Feuling 1231 Rocker Shafts Stock Replacement Harley Milwaukee Eight 17-Up

FEULING M-EIGHT ROCKER SHAFTS

Designed with strength in mind, with over double the strength of the factory and or our competitors shafts. Precision ground from 4140HT steel, gas nitrided and final surface treated.

After our rocker shaft failure road racing at Laguna Seca in 2020 we decided to source the best possible material and heat treat process available to create the best rocker shaft on the market. Custom tooling was created to provide a countersink relief for the bolt/nut head verses machining away the entire end of the shaft per the factory design.

Recommended for all M-Eight engines and especially for engines running higher lift camshafts and heavier valvespring pressures.
