These Speedway spindles are a one piece, drop forged design constructed of high strength 4140 steel, which makes them superior to original components. These spindles are modeled after the '37-'41 round-back design and use '37-'41 Ford kingpins. They fit Ford axles from '28-'48 and can be used with period correct drum brakes or modern Speedway Motors disc brakes, but will not work with hubs from '28-'36.
- Uses 1937-1941 kingpin kit
- For Ford axles 1928-1948
- Will not work with 1928-1936 Hubs
Be sure to include our kingpin kit (91032121) with these spindles.
Spindles also available in kit form with Standard or Deluxe kingpins.
