I’ve got a 55 F100. Been planning to have my original forged axel dropped... Toward that end I saved a good 55 F250 forged axel just in case it was a better candidate for a drop. I know Sid’s a HAMB Member, maybe he’ll see this and have some feedback for me. Here’s my question for anyone who has experience with old school axel drops.; 1) Are king pins between the 53-56 F100 / F250 different sizes? 2) Does dropping and using an F250 axel in lieu of an F100 axel introduce any complications in a successful drop? 3) Is there any benefit to dropping an F250 axel instead of an F250 axel?
