Images are representative, actual product(s) may vary Vertical locking bar Crane Classic Mechanical Roller Lifters were developed when camshaft lobes were not nearly as violent as today. They are ideal for street rollers, many bracket-race type applications and other racing uses where cam profiles aren't as aggressive. Made of carburized (heat-treated) 8620 alloy steel, these rollers are capable of handling up to 240 lbs. of valve spring seat pressure in bracket race applications and up to 220 lbs. of seat pressure in endurance applications – providing the cam lobe profile is not extremely violent. Open pressures exceeding 600 lbs. are not recommended for these lifters. Crane Classic Lifters feature high-quality wheels and axles that “look alike” lifters do not have. These roller lifters feature all the quality and durability you expect from a Crane Cams product, yet they are very economically priced. Crane Ultra-Pro Roller Lifters are the ultimate in state-of-the-art, drop-in design premium quality roller lifters. Empirical design and development techniques have been used to eliminate any distortion effects of residual stresses resulting from the heat-treat process. Ultra-Pro Roller Lifters feature maximized strength; especially in the axle support struts. This ensures geometrically perfect tracking of the roller wheel. Additionally, super-premium wheels, axles and bearings made from the finest grades of alloy steels are used to conquer even the most violent cam lobe profiles. These lifters represent the best combination of lightweight, ultimate strength and reliability. They should be used in all drag race applications with spring seat pressures in excess of 300 lbs. and open pressures over 900 lbs. In addition, they should be used in any short track circle or endurance racing application where valve spring seat pressures exceed 250 lbs. and open pressures exceed 700 lbs.
