Offsets vs Factory Trailing Arms

65-82 Corvette rear trailing arms and how offset t-arms work.

Our standard offsets and coilover t-arms offer 2″ of additional backspacing for aftermarket wheels. By moving the parking brake bracket to the top of the arm we gain one Inch, then we offset the entire t-arm between the pivot mount and the bearing mounting surface another inch for max wheel and tire clearance of an additional 2″ over factory trailing arms. The bearing assembly and half shafts remain in the factory location.

These arms are also stronger than factory arm and can’t hold water/moisture like factory arms where they are prone to rusting from the inside-out. Our bearing pivot mount reduces binding in the system which allows for better ride on the street and better handling for the track. Finally, the bearing is held in by a snap ring so it is easily replaced if it wears out. For max wheel and tire clearance, we suggest converting to coilovers which eliminates any leafspring clearance issues. With our standard offset trailing arms, you may need a shortened composite spring to clear your new wheel and tire package. See our wheel and tire chart for C2 and C3 Vette size options.
