QA1 Trailing Arm Bracket - 63-72 C10

These brackets lower the mounting point of the rear trailing arms. A must for lowered vehicles, they correct the trailing arm angle while raising the instant center of the vehicle, which improves forward bite and eliminates rear squat during hard acceleration. Two non-stock mounting locations are available in addition to the stock location, and they will accept QA1, OEM or any other aftermarket lower trailing arms on the market. Grade 8 hardware is included. Made in the USA.
