Product Overview
The World American WA24100 Automatic Slack Adjuster is a Meritor-style 10-spline air brake adjuster engineered for precision braking performance in Class 7–8 truck and trailer applications. It automatically maintains proper shoe-to-drum clearance, ensuring consistent braking response and even lining wear.
Designed with a 5.5″ arm length and 1.25″ camshaft diameter (10 splines), this unit is ideal for standard camshaft brake assemblies using a push-rod style actuator. The WA24100’s forged steel body, hardened gear mechanism, and zinc-plated adjustment hardware deliver exceptional durability and corrosion resistance in on-highway and vocational service conditions.
