61 is not really sought after, I thought it was more common in vans.

mac 'and definitely different than a 60' gyvr

I'll have to crawl under and look, which is going to suck since it's parked over broken up cornstalk bales. I think the axle code is c3 which could be 60 or 61 from what I've read.

I may be looking for a diesel zf5 too.

What's the deal with the Dana 61?

With mileage and emissions concerns rising, at some point Dodge and / or Ford decided they wanted to be able to offer gears higher than the current highest ratio of 3.54 available in the D60. However, because of the design of the D60 the pinion head could not be made big enough to achieve a higher ratio. Hence, the birth of the Dana 61, which has a different casting that moves the pinion over 0.25"-0.437" (conflicting reports) - this allowed for a 3.07 axle ratio. The Dana 61 also uses 3.5" axle tubes. Other than that, it is very similar to the Dana 60. The Dana 61 was common in Dodge front ends and Ford van rears.

The difficulty with the Dana 61 is very limited gear and locker choices. However, you can use a combination of ring gear spacer and thick gear set to allow the use of differentials and gear sets intended for the Dana 60.

Slagburn reports: to run a 4.88 I had to go with series 3 carrier, series 1 being 4.10 and down, series 2 being 4.56 and up, then the series 3. PLUS a .160" spacer. That's the problem, nobody makes a full case locker for a 61, but it could be doable with a thick ring gearset AND a spacer.

Reider racing< Randy's R&P, and other sources make ring gear spacers for the Dana 61 .

either way, the rear d60 isn't the best axle choice out there for strength. 60 rears are only worth ~$100/$150

cutting up a 14 bolt seems the way to go

70-1SU

Think is 3.54 and limited slip.

 

[87manche]

all the BOM information is at the d60 bible I linked, but google says that's a super 70.

So what's it worth?
I plan on putting my 10.25 under it.
I tried getting bom but couldn't get it clean enough to read and laying on cornstalk SUCKS.

 

[87manche]

no idea. but if it's a super 70 it should be 4.1`0 or 4.56, so I'd imagine spome big dumb mudtruck guy would want it.

 

[*89Laredo*]

Hmm. Might be 4.10. I'll have to crawl under again with some emery paper and try to clean up the bom.

Thinking this was swapped in. C3 should be a 3.54 ls 60/61.

Solid floors.

 

[RedHeep]

I gave up and rented one of those big Johnson's. Finished it in less than an hour.

Now to clean up the edges and seal it.

 

[MKR5150]

If its a 70 it's worth about 200-500 depending on gears.

 

[*89Laredo*]

One step closer to a free truck if I can sell it.
