Crane Cams 11570-2 - Crane Cams Ultra-Pro Mechanical Roller Lifters
Crane Cams Ultra-Pro Mechanical Roller Lifters
Ultra-Pro Roller Lifters feature maximized strength, especially in the axle support struts to ensure geometrically perfect tracking of the roller wheel. Premium wheels, axles, and bearings are made from the finest alloy steel to conquer even the most violent cam lobe profiles. These lifters represent the best combination of lightweight strength and reliability. They are ideal for drag racing where valve spring seat pressures exceed 300 pounds and open pressures are more than 800 pounds. Ultra-Pro Lifters also work on short circle track or endurance race applications with spring seat pressures in excess of 250 pounds and open pressures over 700 pounds.
