Royal King Pin Sets for a 47ford pickup

Hello as anyone on the hamb used these King pin sets from speedway...If so what will it involve to change.. I was told it is easier that regular King pins... Any info would be greatly appreciated...

Thanks...

 

I beleive they are made by SSBC in Clarence NY. Check oout their web site- you may find more info or a tech article.

 

I use them. I'm satisfied.

 

Super easy to install. No bushings to ream or hone. DD

 

Thanks guys for your help
