TRZ Motorsports Modular Twin-Tube Anti Roll Bar - 7" Arms - Flat No Radius (Unwelded) - 650-203UW7F
Flat-Tab Modular Twin-Tube ARB with 7" Billet Arms for Maximum Tuning Range
The TRZ Motorsports Modular Twin-Tube Anti Roll Bar - 7" Arms - Flat No Radius (Unwelded) is the ideal choice for fabricators needing maximum adjustability with a flat mounting-tab design. This ARB allows you to mount the billet end caps inside or outside the arms, giving you complete freedom to package the system exactly how your chassis demands.
Featuring TRZ's precision-engineered 6-lobe spindle interface, the arms can be oriented perfectly for left and right sides with ease. Each side receives three weld points between the spindle and twin chromoly tubes, producing exceptional torsional strength. This exact twin-tube configuration has been Pro Mod tested to 3.6x in the 1/8-mile, proving unmatched durability in extreme drag-race environments.
The longer 7-inch billet 7075 arms offer increased leverage and fine tuning potential - perfect for serious race cars requiring greater control over chassis separation and weight transfer.

Frequently Asked Questions
Why choose 7? ARB arms over 6??
The longer 7? arms provide additional leverage, offering more tuning sensitivity for track conditions and chassis balance.
