INTERCHANGE WITH: 3807AX · 66854B · 10012097
Extra-mass version of our 16.5″ × 8.62″ drum for the most demanding severe-service and vocational duty cycles — dump, refuse, mixer, and heavy-haul. The heavier 121 lb casting adds thermal capacity and fade resistance for repeated high-load braking. Interchanges with the 3807AX family.
