Forged from 8620 steel for strength.
S&S roller rocker arms are stronger and designed to combat excessive valve lift and valvetrain wear with higher lifts of 0.550" and up to a maximum of 0.650" valve lift.
Rocker arm geometry is better suited to higher-lift cams, and the shaft bushings are 50% longer to help increase valvetrain life.
The larger surface area on the thrust surfaces reduces head wear, and oil is sprayed directly onto the valve springs to improve cooling and help prevent valve breakage due to excessive heat.
Comes with standard 1.640 M8 rocker arm ratio.
Note: See 597872 for a complete rocker arm rebuild kit with all necessary components.
Fits: > 17-22 M8
