The Hendrickson D-30594-26L or S3059426L is a brake S-camshaft designed for air drum brake axle applications. Key dimensions: 1.625-inch S-cam head, 28-spline shaft end, and an overall shaft length of 29.5 inches. The cross-sectional envelope measures 3.95 inches across, confirming compatibility with standard Hendrickson suspension and axle brake spider mounting geometry.
