RAM Clutches for 'stock clutch rule' classes give you unmatched performance and durability. Our 10. 5 inch diameter assembly utilizes a billet aluminum pressure ring with a riveted steel heat shield that provides a durable mating surface for the clutch disc. a 3000 lb. pressure spring provides increased static pressure over stock clutches. Used in conjunction with a RAM six paddle solid hub disc, this combination weighs in at just over 15 pounds. If your rules require a full facing or sprung hub disc, the RAM 300 Series organic racing disc provides the best holding power of any organic disc available and adds only about 2 pounds to the total weight of the set. RAM offers a lightweight 17 pound billet steel flywheel for Chevrolet that matches the above components. If you are required to use all steel components, RAM offers a similar 10. 5 inch pressure plate with a nodular iron pressure ring. This unit uses the same heavier pressure spring for increased holding power. All RAM street stock clutches are completely rebuildable by the factory.
