Dana 60, 70, and 80?

[82Jimmy]

I know a dana 60 is a really popular size...is 70 stronger? And an 80? Do they make an 80? Will it even fit on a Blazer or Jimmy? Saw an add for one for sale in some classifieds. 14bolt=dana 60
? = dana 70
? = dana 80?

Thanks for you help.

From what I know, a 14 bolt is not a Dana 60. They are two different axles.

A Dana 70 is about the equivilent to a Corporate 14 bolt full floater. Dana 80's are found under a lot of heavy duty cube trucks, 3 tons, stuff like that. Something you need a bigger axle than a 14 bolt for, but not a 5 ton Rockwell planetary for. Hope this helps.

14 bolt,(GM), is close to a Dana 70,(1-ton Fords), Dana 80 come in some heavy duty Dodges and Dana even makes a 135, not sure but I believe it went with a commercial duty Dodge

Yea dude, you're right. Those Dana 135's are insane. 13.5 inch ring gear!! Imagine having a blown 502 on nitrous or something and NEVER having to worry about grenading the rear axle.

My father has a Dana 135 in his '99 F-550 Demo crane truck. It came factory with 4.56 gears and posi, damn thing is about maxed out going 65 down the highway, even with the 6 speed standard. But the low end grunt with that powerstroke will snap your head back and you'll row the gears quick to maintain. It's different and neat.
