Heavy Duty "D" Clutch Backing Plate

The "D" clutch in ZF8HP45, ZF8HP50, Chrysler 845RE and 850RE 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.

Sonnax heavy duty "D" clutch backing plate 35570-50 is two times thicker than the OE plate which prevents flexing when the clutch is applied, and provides greater durability.

• 2X thicker than weak, stamped OE backing plate for significantly improved protection against burnup
• Easy to install, no special tools or machining required
• Prevents comebacks by installing in units that have not yet failed
