Ultra Pro Series Hydraulic Roller
The Pro Series hydraulic roller revolutionized the hydraulic roller cam business in 2003. This lifter is made from 8620 tool steel and features a .750” wheel. With the ability to use springs up to 220#/525# this lifter will allow an engine to rpm well past the 6500 rpm range and not nose over. The lifter cannot be used with oil weight heavier than 15W40. We recommend 1 full turn of preload. This is a slow leak down lifter.
