    Description

    Jim's Machining 5837 Rocker Shaft Kit In an effort to perfect Milwaukee-Eight® engine valve train geometry, while improving durability, JIMS® 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 and valvestem tip when installed correctly. JIMS has taken it one step further, and developed a 4130 stud and nut kit to replace the stock hardware used to secure the rocker shafts. Compared to a stock “bolt”, these JIMS manufactured studs allow the technician the assembly finesse required when torquing the rocker arm shafts on the cylinder head during engine assembly. These shafts not only improve the stock head configuration; they are a must in a performance application with increased spring pressure.
