Info
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 brake drums for the rear of your traditional Ford hot rod required running a weak, closed driveshaft-type rear axle that would quickly fail when paired with a SBC - not any longer!
If you're looking for a budget-friendly and rock-solid rearend to complete your upgraded driveline with an added touch of 60s hot rod style, look no further. For the first time ever, you can buy a brand new 9" housing that comes with an axle flange designed to fit 30s-40s Ford backing plates, and a custom axle offset specifically designed for Buick Finned Brake Drums or early Ford iron drums. These fabricated steel Ford 9" rearend housing kits feature all-new components for maximum durability. This 9 inch Ford axle housing is pumpkin-centered, which will offset the pinion yoke about 1". This is done to make fabricating a triangulated 4-link system much easier. Simply weld on your preferred brackets, slip in the included 31-spline axles and add the 3rd member of your choice (sold separately), and you have yourself a bulletproof vintage axle!
Kit Includes:
Ford 9 Inch Rearend Axle Housing Kit, Early Ford Style
Total wheel-to-wheel mounting surface width is 56" (from hub-to-hub). The pumpkin is centered in the housing, which puts the pinion 1" offset from center, requiring different length axle shafts. This 56" housing kit includes one 28-5/8" long axle and one 26-3/8" long axle. These axle housing kits are specific to this brake configuration, meaning it's never been easier to run finned Buick drums on all four corners of your ride! Flanges are drilled for 5 x 5-1/2" bolt pattern
Includes the fabricated housing, a pair of axle shafts with bearings and seals, heavy-duty retainer plates, and 1/2"-20 Ford/Mopar wheel studs. Also included are (8) T-bolts for the axle bearing retainer plates and (10) studs for the third member.

Buick-Style Finned Aluminum Brake Drum for Ford Spindles, 12 x 2
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 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 - those days are over!
This all-new Buick-style brake drum combines modern design and engineering with the classic stylings of the past. This is not a flimsy cover, but rather a high-quality recreation of the most effective brake drums ever produced. This all-new improved design features an increase in strength over the OE Buick drums, a hub-centric center register for improved safety and handling, and the correct offset built in to clear traditional Ford brake setups. Plus, it's computer balanced internally, eliminating those ugly external weights.
These brand new aluminum castings include a steel brake liner and are machined with the proper clearances to fit onto 1937-48 Ford hubs, as well as any 12" x 2" Bendix-style brake configuration with a 5 x 5.5 wheel bolt pattern. They are the perfect addition to any traditional hot rod build.

Notes
Few things distinguish a 1960s-era hot rod better than Buick finned brake drums. The fins poking out from inside the wheels and spinning along with them was a killer look, but more importantly, it showed you had some serious ponies that required some serious stopping power. When Buick debuted their finned drums in 1957, progress in the automotive industry had been moving at a lightning pace. A mere ten years earlier, a hot ride had 130-150 horsepower - when Buick debuted their finned drums, serious rodders and racers were pushing 350 horsepower. To go along with this nearly 135% increase in power, cars were getting heavier and utilizing automatic transmissions. All of these factors combined meant that your brakes were needing to stop more weight, with more than twice as much power, and without the help of engine braking from a manual transmission. This combination meant that the usual braking systems were incredibly strained, even one high-speed stop or long downhill road could double your stopping distance from heat-induced brake fade, or worse, complete overheating failure in extreme situations. Buick's solution of adding fins around their drums to disperse heat, while constructing them from a combination of aluminum and steel for maximum weight savings took the performance industry by storm.
If there are two things that aftermarket automotive enthusiasts understand, it's weight savings and the importance of cooling efficiency. Rodders quickly figured out how to fit these state-of-the-art finned drums on the front of their hot rods with a bit of machining and drilling. In rare instances, you can find someone who had fitted the rear of their car with these stylish drums, but that process was far more labor-intensive than the fronts - discouraging those who weren't inclined to engineer a setup from scratch. If you've been daydreaming of Buick Finned Drums on all four corners of your ride, but haven't felt up to the task of the fabrication required to make them work - this kit is exactly what you need.
