For 17-19 M-Eight. HP+® ONE-PIECE PUSHRODS. Feuling highly recommends using one-piece pushrods instead of adjustable pushrods to maintain maximum cam/valve lift and reduce valvetrain harmonics and associated hydraulic lifter issues. Fixed length, 4130 chromoly one-piece pushrods with swedged formed ends. Heavy-duty 7/16" diameter tube with a wall thickness of 0.165". Heat-treated with a black oxide finish. Stock replacement lengths. Designed to work with factory base circle camshaft dimensions. Will work with all stock, Screamin' Eagle and Feuling camshafts. Made in the U.S.A. NOTE: Due to the unstable nature of this 4-valve engine design with one rocker arm activating two valve springs Feuling® highly recommends running one-piece pushrods instead of quick-install adjustable pushrods to maintain maximum cam/valve lift and reduce valve train harmonics and associated hydraulic lifter issues. NOTE: Requires removal of rocker covers and rocker arms for installation. - Part Number - 0928-0091
