Jims Rocker Arm Shafts

Fits 2017-2020 Milwaukee Eight M-Eight Models

In an effort to perfect Milwaukee-Eight engine valve train geometry, while improving durability, JIMS has developed performance rocker shafts and proprietary hardware

The rocker arm shafts are precision machined from a low alloy nickel, chromium, molybdenum case hardened steel.

The hardware flats on the end of the shafts are held to a .0005” parallel tolerance, assuring the rocker is seated in the correct position with the pushrod cup & valve stem tip when installed correctly
