(1) Cam and lifter wear fears are completely gone. (2)  More power because our composite material has a very low co-efficient of friction. (3) Costly break-in time has been totally eliminated. (4) The ability to run more than one cam, new or used, on the same set of lifters. (5) Our  " Zero-Lash " hydraulic flat lifter customers, enjoy all of the above benefits plus, an increase in RPM, because Schubeck hydraulic lifters are not RPM limited by lifter pump-up.   (6) Schubeck Hydraulic lifters stop power loss from bleed down, (a term frequently associated with lifters that lose valve lift from a leaky hydraulic cylinder).  Schubeck lifters minimize loss of lift because of the limited travel built into our hydraulic unit.
