These Speedway spindles are a one piece, 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.
Deluxe kingpins feature modern needle bearing inserts that replace the standard brass bushings and are ideal for use on heavier street rods that require superior strength, better lubrication and easier steering.
- Uses 1937-1941 kingpin kit
- For Ford axles 1928-1948
- Will not work with 1928-1936 Hubs
- Includes kingpin kit
Be sure to include our spindle nut kit (910616004) to properly install these spindles.

Nice kit Rated by Ritzy on May 30, 2017
Summary: Kingpin installation instructions were very thorough and were mostly right on. Only real issue was that instructions said to install the thrust bearing "with the lettered side of the bearing facing up", but there was no lettering, so a quick visit to You Tube indicated that the part of the bearing that rotates should face down. I also needed to drive the narrow lower bushings down further to get the lock notches in kingpins to line up. The other small issue I had was that the threads of the set screws did not match those of the zerk fittings that came out of the Speedway spindles, so I still need to source 4 of those to make this complete. I'm still a ways away from being able to tell how it steers with this kit.
Yes, I recommend this product.

Summary: We put it in a 40 pickup and like the way the steering works with a manual box. A friend of ours put it in his and loves it.
Yes, I recommend this product.
