    I am looking for a single wheel dana 80. Gears don't mater
    or vehicle it came out of. I have a 14 bolt and it has not
    broke yet, but I have seen my friends brake them. Both are on 44 boggers. one broke the detroit locker. the other broke
    a ring gear. The cheapest one I found in Oregon was $900
    out of a 94 dodge 3500. Does anyone know where one is?
    Thanks.

    Good luck on this one!
    I believe that the heavier "newer style" Dodge pickups (and maybe only the ones with the Cummins or V-10) were the only vehicles offered with a Dana 80 equipped with the standard 8 lug bolt pattern, so they are probably pretty rare in a junkyard. These Dana 80's are actually considered hybrids as it is an 80 centersection (ring and pinion, diff) with Dana 70 axle tubes......most standard 80's were used in larger trucks and had oddball (for light duty pickups) wheel bolt patterns.

    MOst Dana 80s are dually axles, used in 1 ton trucks. My brother's 1 ton Dodge 4X4 (dually) has one.

    I have a buddy who was (about 8 months ago) parting out a '95 Dodge 4x4 that had a Dana 80 in it, and he couldn't GIVE it away!! Too bad our timing wasn't right!!

    My dad's F-550 cab and chassis has a D135 in it. Massive axle, no ground clearance. [​IMG]

    I wonder how hard it would be to break a Dana 135?[​IMG] How much does one cost anyway?

    Steve,
    Tank running gear probably wouldn't be bad. But seriously
    I want to be on 44 boggers with a 509 bill mitchel crate
    motor in a 94 blazer solid axle conversion and not have
    to worry about breaking running gear. I am also actually
    considering a dana 70 front end. I have one but it is drum
    brake out of a 74 dodge fire truck. I would like to convert
    it to disc or maybe even find one that is disc brakes if they do exist. This is a big buck project that will take a
    while so I'm not in a hurry.

    Brian, why don't you just go with 2 1/2 ton axles? My cousin and I are building a mud bogger out of a 3/4 ton 77 Chevy, using 2 1/2 ton GMC axles out of a 60s GMC 6x6 truck. The front axle was BOLT-IN!! The spring pads lined right up. The steering will take a little fabricating to get everything right, but not too bad. They are drum brakes but, they are dual cylinder drum brakes made to stop a truck weighing more than twice as much as the 77. The cool thing about them is running single 20" rims front and rear the tires are completely under the truck (it has a 12" Superlift to clear the 42" tall 9.00 x 20s). Boyce Equipment http://www.boyceequipment.com has 15" wheels that will fit 2 1/2 ton axles so running 44" Boggers is not a problem (the 15" wheels also space the tires out more). And to top everthing off, we got the pair of axles (one front and one rear), and the transfercase (that is a divorced case) for $150, YES I said $150 for a transfercase and two 2 1/2 ton axles!!! And the guy we bought them from begged us to get the chassis out of his yard as soon as possible. Boyce Equipment also carries Detroit lockers for the 2 1/2 ton GMC axles, as well as replacement parts. Even freshly reworked GMC 2 1/2 ton axles from Boyce are cheaper than Dana 60s.
    Another guy that bogs in our area runs 2 1/2 ton GMC axles under a short box full size frame, with an S-10 pickup body, with 52" tractor tires on it, and he drives right past the guys stuck in 4x4 with 44s, in two wheel drive!
    Sorry so long but I think you'll save a lot of cash if you just switch to 2 1/2 tons.

    Jeff,
    Thanks a lot for all of your info. I really had never considered going to 2.5 ton because of ground clearance and
    cost. But I will be checking into it. You got a smoking deal
    on your axles. I would love to find parts that cheap. When
    you get your 77 done, I would sure appreciate an E-Mail picture at sgrossman@coinet.com Again thanks for all the info.

    Brian, I emailed some pics even though it isn't done yet. I don't think you'll lose that much ground clearence going from Dana 70/80 to 2.5 ton. You may be able to get better clearance with Rockwell axles over GMC, but I'm not sure. I haven't worked with Rockwells. You may want to compare them. As far as finding deals, if you just keep your eyes peeled and aren't in a rush, you can usually come up with some good deals.
