Right now I have a 7.5 open with 3.45's, that gearing is okay for my 205/75r14 tires but I want bigger tires, and lower gears since the 2.3 is kinda weak lol

Ideally I want 4.10's so I can comfortably run 31's, but I'm having a hard time finding any with that gear ratio.

I've found an 8.8 from a 91 Explorer, 3.73 gears with Traction Loc and it's the stronger 31 spline for $375. This seems like a good deal but I don't know how to weld or even have access to welding equipment, so I'd have to get someone else to relocate the spring perches and shock mounts.

There's also a 7.5 from a 95 Ranger, 3.73 gears and Traction Loc for $400. This would be a lot easier for me, would I miss the extra strength of the 31 spline 8.8? Are these good prices?

If I wanted to cheap out, I also found a 8.8 from an 07 Ranger, 3.73's, open, no brakes for $100.

Should I keep waiting for something to come up with 4.10's, or are any of these a good deal? I would definitely prefer to have an LSD, there's been more than a few times that I've been stuck spinning 1 wheel.

4.56:1 would be a much better ratio for a 2.3L pushing 31s.

If you're limited to junkyard-axle shopping, then definitely hold out for a 4.10 axle (it'll at least be adequate, where 3.73 is more likely to disappoint).

4.10 8.8s are somewhat common in '99-'09 Rangers, and would bolt in.

That is an upgrade on anything. Except 2-ton Rockwells.

That's just what I've found on craigslist so far, I'll probably go to some junkyards soon. But yeah, I shouldn't really bother with 3.73's. I'll definitely try and find at least 4.10's before buying anything. I definitely don't want a higher final drive ratio than what I have now. 4.56's would be great but I doubt I'm gonna find that on the cheap.

My credo
If you're not making mistakes, you're not learning.
Congrats on the deal! I'm still glowing about how well my 4.56 gears are working even on my 235/75R15 tires. When it comes to 4-bangers, do not fear the gear!
