Changing Gears

[ksbeatty]

I think I want to change gears in my GM Corp from 4.10 to 3.73's or 3.42's? Then i will have to change the front also which is a Dana 44. I have done some poking around but really have not found some overall directions. i assume if i buy used it is a direct bolt in if i can find them.

Any links or thoughts?

I think you are taling just changing the gears. If that is what you are talking about, it's not a direct bolt in and they will have to be set up. I've done it a couple of times and it's a real ***** and time consuming process.

i guess I am talking about the gear set. So drop the front of the axle out and replace it with another.

You won't find anything better than 4.10... there was a 3.90 that used to be avalible in the aftermarket, but 4.10 is as freeway friendly as you'll find for that rear.

So what do most people do? Do they just swap them out? I have another 3/4 ton rear at the house from a 69 2wd. I will take a look at what it is. What about the Dana. I would assume that is as common as a house mouse.
