Detroit Speed Adjustable Rear Trailing Arm SetThe Detroit Speed Trailing Arms are stronger, but lighter than the stock stamped steel arms and are equipped with high durometer polyurethane bushings to replace the soft, stock rubber bushings. The less weight and reduced suspension deflection results in improved handling, traction, and performance. They also provide increased adjustability in the rear suspension system over non adjustable rear trailing arms. Attributes: Brand Name: Detroit Speed
