APPARENTLY ... TOO HARD FOR ME....LOL all I wanna do is change out the stock axel to a 3''/ 4'' drop... pretty easy right>>> the axel has juice brakes and a reverse eye spring.. measuring spring pearh center... around 37''... king pins are at 50'' +/- just wanna swap the axel....after market... /speed way all say 46 and 48'' king pins????? can this be done??? what am I missing????????????????????
If all you want to do is lower the car an additional 3/4 inch isn't there an easier way to do it? Re-arch springs? Move the spring perch/ crossmember up? Smaller tire?
I think he is looking for a 3 or 4 inch drop. Common to lose two to four inches when dropping a stock axle. Shorten up the tie rod and you are ready to go.
Yep as you drop the axle the king pin boss moves in. Think of it this way, lay your elbow on a table, move your fist straight out now as you raise your fist while keeping you elbow on the table the flat plane measurement between your elbow and fist gets smaller. Even though the distance between your fist and elbow never change. Now there are/were gents that also stretch the neck of the axle as they drop it to help keep the distance between the king pin bosses really close to factory. So your only choice may be to find someone that has the ability to stretch and lower at the same time... ...
Get an original one dropped (see other HAMB posts for someone) and stretched if you want to keep the same dimensions. https://droppedaxles.com/ford-dropped-axles-0#1933-36 Ford Dropped Axle
