big4294x4 02-12-2002, 07:46 AM I am about to buy an 8 lug Dana 44 from an 80' 3/4 ton Chevy and was wondering if you all knew some specs on it. Looking for... Possible gear ratios? Spline counts? Width (both total width and from spring perch to spring perch)? Anything else that you can tell me? blzn74 02-12-2002, 08:11 AM The Dana 44 axle you are looking at should have 4:10 gears in it,not sure as far as spline count but spring perch width is the same as 1/2 ton and will bolt right up, just make sure you dont damage the brake lines when doing the swap.or :skull: or :nuke: will happen. brector 02-12-2002, 10:17 AM Should be 30 inners and 19 outers.

Some years 3.73 was the default gear on the 3/4s I believe it was still so in 80. Check the glove box door. I think that's still old enough that you didn't have to decipher the codes. If it's anything but the default gear it will be listed on the build tag. Not sure where to check to confirm what the Default gear was. ranger 02-12-2002, 12:22 PM If its a 44 it will have a tag on the front cover stating the ratio. Of course it might have been removed................:skull: CJ-Jeeper 02-12-2002, 05:54 PM I think that would be a 10 bolt, about 69" wms - wms. Not real sure though Shaker 02-13-2002, 06:02 AM Originally posted by big4294x4 I am about to buy an 8 lug Dana 44 from an 80' 3/4 ton Chevy and was wondering if you all knew some specs on it.

Possible gear ratios: 3:73 or 4:10 Spline counts: 30 spline inners, 19 outters has 297X u- joints Width: 68 in WMS to WMS if you get it for less than $300 you did good!:D :beer: :beer: | |
