Leaf spring bolt dimensions

[Bubi]

Hello,

I want to restore the rear leaf springs of my f250 - and lowering them 2" or 2 1/2"...
But I'm afraid the bolts (not the U-bolts) rip of, when I remove them.
In germany maybe it is a problem to buy inch-bolts in special dimensions.
So I like to buy them, before I try to remove the springs.
Could anyone tell me the dimensions of them?


Thank you very much.

Regards

Volker

Hi Volker,
Which bolts do you mean?
The Spring eye bolts? Do you have a flexomatic spring or standard?

Cheers

Hello,

the spring eye bolts, yes.

With flexomatic.

Thx

I think the 3 rear bolts are 9/16 UNC x 4" and the front bolt is 5/8UNC x 4"
But I´ll confirm that tomorrow when I´m at my workshop.

Anyway - you´ll get the right bolts in germany with no issues.

Confirmed!
But the upper 2 rear bolts are not loose bolts, they are welded into the shakle.
