Detailed Product Description

DuraGo BD8101 is a brake drum engineered for specific classic vehicle brake systems, including Chevrolet Bel Air rear and front applications, Chevrolet Impala rear applications, Chevrolet Corvette front and rear applications, Chevrolet El Camino front and rear applications, and GMC G15/G1500 Van front and rear applications. The drum’s composite construction and precise dimensional profile help maintain proper drum-to-shoe contact and mounting alignment for the listed vehicles. This part cross-references Bosch 8101 and FEL-PRO 2003 for the same application.

DuraGo has a long history in aftermarket brake manufacturing, and this brake drum reflects that focus on catalog accuracy and application-specific coverage. The BD8101 part number is a practical choice when replacing a worn or out-of-spec drum on a compatible Chevrolet Bel Air, Corvette, or GMC van brake setup.
