About This Product

Designed for older Harley-Davidson Big Twin engines, these S&S roller rocker arms are crafted from forged steel for exceptional structural integrity. The addition of roller tips helps to alleviate the friction and side-loading typically associated with standard rocker arms, leading to a smoother valvetrain operation and reduced wear on valve guides. S&S brings decades of engineering expertise to these components, ensuring they can handle the demands of both stock and modified engines. These forged roller rockers are a staple for enthusiasts performing top-end refreshes or performance upgrades. This product is sold as a set to ensure uniform valvetrain geometry across all cylinders.

Manufacturer part number: 900-4320A.
