    If you go 3.5", you will probably struggle with pulling the threaded ends of the u-bolts apart to try to get them to line up in the plate holes.

    You gotta trust me (and many, many others on this one), it really is 3 3/8" o.d. tubes on the 14FF. Get a caliper and measure it. Thats how I found out a loooooooong time ago. :waytogo:

    Yeah, it's 3 3/8", I still have the 3.5" pair of u-bolts I had made sitting around somewhere.

    I agree, it's 3 3/8"............however a 3 1/2" u-bolt works fine. Several aftermarket lift companies and a couple of the local spring shops I've talked to don't even offer the 3 3/8" size u-bolts. I used 3 1/2" u-bolts for years with 4" blocks and 38" tires, and a different set with shackle flip (no block) and have never had problems with them on the trail.
