Which is stronger?

Right now, my rear axle is a Dana 44, full-floating, chromoly shafts, truss, detroited. I want to upgrade to a Dana 60 (probally just stock shafts for a while). I know the ring gear is bigger on a 60, but because the 44 is full float with the chromo shafts, I was told it is as strong as a 60. Anyone have any thoughts?

With a V8, I'd say you could benefit from the stronger ring and pinion. With that said, I think the D60 will fail first with stock shafts over a 44 with chromos that is a full floater.

what did you have to do to make your D44 a ff. I have a 44 rear and want to make it last as long as possible and you've intrigued me.

NVM I figured it out. Damn the prices for a ff kit can vary.

4wheelparts wants 780
but northridge4x4 is at 280 shipped!

I'll have to keep this in mind, w/flanges of course.

Why the upgrade? If it's just "because" I say run the 44 till your breaking it, then upgrade. No reason to spend money to fix something that isn't a problem.

I'd lock up your front end before spending any money on a 60 rear.

what size tires you running?

Presently I have 35's, but in the spring I plan on 37's or 38.5's (depending on budget and how much Id like to trimthe body). I have a spare set of chromoly shafts too. Im just wondering if I should sell this 44, spend the cash for 60, narrow it, truss it and install it. But by the time I do all that, is it just going to be about the same strength as the full float 44?

if you plan 37"+ tires then keep your built rear 44 and sell your front 44 and get a front d60.

then in the future IF the rear d44 breaks then put something bigger in.


when I ran 35" TSL SX on my front d44 I broke every other time I went out!
it gets old fast

You'll eventually break the R&P and be left with having to spend some bucks to fix it. Sell the 44 while its in running shape and maximize what you can get out of it. Use the money to set up a 60 the right way and never look back. My .02.

I say pick up a cab & chassis 14FF. They are 63" wide WMS-WMS, plenty strong for any size tire you want to go to, are dirt cheap, etc. If you get a 60 you will have to bore the spindles out to fit 35-spline axles, shorten it, etc. That is a bunch of money when there is something out there that will just need gears and to be tossed under your rig. I bet you will end up money ahead. Use that money for the front end.

The 60 with the stock 30 spline shafts will never be as strong as your chromo shafts in your 44. Yes, the R&P and the housing is stronger, but 30 spline stock shafts will be the weak link.

Dana 60 and dana 44 shafts are the same exact spline. You can take a 60 shaft and slide it right in a 44 spider gear. The 44 ring and pinion if set up properly and maintained (no loose pinion bearings) will be stronger than the shafts. Dont waste your time.
