The Hendrickson S-31110-10R (also S3111010R) is an OEM air brake S-cam camshaft for drum brake axle ends. This camshaft is specified at 12.25 inches with a 28-spline hex configuration, placing it in the brake hardware category for heavy-duty truck and trailer axles. The S-cam head actuates the brake shoes when the slack adjuster rotates the camshaft, converting air-chamber stroke into braking force. Sourced directly as a Hendrickson part, it is sold by Pro Gear and Transmission. Call us to confirm the correct hand and length for your axle application before ordering.
