Pressure Plates

RAM PRESSURE PLATES

DESIGN YOUR OWN SYSTEM

RAM performance pressure plates are engineered and built to meet the demands of high horsepower street and competition cars and trucks. These are not converted or modified factory stock pressure plates. Each unit features increased or adjustable static pressure, a ductile iron explosion resistant pressure ring, and is precision balanced to within ½ ounce/inch. Over 40 years of racing clutch development and manufacturing assure you that the clutch you select will meet your expectations.

LONG STYLE

The Long Style is the preferred pressure plate for competition. Each unit provides a combination of static and centrifugal pressure, and these characteristics enable the clutch to meet the car needs and track-conditions. Long style clutches provide additional pressure through centrifugal force of the levers against the pressure ring. Pressure plates are available in a variety of static pressures including adjustable static and counterweight to allow precise clutch tuning. All competition long units feature a heavy cover with spring guides.

DIAPHRAGM

Diaphragm pressure plates are for street performance cars and trucks. These will provide the substantially increased clamp pressure necessary for high torque muscle car or crate motor street machines operating in a lower RPM range. RAM diaphragm clutches are approved for heavy duty street and limited competition. For full race vehicles, please select RAM long Style clutches with heavy duty covers.

BORG & BECK

Borg & Beck clutches are best suited for heavy muscle cars and are exact duplicates of the original Mopar and AMC pressure plates. The 10.95 version uses a larger 11 inch pressure ring for more surface area and heat dissipation, and bolts up to a 10.5 inch clutch pattern for smaller bellhousings. For full vehicles, please select HD cover RAM Long Style clutches.
