Its high-volume oil system components are a standard upgrade on high-mileage and high-output Twin Cam and Milwaukee-Eight engines.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp style=\"line-height:1.65;\"\u003eFeuling HP+ Roller Lifters are full-travel hydraulic lifters engineered for performance V-twin engines running aggressive camshaft profiles and high valve spring pressures. Their robust steel-bodied construction and slower bleed-down rate are critical for maintaining consistent oil flow to the top end. This design not only increases RPM capability but also significantly reduces valve float.\u003c\/p\u003e\n\u003ch3 style=\"margin:20px 0 6px;\"\u003eWhy riders pick this\u003c\/h3\u003e\u003cul style=\"padding-left:20px;margin:0 0 16px;\"\u003e\n\u003cli style=\"margin:3px 0;\"\u003eSteel body for high valve spring pressures\u003c\/li\u003e\n\u003cli style=\"margin:3px 0;\"\u003eSlower bleed-down rate for consistent top-end oiling\u003c\/li\u003e\n\u003cli style=\"margin:3px 0;\"\u003eReduces valve float and improves RPM capability\u003c\/li\u003e\n\u003cli style=\"margin:3px 0;\"\u003eDyno developed and track proven for reliability\u003c\/li\u003e\n\u003cli style=\"margin:3px 0;\"\u003eStreet and strip engine capable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhen pushing the limits of your Harley-Davidson or Indian Motorcycle engine, especially with aggressive cams and stout valve springs, the valvetrain needs components that can keep up. Feuling HP+ Roller Lifters are built to excel in these demanding conditions, providing the stability and control necessary for maximum valve lift and sustained high RPMs. They are a crucial upgrade for any serious performance build.\u003c\/p\u003e\u003ch3\u003eUncompromising Valvetrain Stability\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSteel body construction handles valve spring pressures above 185 lbs seat pressure\u003c\/li\u003e\n\u003cli\u003eSlower bleed-down rate ensures proper top-end oil flow\u003c\/li\u003e\n\u003cli\u003eReduces valve float for enhanced valvetrain stability\u003c\/li\u003e\n\u003cli\u003eIncreases RPM capability and promotes maximum lift\u003c\/li\u003e\n\u003cli\u003eSpin-Tron dyno developed and track proven for reliability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePerformance for Street and Strip\u003c\/h3\u003e\u003cp\u003eThese HP+ Roller Lifters are designed for both high-performance street engines and dedicated race applications.
