Get The Classic Looks of 45-Fin Buick Brake Drums for Your Ford Hot Rod with No Machining Required
Preserving traditional hot rod styling and designs of the past is getting more difficult by the day. In the past, acquiring a set of finned Buick aluminum brake drums for your traditional Ford hot rod required hours of rummaging through swap meets and some time on the lathe, machining them down to fit on your 1937-48 Ford spindles - not any longer!
Speedway Motors’ exclusive Buick-style brake drum combines modern design and engineering with the classic 45-fin drum styling of the past. This is not a flimsy cover, but rather a high-quality recreation of the most effective brake drums ever produced. To overcome the inherent design flaws with drum brakes, Buick introduced front aluminum brake drums across all models in 1958. Typical cast iron drum brakes build heat quickly and begin to fade. Hot rodders quickly discovered that the aluminum material and the 45 radial fins radiated heat much faster than cast iron drums. Plus, the weight savings of aluminum made them faster at the drags.
It wasn't easy to adapt this new technology to their old Ford, though. Machining of the Buick finned brake drums was required to correct the offset, clearance the hubs for the drum to fit and change over to the Ford wheel bolt pattern. We've saved you the time, trouble and cost associated with finding and machining crusty old swap meet parts. This all-new improved design of the Buick finned drums features an increase in strength over the OE Buick finned drums, a hub-centric center register for improved safety and handling, and the correct offset built in to clear traditional Ford brake setups. Plus, our 45 fin Buick brake drums are computer balanced internally, eliminating those ugly external weights, providing a smooth ride.
Everything You Need To Install Buick Finned Drums On Your Ford Spindles
These brand new cast aluminum brake drums include a steel brake liner and are machined with the proper clearances to fit directly onto the included 1937-1948 Ford front wheel hubs and 12"x2" Bendix-style assembled drum brake package. All new wheel bearings, bearing races, and wheel seals are included to make installing this complete drum brake kit a breeze on your spindles. If you like the idea of using polished 45 fin Buick brake drums, we offer this kit with polished drums as well. Need spindles too? We offer this Buick finned drums kit with our forged machined spindles as well with king pins in kit form too. These 45 fin Buick brake drums are the perfect addition to any traditional hot rod build.
