Webb Vortex® Severe Duty
Truck Brake Drums

Webb Severe Duty has developed premium Webb Vortex® brake drums designed specifically for severe service applications that typically experience elevated brake temperatures caused by a combination of high frequency of braking events, heavy loads, and harsh operating environments.

Most common truck brake drums are designed for a variety of on-highway applications. Webb Vortex® severe service drums focus on heat management and promote longer brake life and reduced maintenance costs.

Webb Vortex® Severe Duty brake drums
run cooler to last longer.

Excessive heat is your wheel-end's worse enemy. It shortens the life of your brakes and every other wheel-end component... including your tires! Webb Vortex® Severe Duty brake drums run cooler to last longer than standard brake drums. Designed specifically to handle the demands of Severe Duty applications, cool running Webb Vortex® Severe Duty drums are your wheel-end's best friend.
