Specifications
Part Details:
Under hard cornering and heavy load, the factory rear differential mount can flex and shift, softening driveline response and reducing rear-end stability. This Cusco Reinforced Differential Carrier reinforces the multi-link mounting points, strengthening the rear end’s structural integrity and improving traction and driveline response without any loss of torque.
Fabricated from high-grade steel with a box-type, hand-welded construction and finished in Cusco’s signature blue powder coat, it arrives with Cusco’s premium rubber bushings pre-installed and ready for a straightforward bolt-on installation.
