I have a 54 F100 I am working on. My plans are to put a mustang 2 front suspension on with air bags and 2" drop spindles (in progress), and put a 4 link on bags in the back with a 9". I am looking for a 9" but don't know what width I should go with. I don't want to tub the bed but I still want some depth to my rims. I have been looking for about 58" hub to hub.
Anybody got any ideas or experience with this?

 

I think the stock rear track is 60 inches (drum face to drum face?) and if at 58 in. the wheels / tires will clear the in side of the box / fenders / springs then good, you can use a deeper (offset) wheel?

Look in the article / specs section there is an awesome article that tells you just about everything you need to know about the front and rear suspensions.

Here is a link to the article mentioned above:

OH, and welcome to FTE!

 

Use this to measure whats in place now - put the numbers on the top side (axle plate/drum face, center of spring pad. etc)
Now you have something to work from

 

Thanks for the help. I am still trying to find the right size but all the info is making things alot easier to find what I need. Would like 31 spline, trac-loc.

 

Welcome to the board! Explorer 8.8's have 31 splines and usually have trac-loc....plus can have disc brakes. Downside(?) is 5x4.5" wheel pattern.

Most 9" rears I know that have 31 splines and trac-loc are '73 and newer 4x4's.... Too wide. (there are some earlier 31 spliners though.)

 

The 9" I have is (according to Number Dummy) from the mid 60's. Heavy Duty; Police, T-bird or wagon. It's 57" from flange face to flange face. It currently has 28 spline axles and I am going to buy the 31 spline axles and trac lock for it. The bolt pattern is currently 5x5.5 and I want to go 5x4.5 for better wheel selections and disc brakes. Wilwood does not make a kit for the 5x5.5 pattern on the 9" (or so the guy I talked to told me.)

I like the new Mustang wheels and I can put 18x10 on the back and still fit everything inside the fenders. I plan to tub the bed for a little more room and a bit wider tire. I have removed the leaf springs and put a triangulated 4-bar set up with Air Ride Tech shockwaves in it. That gives me 4" more space on each side to get a wider tire under the fenders.

Good luck with your truck.
