GORILLA M-EIGHT ROCKER SHAFTS & STUD/NUT KIT

FEULING M-EIGHT GORILLA ROCKER SHAFTS + STUD/NUT KIT

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

After having a rocker shaft failure road racing our 2019 Harley-Davidson Road Glide 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 & especially for engines running higher lift camshafts & heavier valvespring pressures.
