Description

IMPORTANT NOTICE: This is an 11 in. HD replacement, no dowel pins are required. Clutch will not work with a stepped flywheel. If you have a stepped flywheel a flat flywheel will need to be used.

RAM HDX clutch kits are ideal for vehicles that will see mild street and occasional track use. These performance minded clutch kits will provide more clamping pressure over a stock unit and can handle power levels up to 450 hp. All HDX kits feature an increased clamp load pressure plate while providing smooth clutch engagement with only a slight increase in pedal effort. The HDX clutch disc features RAM's premium organic facing material for optimum performance. Most RAM clutch discs utilize an 8-spring hub to maximize disc strength and durability. All kits include the pressure plate, clutch disc, alignment tool, and release bearing where applicable.
