Product Description
Webb 77854BW Vortex 16.5 x 8.62 Balanced Heavy-Duty Brake Drum
The Webb 77854BW is a 16.5 x 8.62-inch Vortex heavy-duty brake drum for drive and trailer axles. It features a balanced, outboard-mount design with Webb’s Vortex cooling-rib construction and a built-in wear indicator.
The Vortex design is the interesting part here. Webb developed the external cooling ribs to move heat away from the braking surface more efficiently. The 77854BW is the Vortex counterpart to the standard Webb 66854B, giving you the same general 16.5 x 8.62 brake configuration with the added Vortex features.
