Performance hydraulic roller lifters are substantially better than OEM lifters. First, the body is CNC-machined billet steel which is more rigid, stable and dimensionally accurate than OE lifter bodies. They are also of the desirable long travel design, for use with high-lift performance and racing aftermarket cams with up to .700 valve lift. Internal valuing is designed to correctly meter oil at the pressures needed to prevent hydraulic lifter pump up. These lifters have been proven to function reliably at engine speeds of up to 7,000 RPM.


These are the same roller lifters we use in our C6 RXx 2 package . Their performance under high RPM is excellent.
