I would look at 4.10s and you will be pleased, especially if it is just an in and around town rig with the occasional beach or trail trip. 33's also brings up a concern if you have the stock Dana 35 rear axle. Look at a 95-01 Ford Explorer 8.8 and you will be set for the long haul.
The goal is to eventually upgrade the axles. Just for more strength and durability. I have some time before the 31's are going to need replaced... probably going to get some axles and fix them up and have them geared and everything before doing the lift and getting the 33's... I'm sure an 8.8 is fine for the rear...not sure how to do the front... was thinking maybe looking for 44's for front and rear...don't need 1 tons...

If you plan is 33 or 35 inch tires the HP Dana 30 upfront is good. maybe upgrade axle shafts but that would be all I would do. There are enough points to make the Ford 8.8 a superior axle to a Dana 44 rear. The amount of time and money you will spend finding a good or matching pair of Dana 44s to swap in is not worth it. If you find a steal then obviously go for it but I would leave the Dana 30 and upgrade the rear to a Ford 8.8 and enjoy it. Especially since you can easily find 8.8's with 4.10 gears, disc brakes and a Limited Slip Diff. Then doing that all you would have to do is re-gear the front. Saves time and money. If you can weld you can save a lot by doing the axle swap yourself, especially since there is plenty of after market support for the 8.8 axle.

I recommend just do some searching for available Dana 44s and then Ford 8.8s and you will find probably 10 ford axles for every 1 pair if not even more 8.8s. If you prefer aftermarket that is an option but the cost is so much MORE than Junkyard axles. I agree the jump to tons is a lot and really shouldnt be done unless you are going to at least 38/39" tires.

Hope this helps some. Looking forward to the progress.

If you are going with 31s, I wouldn't waste time or money on an 8.8 or gears or anything else. The D35 you have will be fine for your use.

The plan is to go to 33's when the 31's I have wear out....

1995-2001 Ford Explorer 8.8 can be found with 4.10 gears, disc brakes and LSD. I do agree with above and if you were to stay with 31s no need to upgrade but for larger tire sizes it would be best if you did.

to expand your search a bit and offer more options...

The Ford Explorer sport-trac i believe carried those same spec 8.8's up until 2003.

Ford Rangers also have the 8.8, but lesser spline count and not as robust... try to stay away from those.

can't find my list but I know the sport trac is not always the right version. ranger almost never. 8.8 was used in f150, crown vic, all kinds of stuff but in different widths and spline counts so be aware if buying one already pulled

Sport tracks utilized drums until 2002. 02-05 (end of the 1st gen) have 31 spline and discs. Funny thing is, these axles ACTUALLY have LARGER disc brake rotors than on the standard explorer 8.8. I assume what was left over from the explorers after '01, went to the sport trac in terms of guts and shell... and they improved the braking.


*shrugs*.

As for why the sport tracs never got the disc brakes until after Y2K? I dont ask.

All Ranger 8.8s were drums and 28 spline during this time (aside from the Fx4)

Just realized this got way off track lol.

OP. Do your lift. Wear out your 31s. With the plan of attack you have, you'll fit the 33s with that same lift.

In the mean time, figure out your gearing and hunt for an 8.8 with 4.10 gearing and to make it easiest... a dana30 with matching 4.10s. If you already have 4.10s, you're already winning the battle.

33s on a 4.0 with 4.10s will be just fine for your purposes.

It did drift off a bit lol. Yeah, I don't mind pulling my own axles from salvage yards so when I'm ready I'll grab one... Might try to find the elusive XJ dana30HP with 410's. Or at least a regular Dana30HP then research during refurbishing...

Your Dana 30 is a HP axle already. I would only swap front axle if you find one with 4.10 gears already. Like @bruinjeeper said before just check your gear ratio. Heck if there is no tag, open up the diff and count teeth. Sounds like you have a good plan. I am looking forward to the progress.

^ this.

And as I stated and @cpia84 re-iterated... you may already luck off your HP30 with 4.10s.

Crawl under there, get dirty and find out the gear ratio.

Yeah... I'll get into it soon enough to see. I'm sure the gearing isn't 4.10 though. When installing the lift components am I going to have to shim the axles to fix pinion angles as well?
