Dana 60 3.23 gears?

[Simonsays]

Anyone try out doc differential 3.23 gears for Dana 60 rear ends? I've noticed they are the only one I have seen offer it. I have a 66 gmc 1500 with a 4 speed granny tranny being pushed by a chevy 350 short block. Was looking for more hwy cruising speeds. Current gearing can pull a house but it screams past 50. Thanks

I don't think the dana 60 will support a 3.23:1 gear set. I believe a 3.54:1 is the lowest you can go. The 3.54:1 is what I installed in my truck with LTX M/S2 LT235/85R16E tires. On the freeway I believe at 60 mph my rpm is around 2200.

By the way - We normally support GMC V6 engines and not the other brand.

I guess he was referring to this site that lists them.

Yeah, that's what I ran into in a search. Contacted them and they said it will fit a standard DANA 60 with a 3 series carrier. Also stated it needs I believe a 27 spline pinion yoke. Was just wondering who has tried them if any. Or am I going to be the guinea pig for the site?
