The Hendrickson S-31110-5L or S311105L is a genuine Hendrickson S-cam brake camshaft designed for drum brake systems. Featuring a 28-spline hex profile and a 12.25 cam head specification, this camshaft converts air chamber push-rod force into the rotational motion that spreads the brake shoes. The hex configuration and 28-spline count are critical for proper fitment into the camshaft bracket and compatibility with the correct spider and shoe assemblies. Position is not specified as left-hand or right-hand in Hendrickson's own product data, so confirm your axle-end position before ordering. Call us to verify proper fit for your specific suspension and brake configuration.
