The Hendrickson S-30594-56L is a brake camshaft designed for S-cam drum brake systems. Part numbers S-30594-56L and S3059456L both identify this same camshaft. It is configured for a 16.5-inch brake drum with a 28-spline output and measures 22.375 inches in length. These S-cam camshafts actuate the brake shoes when the chamber pushes the slack adjuster, making accurate fitment critical. Confirm the drum size, spline count, and camshaft length against your axle specs before ordering. Pro Gear and Transmission sells this as a genuine Hendrickson part. Call us to confirm the correct application for your truck or trailer.
