Anti-Roll Bars from PitStopUSA.com are designed for use in any drag race chassis to control side-to-side body roll during hard launching. They mount between the frame rails of the chassis above the rear axle housing with links that attach to the housing. Anti-Roll Bars are adjustable for preload enabling you to tune for changing track conditions. In circle track applications, installing and adjusting your sway bar correctly will help you to achieve repeatable speed. Whether you run a standard 1 1/8 bar or a 2 big bar you team should have a reproducible routine to ensure the bar is loaded as anticipated every time.
