Upgrade your Milwaukee-Eight engine with Feuling Parts HP+® Fixed Length Pushrods. These high-performance pushrods are engineered for durability and optimal valve train performance, ensuring consistent cam/valve lift and reduced valve train harmonics. Ideal for both street and race engines, these pushrods provide a significant upgrade over stock components. Description The Feuling HP+® Fixed Length Pushrods are constructed from 4130 chrome moly steel, offering exceptional strength and reliability. The heavy-duty 7/16" diameter tube with a 0.165" wall thickness ensures superior stiffness and reduces flex, even under high-stress conditions. Precision concentricity and heat treatment with a black oxide finish further enhance the pushrods' durability and resistance to wear. These one-piece pushrods are designed to work seamlessly with all Feuling® stock and SE M8 camshafts, as well as both hydraulic and solid lifters. Feuling highly recommends using one-piece pushrods in the unstable 4-valve M8 engine design, where a single rocker arm activates two valve springs, to maximize performance and minimize issues associated with hydraulic lifters.
