Webb Vortex® Unlimited Brake Drums
The Webb Vortex Unlimited features advanced brake drum technology to run 10% cooler than standard brake drums. The patented design employs external cooling ribs that conduct heat away from the brake surface for superior heat dissipation. A patented wear indicator gives you a quick visual reference to take the guess work out of repairs to save maintenance cost.
