F100 Lowering

I just got a 1966 F100 LB. I want to do the CV swap to it but since the brakes and bushings had been gone through I will work on the exterior/interior first.

How much can I cut the springs before I can not have the beams bent enough to compensate? I just would like to close up the gap abit to give it a better look. Especially when I add the wider tires since the ones I have are 1/2 way to dead.

Or would this kill tires no matter what I do?

It will kill tires.

Cutting the spring really messes with the camber and the beams need to be really bent a lot to correct. The correction often can not be obtained and the you get bump steer.

If you don't mind eating tires and occasional darting its up to you.

If your dead set on cutting springs, don't take more than a coil and prepare to have an old school alignment shop lined up that has an I-beam bender and more importantly someone who knows how to use it.

I have 2 coils cut in my 66 and it was taken to a frame shop that had the equipment to bend the beams properly. I am very happy with the results and for $100 I was able to drop it 3 inches in the front and in the back. I am running a 205/70r15 tire on mine with the current setup. Sorry about the old picture it was from when I first did the lowering and tint but before paint and bodywork.

The only pictures I have of it stock are 99% disassembled with a cab sitting on the frame how I got it. The current state isn't really photographed either I just forget about taking pictures. The beams aren't bad to get bent but around here only one place still had the people that knew how to do it and were willing to I have put 3,xxx miles on it since they were bent and not one issue so I don't see reliability being an issue.

A friend of mine bent his beams to get almost 4 degrees of camber and one of the beams snapped shortly thereafter. There is a fine line somewhere, just be careful not to cross it.

I cut 2 coils out of my old 67. I had a shop bend the beams and correct the alignment. They did not have dropped shocks then. I lowered my mounts two inches to use my stock shocks. They showed from the front under the bumper. I also created splits in my frame and my inner fender wells after wild daily use. I was 22 and it was a 390. Nothing more to say.
