About this product
Elevate the performance and durability of your Harley-Davidson M-Eight engine with the Feuling Parts Gorilla Rocker Shaft and Stud Kit. Engineered for superior strength and reliability, this kit is an essential upgrade for any rider seeking enhanced valve train integrity, especially when running higher lift camshafts and increased valve spring pressures.
Description
The Feuling Parts Gorilla Rocker Shaft and Stud Kit is meticulously designed to significantly outperform factory components, offering over double the strength for demanding M-Eight engine applications. Crafted from high-grade 4140HT steel, each component undergoes a precise grinding process before being gas nitrated and final surface treated. This advanced treatment not only enhances surface hardness but also provides exceptional wear resistance, crucial for the intense operational environment of a high-performance motorcycle engine. Feuling's innovative custom tooling creates a countersink relief for the bolt/nut head, a superior design choice compared to the factory method of machining away the entire shaft end. This thoughtful engineering ensures maximum material integrity and structural strength, preventing common points of failure under extreme conditions. Ideal for engines running higher lift camshafts and heavier valve spring pressures, this robust rocker shaft and stud kit delivers unparalleled valve train stability and longevity. Proudly Made in the USA, it represents Feuling Parts' commitment to quality and performance for your Harley-Davidson M8.
