Rear Differential Pinion Distance Collar
The Cusco Pinion Distance Collar is made more solid and designed to withstand the abuse of constant acceleration and deceleration, and is recommended for vehicles putting out more power & torque than the factory output.
Inside the rear differential member lies the gears and mechanisms of the limited slip differential. Once the LSD is upgraded to a clutch unit and more load and power is transferred to the rear end, some components begin to wear and tear more faster than others. Typically, the rear pinion spacer that is located on the pinion gear shaft start to crush and cause excessive play between the pinion and ring gear. (backlash)

The Cusco Pinion Collar is made to withstand harsher abuse and serves as an added insurance when rebuilding the rear end.
