Lifters - Race Series® - Oversized - Twin Cam

Enhance your Twin Cam engine's performance with the Feuling Parts Race Series Oversized Lifters, part number 4052ST. These lifters feature a revolutionary design with just 0.115 inches of total travel, significantly less than traditional full travel lifters that measure 0.200 inches. This reduction in travel increases engine RPM by decreasing valve float and harmonics within the valve train, all while maintaining a quiet engine operation. The decreased oil volume needed to fill the lifter reduces oil aeration during high-speed, high-lift camshaft operation, preventing common issues such as lifter noise and poor performance caused by aeration-induced pushrod seat drops. Designed for both street and strip applications, these lifters are machined from high-quality steel and are compatible with Feuling® HP+® and Race Series® oil pumps. They are engineered to handle large lift camshafts and higher valve spring pressures with a slower bleed-down rate, ensuring consistent valve train stability and maximum valve lift. The lifters incorporate a precision-ground needle roller bearing with a high chromium steel axle, delivering long life and minimal friction. A high-flow disc-style check valve provides quick reaction at higher RPMs, proven through Spin-Tron dyno testing and track performance. Proper installation involves pumping each lifter by hand to expel air, which can be effectively done using a squirt can with thin weight oil such as ATF. For engines with valve spring pressures exceeding 185 pounds, Feuling recommends Race Series® lifters and a high-volume oil pump to ensure optimal performance and quieter operation. These lifters are designed to maintain proper oil flow to the top end, increase RPM, and promote valve-train stability, ultimately reducing valve float and maximizing lift for enhanced engine output. Made in the USA, the Feuling Parts Race Series Oversized Lifters are a reliable upgrade for serious enthusiasts seeking durability, performance, and efficiency in their Twin Cam engines.
