Thread: 72 Chevrolet Truck rear end

Is it a Dana 60? Could be a 44, but that seems small for the rear of a big block truck.

A Dana 60 with floating axles is tougher than a 9" Ford. Put a posi unit in it and go.

I still much prefer the 9" Fords, if for no other reason then changing gears is so much easier. I always have another center section or three on the shelf with different gear ratio's for different occasions. As for the floater axles, I like them on circle burners, dragsters, and farm trucks. Just don't like the looks of the big huge hubs on the street. Are they tougher??? Maybe, depends on how they're set up and what components are used. As with anything, we all have our own preferences and opinions...

I would go Ford 9", with gearsets from somewhere about 2.5 to 7.5:1 readily available. There are several types of traction devices you can get as well from Equaloc, Auburn, Torsen, Detroit Locker to name a few

The gears in the diff you now have are possibly a stump puller ratio(4.56 or maybe steeper) and not suitable for a daily driver - unless you like contributing even more $$ to the likes of the ExxonMobil cartels.
