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 capability. This clutch disc is recommended for severe-duty street and strip applications where drivability is not the highest concern.
