RAM "PowerGrip HD" 909, 89~95 ZR-1.  10-1/2" diameter x 1-1/8" x 26 spline

RAM 900 Series discs are the high tech alternative for all performance applications. Using use sintered-iron material borrowed from high horsepower Pro Stock and Pro Modified clutches, 900 Series clutches provide extremely high coefficients of friction with minimal chatter and reduced static pressures. This type of material is engineered to provide a limited amount of 'slip' on engagement that allows the clutch to engage without overpowering the tires.

All 900 Series discs use the high strength eight spring hub and Poly-coil springs for extreme dampening capabilities. Recommended for severe street duty and strip use, where street drivability isn't a high priority. Do not use them with an OE flywheel.

This disc is best used with any of the following single mass flywheels with RAM Push Release conversion
