The MWC HD/race style panhard bar is made with mild steel tube and TIG welded threaded tube adapters. This allows for the use of heim joints on both ends for on-vehicle adjustability, as well as keeping suspension geometry consistent. In performance applications we prefer the use of heim ends vs poly inserts. The use of poly in suspension parts will always allow movement, thus changing your effective rear end geometry during vehicle weight transfer (ie: launching off the line). This also stacks with the more poly parts on a vehicle = the more allowable movement and loss of initial suspension settings at weight transfer. The MWC panhard bar uses factory mounting locations and can be used as a factory replacement, or in 1500hp+ applications. Also available in chromoly for an additional $30, but please read here for chromoly option.
NOTE: To use the PHB replacement hardware you must drill out the chassis and housing brackets to 9/16.
