Feuling’s® HP+ lifters are designed for use in high lift, high RPM applications. Featuring optimized valving that improves oil flow to the top end while retaining true hydraulic operation, these lifters run quiet and are recommended for use with stock or Feuling’s® Super Pump oil pump. Drop-in performance replacements for the stock lifters. Sold in sets of 4.
USA-made Feuling® Race Series hydraulic lifters are designed to exceed the needs of large lift camshafts and higher spring pressures, while maintaining proper and critical oil flow to valves, springs, rockers, shafts and valve guides. These lifters are CNC machined from cold headed 1018 steel, heat treated and precision ground; internals are held to aerospace tolerances and pressure tested for a slower bleed down rate.
S&S hydraulic tappets have optimized plunger assemblies and metering devises to better withstand forces associated with high lift cams and heavy-duty valve springs. S&S lifters for EV engines incorporate a traditional axle and inner race within the roller assembly.
This simple but effective kit consists of four machined, heat treated and ground spacers that reduce the travel of the hydraulic unit in high RPM situations, thereby eliminating potential collapse of the lifter and its effect on cam timing.
CNC machined billet tappet blocks for ‘86-’90 Sportster® engines. Includes mounting bolts and o-rings. Also used on S&S replacement XL cases that use ‘86-’90 cam geometry; special blocks are also available for use with S&S Special Application cases that have 1/2” offset cam chest.
These oversize tappet pins allow the builder to limit tappet rotation in the lifter bore; excessive rotation allows the lifter to side-load and cause operational issues. Red Shift recommends between .002” - .004” of clearance. Oversized pins are available in +.002” and +.006” sizes.
