POWERGRIP HD is a true "strip/street" competition clutch system that can
handle the rigors of weekend racing and spirited street driving. This
system has the same components as standard POWERGRIP above with the
exception that the disc friction surfaces are both sintered metallic.
Sintered metallic provides a degree of slippage on vehicle launch to
prevent the violent and uncontrollable engagement characteristics of
paddle type metallic discs. This firm consistent engagement is easy to
control. Some chatter is likely on engagement with rear gearing less
than 3.73 in street applications. Each set includes the pressure plate,
clutch disc, release bearing, and alignment tool unless otherwise noted.
Use Powergrip HD for power levels to 650 horsepower, or lower powered
vehicles that see frequent track duty.
