anybody know what axle and gear ratio is in the longhorn pickup? looks like a dana 60 from a glance.

mtdave2 · 09-10-2008, 02:31 PM

there is mine, not sure what gears are in it, but at 70 mph im running 3100 or so rpm... 373?

Dave, yours should be a 4.10.
hou72che, we need to know what engine and tranny it came with originally, and if the rear looks like the one above.

big block longhorn. does not have that rearend. isnt that a corperate? pretty sure its an automatic? just glanced under it really quik. have had the truck for years but never touched it

if it is a 3/4 ton, then it should be a dana (you are right about the photo, that's the Eaton HO52, or corperate rear) and the gearing should be a 3.54 id a big block and automatic.
If it's a one ton, then 4.10, but I don't think the dana was offered in the one tons.

the orig. engine was the 350...usually see the 3.54 geared dana 60's behind big blocks.

3.54 was pretty much a big block only gear. you could get the dana, but the Eaton is the base model, or standard rear end.

thanks guys im gathering that it is the dana 60 with 3.54 gears.
