The Webb 56864B brake drum is a standard-duty drive or trailer drum designed for semi-truck and trailer applications. The innovative design of the Webb 56864B makes it perfect for any application that requires high heat transfer efficiency, cooler operating temperatures, and extended service life.

The patented Cool Running Technology (CRT™) vents in the Webb 56864B brake drum allow air to flow through the wheel-end, increasing heat transfer efficiency by 10% over similar-weight drums. This means your brakes will last longer because they are running cooler.
