Rear Axle diameter
 

I am starting to get some parts for my rear 4 Link. Does anyone know what the diameter of the rear axle tubes is. I have the FX4 so i know they are bigger then normal rangers.

8.8, 31 spline = 3.25

sweet deal thanks man.

lol newb

what year FX4? is it a level II? depending on which one, you could have the 31 spline or the 28 spline...each with different diameter axle tubes....

So you feel comfortable building a 4 link for your truck but can't measure the axle diameter? haha ;)

lol, i thought the same thing.....
