It automatically maintains correct clearance between the brake shoes and drum as the linings wear, improving braking safety and eliminating the need for manual adjustments. The part fits a 1.5-inch diameter camshaft with 28 splines and has a 5.5-inch arm (center-to-center). It's a straight-arm design, compatible with long-stroke chambers, and comes factory-lubricated with a zerk fitting. Suitable for drive axles and trailer axles on many Class 8 vehicles.
