Shaft Mount Rocker Arm Systems offer suppieor rigidity and stability

when compared to conventional stud mount rocker arm systems. Shaft

Mount Rocker Arm Systems also ease access to the valve train,

facilitating valve adjustments and other maintenance functions.


 Our Shaft Mount Rocker Arm Bodies are CNC Machined from

2024-T3511 billet aluminum and utilize a pair of 1,100 lb/ft capacity full

compliment bearings specifically designed for use in automotive

rocker arm systems. The 9/16" steel steel shafts are precision ground on

CNC centerless grinding machines and are case hardened to HRC 58-60

for increased wear resistance. We use 7/16" chrome moly steel ARP bolts

rated at 170,000 psi tensile strength to secure the stands to the cylinder

heads. The shafts are secured to the stands with 5/16" socket style bolts

that meet ASTM-A574 requirements rated at 180,000 psi tensile strength.
