The Hendrickson S-31902-1L or S319021L is a genuine Hendrickson S-Cam brake camshaft designed for heavy-duty air brake applications. This camshaft features a hexagonal S-Cam head, a 28-spline shaft, and a 23.75-inch overall length. The S-Cam design is the industry-standard actuator in drum brake systems, converting push-rod force into shoe expansion against the drum. Position is not side-specific per the manufacturer's designation, though confirming fitment against your axle and slack adjuster specs before ordering is always recommended. Pro Gear and Transmission carries genuine Hendrickson brake components. Call us to confirm proper fit for your application.
