Just wondering if anyone has the TCI coil spring suspension with the rear parabolic leaf spring kit on their 1956 F100. What I would like to know is, what backspacing you have IF you are running 15 inch rims. If you have pics that would be great. I am thinking of using 15 x 8 inch factory style rims with 4.5" backspace and 8" wide tires.
Thanks

 

If you are running with an Explorer rear differential I used an 8 x15 rim with a 4 inch back space but needed to add a 1/4 spacer so there wasn'r any tire rub against the box..

 

I have the original rearend on it, have to take a closer look tomorrow. So I guess the 4.5" backspace rims should be fine but I will measure once I have the wheels off. What did you use in front with your Heidts?

 

As it turns out I have an early Ford 9 inch so I will have to wait until I can get the box placed on to measure and mock the front end up to check for clearance.

 

Here is a drawing I did some time ago when I was prepping for a C4 suspension install. No need to install the box...the box is centered on the frame and is about 49 inches wide on the outer edge. Fenders are about 11 inches wide, 10.5 max on the inner lip.

 

You can pretty much order what you want - They make their rear ends inhouse and will make the axles any bolt pattern

Call and ask for Even

 

The track width on that will likely be 60 inches so the 4.5 " back space should work
