I want to build my own axle and I need a ford kingpin sleeve. In the attached blueprint it is called a BOSS. I can't find one yet on a Google search or here on the HAMB. I had a catalog from a guy many years ago that sold all the pieces and parts of a traditional build but I don't have it anymore. Craig
Do you mean the ends of the axle themselves, through which the kingpins pass through? https://www.thompsonsgarage.com/hom.../axle_bosses_fit_1937-1948_ford_spindles.html
I cut the ends off a old bent drop tube axle once and used them on a straight axle . Other wise any machine shop could make these fairly easy
I have a set that I would sell. I ended up not using them. These use a set screw to lock the kingpin.
Speedway has several variations of these. But, I haven't found one the uses early Ford passenger car king pins. https://www.speedwaymotors.com/Weld-In-Axle-End-5-2-Inch-x-188-Inch-Wall,37949.html Cheaper than a lathe!
One of my good Friends grew up with Glen the founder of that company. Both now in their 80's and still friends.
any idea which one would fit ford kingpins or should I contact them directly? https://www.hrpracing.com/search?advs=true&cid=0&mid=0&vid=0&q=boss&sid=true&isc=true&orderBy=0
Neither of those will work, you need a boss that is approximately 2 3/8 tall x 1 3/8 dia. with a hole sized for an .813 k/p to pass through easily. Those HRP bosses use later Ford pickup .859 k/p's. I edited the height dimension ^, I forgot about the thrust bearing that goes under the axle boss.
Maybe Scout [International] king pin dia/spindles as they were a thing for a while do to more kingpin angle for enhancing weight jacking in cornering.
They are for sprint car axles based on International spindles originally. I have some stock Ford axles, I can cut the ends off one and send them to you.
Like mentioned above, a chunk of 1.5 inch diameter weldable bar stock, a lathe, and a 13/16 drill bit (0.8125 diameter), and you can make them pretty quickly. Just a little hint, run the drill bit backwards at low speed and using a honing stone, remove a few thousandths from the od. Say 0.005 thousandths. Then get a reamer to enlarge the bores to get the size spot on. Or if you have access to one, a Sunnen honing machine just like used to hone the spindle bushings with. However, leave the finish sizing until after you have welded the bosses to the axle tube.
