Full-travel hydraulic lifters with .200" of travel engineered for high-lift camshafts. Improve valvetrain stability and reduce valve float. Made in the USA.
Full-travel hydraulic lifters with .200" of travel, engineered for high-lift camshafts and increased spring pressures. Maintain critical oil flow and reduce valve float; recommended for strip and performance street engines.
Performance hydraulic roller lifters, CNC-machined to extend top-end life. Requires removal of rocker covers and rocker arm supports for installation with one-piece pushrods.
Recommended 0.002"–0.003" lifter-to-pin clearance; restores balance and reduces engine noise. Made in the USA.
- Precision-machined billet construction with square sealing surfaces.
 - Longer exit nipples with dual O-rings for improved sealing.
 - Optimized inlet sizing and placement for efficient engine breathing.
 - Five internal drain ports for controlled drainage and splash resistance.
 
Precision billet oil pump and matched camplate increase oil pressure and scavenging volumes. Includes camplate relief valve pre-set to 50–60 psi, added oil feed holes and cam journal groove for improved lubrication. Kit includes pump, camplate, retainer plate, and hardware.
- High-flow 2.250" chrome moly gerotor gears for increased oil volume
 - Precision-machined relief valve; bench tested to seat at 30 psi, pop-off 55–60 psi
 - 42% more scavenge volume and 68% more oil to bearings versus stock
 - Magnet protection and corrected passages to reduce wet sumping and blow-by
 - Requires matching high-flow cam plate (part #0932-0192) for optimized scavenge
