2AM4 R & D Marine Engine Damper Drive Plate

Fitted between the boat 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 2AM4 Damper Drive Plate is from the R and D High Deflection element range. Common applications for the 2AM4 drive plate include Ford or Mitsubishi engines mated to a Borg Warner, Paragon, PRM, Technodrive, TMP, Twin Disc, Volvo or Hurth gearbox subject to flywheel dimensions.
