a dana 30 was great for what it was designed for. a hemi car or a 440 six pack car is not a hd truck. ok I got you the nine inch was only good for a stock car but the dana 60 was good for cars ands hd trucks up to 4 tons. it look like the dana is better to me lol


UHM, no....the dana 30 was used in the front of AMC Jeep CJ's, Chrysler YJ's and TJ's and IHC Scouts, never in the rear. The Dana 35 was Used in the Rear of the Chrysler products, used C clips and was a piece of garbage that people swap out a Dana 44 for. The 44 was used in every half and some 3/4ton trucks ever sold in the US up until the mid-90's as an optional/available axle. The 60 was put in a few Mopar cars, Some 1/2 ton, most 3/4 ton and a few 1 ton truck from all of the manufacturers up until the mid 90's again. Dana 70's cam in 3/4 ton and up to 1.5 ton trucks....the 80 is even bigger...so while you may have the right idea, be sure of what you know.

I have been around 4x4 vehicles long enough to spot a dana pretty quick. Now an AAM that was put in a GM or Dodge...not so much. More options available for the Dana's to upgrade in the truck world. Most 60 truck internals interchange with the car 60, the only real differences were semi floating axle shafts (some jeep and ford 1/2 tons were semi float) and a mount for a pinion snubber. If you don't need the pinion snubber, then the truck housing will work and not cost a lot.

If someone wants to upgrade to Cromemoly tubes and weld them in, just press out the old and in with the new, then weld. I am personally more worried about the casting flexing than the tubes, but that is from my experience with them in the 4x4 world. a 3.5 inch .500 wall tube takes about 2k horsepower to start bending a tube, the gears would probably spit out long before then without upgrades. I also would build a dana with the Ford Torino ends, there are lost more options for production disc brakes and they were better bearings than came in any 83/4. A Ford 9 is a good axle but most only build them too run right at the edge of almost wanting to break because that is lighter. I run a dana because I never want it to break and don't care about the extra 15-30 lbs. Tim
