Super Duty Clutch Discs

300 Series Organic

RAM 300 Series discs are the top of the line in organic discs. Each disc features a high strength eight spring hub assembly utilizing the patented Poly-coil urethane encapsulated damper spring for up to three times the shock dampening of standard springs. Premium quality non-asbestos facing material is bonded to a steel backing for better heat dissipation and greater rotational strength than standard facings. The 300M series discs utilize a marcel carrier to better absorb engagement shock and chatter in street and strip applications. 300 Series race discs use a flat carrier for quicker, cleaner disengagement and shifting, but will be more aggressive engaging when used in street applications. 

900 Series Sintered Iron

RAM 900 Series discs are the high tech alternative for all performance applications. Using a sintered iron friction 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. This clutch disc is recommended for severe duty street and strip applications where driveability is not the highest concern. We recommend only RAM billet steel or aluminum flywheels for use with these discs.

6000 Series Metallic

RAM 6000 Series paddle discs are the refined version of the original patented 3 point Rametallic disc. Sintered bronze metallic buttons provide crisp, clean engagement. This aggressive material allows you to use less static pressure in the clutch and achieve comparable holding power. 6000 Series discs tend to engage very aggressively and will cause clutch chatter if used in a street application. All 6000 Series discs use the Poly-coil hub damper spring for increased disc life and unmatched dampening qualities. Use 6000 series discs for bracket racing, severe duty street and strip, light duty truck pulling, and increased holding power in oval track applications requiring a stock type pressure plate.
