Speed-Pro Anti Pump Up For Extended High RPM Engines
Speed-Pro Hi-Rev (commonly called anti-pump-up) hydraulic lifters feature the same quality material and construction as the conventional hydraulic lifter. A special high strength steel retainer is used to precisely limit the travel of the plunger during operation. With plunger travel limited, adjustable rocker arms must be used to effect a lash adjustment of .000/.002". This then allows the valve train to perform more like a mechanical system, thus allowing high RPM operation. Because of the high RPM capability and the elimination of frequent lash adjustments (which are required for mechanical lifters), Hi-Rev hydraulic lifters are the best choice for all-round engines.
