Short-travel 0.115" lifter for high‑lift cams: raises rev limit by reducing valve float and oil aeration while remaining quiet. Machined steel body, needle bearing, high‑flow check valve; developed and tested on a Spin‑Tron and made in the USA. Preload 0.065–0.070"; fill before installation; compatible with Feuling pumps.

  • New reduced-travel lifter design offering 0.115" total movement instead of the 0.200" of a full-travel lifter.
  • Allows higher engine RPM by limiting valve float and valvetrain harmonics while maintaining quiet engine operation.
  • The reduced travel decreases the amount of oil required inside the lifter, which limits oil aeration on high-lift, fast-acting cam profiles.
  • When air is trapped in the lifter, the pushrod seat can become depressed as the lifter follows the cam lobe ramp after the aeration is compressed, resulting in a noisy lifter and degraded performance.
  • These short-travel lifters should be set with a preload between 0.065" and 0.070"; engine thermal expansion positions the operating preload at about half of the travel.
  • Machined steel body, engineered to tolerate high-lift cams and high spring seat pressures, with a more progressive unloading behavior.
  • Compatible with Feuling® HP+® or Race Series® oil pumps and suited for both street engines and drag-strip applications.
  • Ensures optimal oil flow to the top end, supports higher RPM, improves valvetrain stability, and reduces valve float to better exploit lift.
  • Equipped with a ground needle bearing paired with a heavily chrome-alloyed steel shaft for increased longevity and reduced friction.
  • Fitted with a high-flow, fast-response disc check valve for improved top-end responsiveness.
  • Designed and developed on a Spin-Tron test bench and validated under track conditions.
  • Manufactured in the United States.
  • Feuling® recommends manually bleeding each lifter before installation to remove air and ensure it is completely filled; ATF applied with an oil syringe works well for this.
  • Feuling® recommends Race Series® lifters for engines with spring seat pressures exceeding 185 lb (84 kg).
  • For quieter, higher-performing lifters, Feuling® recommends using a high-flow oil pump.
