  • Sold Ea.
  • High strength steel retainer to precisely limit plunger travel to perform at high rpm operation.
  • Eliminates frequent lash adjustments.



(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 in place of the normal spring clip 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 R.P.M. operation. Because of the high R.P.M. capability and the elimination of frequent lash adjustments (which are required with mechanical lifters), Hi-Rev hydraulic lifters are the best choice for all-around performance engines!
