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.
Be sure to include our spindle nut kit () to properly install these spindles.
Includes forged spindles with deluxe kingpin kit.
Application This Part Fits Ford-style spindles are generally your best choice when using an original Ford axle or an aftermarket I-beam axle. This spindle is a reproduction version of the 1937-41 spindle. Ford used the same kingpin dimensions and geometry on the 1928-48 axles, therefore you can use any 1937-48 Ford spindle on any 1928-48 car axle. Charts(PDF)

Pros: These are nicer than the standard spindles way b
Summary: worked out great on my original 1934 straight axle
Yes, I recommend this product.
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.
Pros: Easy To Set Up
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.
Pros: Easy Install And Great St Eering Steering
Yes, I recommend this product.
Summary: The needle bearing do not stay in the housing which makes it Very hard to insert the kingpins without knocking them out. Some kind of lip in the edge of the housing would help to keep them in. I found that if I put the lower bearing in after the kingpin was almost all the way in it worked a little better then the top bearing afterward. It's still better then the original so can't complain with the end result
Cons: Lousy Design On The Beari
Pros: An Improvement Over Origi
Yes, I recommend this product.
