Sonnax Heavy duty A and D clutch backing plates

$390.84
HPR front seal kit

The "A and D" clutch in ZF8HP55, ZF8HP70 and ZF8HP75 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 1st/2nd, 4th/5th 7th/8th and Reverse Gears and ratio codes. Sonnax heavy duty “A and D clutch backing plates is designed to prevent flexing when the clutch is applied, eliminating the leading cause of both A and 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
  • Prevents comebacks by installing in units that have not yet failed

    Imported HPR-Tuning product. Original pricing is NOK. Retail price converted to AUD at 0.1504 plus 30% margin for import costs, duties and profit.
