Spohn TBSS Adjustable Tubular Rear Upper Control Arms

Our tubular rear upper control arms are lighter, stiffer and outperform the flexible and soft rubber bushings that come from the factory. Eliminate wheelhop and increase traction with an easy bolt on installation. All ends are fitted with grease fittings for easy lubrication of the fluted polyurethane bushings. Adjustability feature allows for setting your pinion angle and/or pushing the rear back to correct rear end location after lowering (if used in conjunction with our Part #TB-204 adjustable rear lower control arms). Note: Our adjustable tubular rear upper control arms include the air ride sensor mount required for the TrailBlazerSS!
