Stock Rule Clutch Disk

The RAM CLUTCH Stock Rule Clutch Disk (model 301M) is a heavy-duty organic friction clutch disc engineered for General Motors vehicles requiring direct replacement of original equipment. This 10.5-inch diameter disc features a 1-1/8-inch bore with 10-spline engagement and a sprung hub design that absorbs rotational shock and reduces drivetrain chatter during engagement cycles. The organic facing material delivers smooth, predictable bite characteristics across a wide range of operating temperatures and engine load conditions.

RAM CLUTCH is recognized within the automotive aftermarket for OEM-specification and performance-oriented clutch components. The sprung hub design on this 301M unit is critical for street-driven vehicles—it isolates drivetrain components from shock loads during hard acceleration and gear changes, extending the life of the transmission and differential. The organic friction material provides sufficient torque capacity for stock and moderately modified engines while maintaining the feel and modulation characteristics drivers expect from a direct OEM replacement. Weighing 4.85 lbs, this disc integrates seamlessly with existing pressure plates and flywheels matched to the 10.5-inch clutch package.

This clutch disc is the correct choice for GM owners performing routine clutch service, rebuilding a worn assembly, or upgrading to a new pressure plate and flywheel combination. The 301M accommodates both manual and automatic-to-manual conversion applications where a 10.5-inch, 10-spline interface is required. Buyers restoring classic or modern GM muscle cars, trucks, and performance vehicles will find this disc meets or exceeds original specification for engagement smoothness and durability under street conditions.
