The UPR Pro-Series ™Anti-Roll Bar Kit Weld to Fit is part of the Pro-Series ™ Suspension line used by all our racers in eliminating body roll and stabilizing the car down the track. Our Anti Roll Bar features roller bearings and solid 1 1/4" bar to ensure the smoothest reacting kit available! Bar assembly comes partially finished so that it can be installed around tailpipes. Finish welded is required. Anti-roll bar is designed for drag race use only. Links must be disconnected while driving on street to prevent damage. Click here to see before and after results!
