FEULING PARTS HP+® Pushrods - Stock Replacement - M8 4087

HP+® Pushrods - Stock Replacement - M8 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, Can be used with hydraulic or solid lifters and street or race engines, Works with all Feuling® stock and SE M8 camshafts, Made in the USA, Requires removal of rocker covers and rocker arms for installation., Due to 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.
