The D clutch in ZF 8HP55, 8HP70 and 8HP75 transmissions has a thin, stamped OE backing plate that allows flexing and bowing (coning) of the clutch pack. This wears the clutches unevenly, generating and concentrating extra heat which leads to clutch burnup. The result is slipping or no 4th through 8th and Reverse Gears, as well as ratio codes. Domiworks Engineering heavy duty D clutch backing plate is designed to prevent flexing when the clutch is applied, eliminating a leading cause of D clutch failure.
- 2X thicker than weak, stamped OE backing plate for significantly improved protection against burnup
- Easy to install, no special tools or machining required
Prevent comebacks by installing this backing plate in transmission that have not yet failed yet!
