Feuling HP+ One Piece Pushrods
Fitment: 1999-2017 Twin Cam Models including 2017-Newer Milwaukee Eight Engines.
Feuling HP+ One Piece Pushrods fixed Length 4130 Chrome moly one piece pushrods with swedged formed ends. Heavy duty 7/16 diameter tube with 0.165 wall thickness, precision concentricity, heat treated with a black oxide finish. Intake and Exhaust length pushrods are stock replacement lengths and designed to work with the factory base circle camshaft dimensions. These pushrods work with all Feuling®, stock and SE® Milwaukee Eight camshafts.
Due to the unstable nature of this 4 valve engine design with 1 rocker arm activating 2 valvesprings Feuling® highly recommends running one piece pushrods over quick install adjustable rods to maintain maximum cam/valve lift and reduce valvetrain harmonics and associated hydraulic lifter issues.
Quick install pushrods are said to be easier to use, however they cannot compare to a solid pushrod for strength and durability
