Description

31U3 R & D Marine Damper Drive Plate

Fitted between the engine and the gearbox input shaft, a damper drive plate is designed to transmit the engine power to the gearbox, whilst reducing transmitted gear noise and providing a cushioned drive when selecting gear. All R and D Damper Drive plates include a 'failsafe' design.

Also called the Driven Plate, Damper Plate or Clutch Plate, the 31U3 Damper Drive Plate is from the R and D hammer head element range.
