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.
For higher horsepower applications, the Force 10.5 dual disc is the natural choice. Based on the design of the original RAM Street Dual, Force 10.5 is more street friendly by using a three strap system to locate the floater plate. This eliminates floater plate ‘rattle’ that is common on stand driven dual disc clutches. A high clamp load pressure plate assures plenty of holding power without excessive pedal pressure. Steel backed 300 series facing mean smooth engagement on takeoff and insure long service life. For higher torque capacities, the Force 10.5N features the proven RAM 900 series metallic facings. Force 10.5 dual disc systems handle bigger torque loads and are a bit heavier than their smaller cousins. This higher inertia translates into better low speed driveability in heavier vehicles, or in large camshaft profile applications. If you are bolting on a larger blower or turbo system, Force 10.5 may be the best choice for you.
