showing its ability to manage massive torque and violent launches. With billet 7075 aluminum arms measuring 6? center-to-center and a complete HD unwelded link kit, this assembly is ready for full custom integration.
