QA1 Trailing Arm Relocation Brackets lower the mounting of the rear trailing arms. They correct the trailing arm angle while lowering the instant center of the vehicle, which eliminates rear squat during hard acceleration. Two non-stock mounting locations are available as well as the stock location, and they will accept OE or aftermarket lower trailing arms. Grade 8 hardware included. Welding required for installation.
