    900-Series Clutch Disc

    The RAM RTrack 10.5 has a stand driven floater plate provides ultimate holding power and durability 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.

    The Ultimate in Holding Power & Durability for Street or Strip
    The RTrack Dual is modeled after RAM's highly successful drag racing clutches used in Pro Stock and Pro Mod vehicles. The major difference between these clutches and the Force 10.5 is the floater drive system. RTrack employs a stand-driven floater plate to provide greater torque capacity and negative load for vehicles that see a lot of track time. A 2400-pound clamp load pressure plate produces good holding power without excessive pedal effort. There are two disc series: 300 and 900. The 300 Series has a sprung hub top disc and solid hub bottom disc for smooth engagement. The 900 Series is for higher torque load up to about 1300 ft/lbs so expect some floater plate noise at idle.

    Engineered for today's late model performance cars and older vehicle engine swaps, most RAM Dual Disc Clutches are compatible with factory hydraulic release mechanisms. A clutch's height is critical to proper operation; it prevents the need for spacers or other modification. Dual disc clutches that bolt to a stock flywheel can be a release problem. For clutches that malfunction, add a RAM Internal Hydraulic Bearing.

    The purpose of these clutches is to provide smooth drivability for high power levels that wasn't previously available 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.
