    900-Series Clutch Disc

    The RAM Force 10.5 has a strap driven floater plate for completely quiet operation and works well for high horsepower street only cars and trucks. Featuring 900 series friction material rated at 1300 ft/lbs holding capacity. 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.

    Force 10.5 is THE Choice to Handle Higher Horsepower
    Based on the original RAM Street Dual design, the Force 10.5 is more street-friendly with a 3-strap system to locate the floater plate and stop the floater plate rattle that's common to stand-driven dual disc clutches. A high clamp load pressure plate ensures enough holding power to manage about 1100 ft/lbs of torque without excessive pedal pressure. There are two disc series: 300 and 900. The steel-faced 300 Series offers smooth engagement & long service life. The metallic-faced 900 Series is for torque load to about 1300 ft/lbs so expect some floater plate noise at idle. Both 300 & 900 series come paired with a billet aluminum flywheel. Ideal for larger blower or turbo setups, Force 10.5 Clutches handle more torque & weigh slightly more than their smaller counterparts. This greater inertia translates into better low-speed drivability for heavier vehicles or those with large camshaft profiles.

    Engineered for today's late model performance cars and engine swaps into older vehicles, most RAM Dual Disc Clutches are compatible with factory hydraulic release mechanisms. The setup height of the clutch is critical to proper operation; it prevents the need for spacers or other modifications to the release mechanism. Dual disc clutches that bolt to a stock flywheel can pose a release problem. For clutches that function improperly with the factory system, add a RAM Internal Hydraulic Bearing.

    The purpose of these clutches is to provide smooth drivability for high power levels that was previously unavailable from single disc clutches with aggressive friction material. The clutch assembly also needs enough weight so it can be driven at lower RPM and maintain vehicle inertia without bucking. If the clutch assembly is too light, low-end drivability suffers. Applications with large camshaft profiles are prone to this and need the inertia of a heavier unit to sustain low-speed drivability. Road race type vehicles, however, benefit from a smaller clutch's lighter weight because the vehicle drives deeper into turns before letting off the throttle and accelerates quicker back to torque range out of turns.
