One of the most important links in the entire rear suspension is the heavy-duty drag sway bar. It consists of a chrome-moly torsion tube, 6061-T6 billet aluminum swing arms, and adjustable endlinks. Like a street or road race sway bar, a drag sway bar controls the weight transfer of a car from side to side. Unlike a road race sway bar, however, a drag unit is used to preload the suspension. Not only does this prevent excessive body twisting at launch, it also drives the rear end into the ground as weight transfers rearward at launch for maximum traction. As a result, a drag sway bar has no free-play whatsoever, and is far too stiff for a road race application. View Related Article
