ZF S5D310Z/S5D320Z 5-Speed Transmission Rebuild Kit

The Race German ZF transmission rebuild kit is a basic refresh solution for the 5-speed S5D310Z/S5D320Z transmissions found in popular BMW models such as the E36, E39, Z3, and E46. These ZF transmissions are known for their robustness and suitability for high-power applications, including engine swap projects. However, with mileage, they can develop leaks or simply benefit from a refresh. This basic kit focuses on the essential components needed to address leaks and restore integrity. It includes an Input Shaft Seal, Selector Rod Seal, and Output Shaft Seal. For those undertaking a transmission removal or a detent kit installation, this rebuild kit offers a convenient way to service other critical areas simultaneously. If you are looking for a more comprehensive solution, Race German also offers a Deluxe Kit which includes additional components like a Foam Selector Rod Bushing, Pivot Fork Guide Tube, Pivot Fork, Pivot Pin, Pivot Pin Spring, and an option to upgrade the pivot pin to stainless steel. The manufacturer also offers a separate ZF Detent Repair Kit for those seeking to improve shift feel and crispness.
