    How much ground clearance would I be giving up going from a 10 bolt rear to a SF 14 bolt? Can I use my current brakes and wheels with a SF 14 bolt?

    Not that much clearance difference. Guess it could make a difference in a tight spot. Brakes should come with the axle, but you will not be able to use the existing brakes on your 10 bolt. You will need new wheels, going from 6 to 8 lugs, unless you get the 6 lug. I think they made a 14 SF with 6 lugs, not real sure.
    good luck

    Send the money and buy knew wheels. I've heard that the six lug 14bolt sf just aren't as strong as the 8 lug 14 bolt ff.

    When all else fails MASH the skinny pedal!

    I just got a 6 lug 14 bolt SF, and measurements say I will only loose about half an inch. Maybe a little more, I was under a guy's truck in the parking lot. [​IMG] It's a good axle if you aren't planning on running anything bigger than about 36". I'm only running 35's, so it's perfect. Hope this helps.

    Mybeast, you're right, the 14 bolt SF (which can be had in 5-, 6- or 8-lug patterns) isn't as strong as a 14 bolt FF. That's because they are two completely different axles. The FF is well, a Full Floater, and inherently stronger that way, and also has a 10.5" ring gear compared to a 9.5" ring gear. A 14 SF is a good compromise for those of us who want total reliability without sacrificing ground clearance and aren't running anything bigger than 36" or so.

    When I installed my 14FF in my '85, I had 31's on my 10 bolt, & put 33's on the 14 bolt. I didn't loose any ground clearance at the diff, but it did stay they same. Hope thiis helps.

    Later 1-4x4

    I went from a 12-bolt to a 14bolt FF.
    It hangs down quite a bit more. Not sure how much, but let's see - the 12bolt is 8.875 inch ring, the 14 is 10.5... The radius difference is just about 3/4"... The case is thicker... I guess I lost about 1.5" or less ground clearance. It's such a hog it looks liek more, but I don't think so.
    I'll more than make it up when I go to bigger tires.
    The 14b is stong enough, so even if you don't think it will clear something, just gas it and bang over.
    Please don't try that with your 10 bolt though!

    If I remember correctly 4 wheeler did an article on this a while back and they said a 14 bolt sf/dana 60 was about an inch loss compared to a 10 bolt and a 14 bolt ff was 1.75 inches.

    I've been told that if you go with the 14 ff you should go up two tire sizes to retain the same ground clearance as with the 10 bolt, so basicaly what everyone is saying. If your not going to run anything bigger then 36's you'll be alright with the 14 sf.

    I measured my 14SF and it is 1" lower than my 12 bolt so I am not sure how much lower a 12 bolt is compared to a 10 bolt.
