FEULING 4019 Race Series Hydraulic Lifters

FEULING 4019 Race Series hydraulic lifters are machined from a steel body and designed to meet the demands of large-lift camshafts and higher valve spring pressures. Their slower bleed-down rate helps support valvetrain stability and reliable operation in performance-focused engines.

These full-travel hydraulic lifters maintain proper oil flow to the top end, helping increase engine RPM, reduce valve float and promote maximum valve lift. FEULING recommends Race Series lifters for engines operating above 185 lb. of valve spring seat pressure.

FEULING recommends using a high-volume oil pump for quieter, better-performing lifters. The 4019 lifters are compatible with FEULING HP+ and Race Series oil pumps and are designed for both street and strip engines. Spin-Tron dyno developed and track proven, they are made in the U.S.A.
