Designed for performance V-twin engines running 185+ lbs of valve spring seat pressure, these lifters maintain proper top-end oil flow and reduce valve float for maximum lift and RPM stability.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eSteel body construction\u003c\/li\u003e\n  \u003cli\u003eFull-travel hydraulic design\u003c\/li\u003e\n  \u003cli\u003eSlower bleed-down rate for high-spring-pressure cams\u003c\/li\u003e\n  \u003cli\u003eSpin-Tron dyno developed and track proven\u003c\/li\u003e\n  \u003cli\u003eCompatible with Feuling HP+ or Race Series oil pumps\u003c\/li\u003e\n  \u003cli\u003eRecommended for strip and performance street engines\u003c\/li\u003e\n  \u003cli\u003eMade in the U.S.A.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Feuling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part #:\u003c\/strong\u003e 4055\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 6.3 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 5.05 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 3.5 in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.21 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003eFits V-twin motorcycle engines, particularly those running large-lift camshafts and higher valve spring pressures above 185 lbs seat pressure.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat valve spring pressure do these lifters handle?\u003c\/h3\u003e\n\u003cp\u003eFeuling Race Series lifters are recommended for engines running valve spring seat pressures higher than 185 lbs.\u003c\/p\u003e\n\u003ch3\u003eDo I need a special oil pump with these lifters?\u003c\/h3\u003e\n\u003cp\u003eFeuling recommends a high-volume oil pump for quieter, better-performing lifters.
