The NEW Platinum Series lifters incorporate the new EDM technology, a patented pressurized oil system. In these new lifters, both sides of the lifter bearing are pressure fed by two oil ports spraying oil directly on the bearing. We have also incorporated and updated the oil feed system that provides oil to the top end and rocker arms 25% faster with 10% more oil. . . many other new features for bleed rate and lifter fill times are also built into the new Platinum Series Directional Roller Lifters.

New Load Divider lifter bearing race designed to distribute an even load across the cam lobes. This feature reduces heat and stress that leads to increased cam and lifter life.

A newly designed push rod Lifter Cup that insures even, proper oil flow through the pushrod to the top end.

New hydraulic Piston Cup and Check Valve that increase bleed time rate. This corrective action gives you performance like a solid lifter but with Anti-Pump Up hydraulic operation.
