Designed for outboard-mounted brake setups, the Webb Brake Drum provides a 15 x 4-inch drum built around that configuration. The 10-hole mounting pattern defines how the drum connects to the hub, giving the product a clear structural identity. Its cast drum body forms a solid braking surface rather than a segmented or lightweight design. The outboard mount style shapes how the drum sits within the wheel-end assembly. This combination gives the Webb 64481F drum a defined form tied to its mounting style and braking surface layout.
