    Does anybody have any info on what the difference it between a Dana60 rear and a Dana60HD rear?

    And can a Dana60HD be used on a blazer?

    I'm looking into this because I wanted to step up to the D60/14bolt combo with ARB lockers. I had a locker that fitted the 14bolter (Some guy built it) but that one exploded under my Dualy. (Guess he didn't built it that good). ARB does not build a locker for the 14bolt ff, but does built it for the D60 and D60HD.

    Also on this page <a target="_blank" href=http://www.arb.com.au/ALAC/International/Chevy_GMC.htm>http://www.arb.com.au/ALAC/International/Chevy_GMC.htm</a> there are Dana70's. Never heard of them. Usable?

    Thanks in advance.

    Not sure on the 60 and 60 HD, but yes there are D70's and D80's! I think they even go up from there!!

    But do those fit in the rear of a K5?

    Some 3/4 ton, single rear wheel Dodge 4x4's(93+) came with a Hybrid D80. It is a D80 center section with D70 axle tubes and shafts. These could possibly be swapped in, but you may need to move the spring perches and shock mounts.

    D70's could also be foudn under some Ford vans, Ford trucks and Dodge trucks.. Those could possibly be swapped in, but may also need to have the spring perches and shock mounts relocated!

    I found a 3/4 ton dodge that I could get the axles real cheap.
    I went to the dodge forum at pirate 4x4 and asked those guys about them.
    From what they were telling me the D60 FF is about the same strength wise as a corprate 12 bolt.
    They can be made to be as strong as a 14FF for about $1300
    Last months 4WOR did an article on that.
    They bored out the axle tubes and then used 35 spline 1.5" axle shafts.
    Hope that helps some.

    Supposedly the 60HD has 35 spline axles already and are as strong as a 14 where a regular 60 has 30 spline and is same as a 12 bolt.

    I thought I was wrong once,
    but I was mistaken

    That could be true. I know next to nothing about D60's.
    But if that is the case why would those guys spend that kind of money on an axle upgrade when they could prolly get one like that for half the price of what it took to do that to that axle?
    I dunno I am happy with the 14 bolt that I picked up.

    <font color=blue>I think the HD 60s are 35 spline.

    GM used D70's in dual wheel drive trucks in the 80's and I'm told into the early 90's as well. Something to do with GVW rating of the trucks being higher than the 14BFF would handle.
    For all practical purposes, Dana 70 would be an option in a K5 if the 14BFF wasn't available. Dodge has used D60 fronts and D70 rears for some time in their 1 tons.
