axle question. Dana 30 front and 8.8 rear

just finished up with my 3" lift from zone. Awesome! Right now I have dana30 up front and the 35 in the rear with 31"s. The goal is to be running 33"s.

After doing some reading I and wanting to find a 8.8 with some 4.10's already in it and just regear the stock dana 30 to match. This is my first time switching axles or anything like this, so basically I want to know if this will work? And if iam overlooking anything? I am on a budget and do not need top on the line. Mainly an on road during the week but want to be able to take if offroading and not have to worry about anything breaking. Thank you

I wouldn't run an 8.8 if 33s are going to be your max tire size.

I agree. An 8.8 is best suited for 35s and larger. Either get a D44 or an S35 kit. I run the 30 spline c clip eliminator kit with an Ox locker and I love it.

Sorry. Should have mentioned that I do want 35's down the road.
From what I have seen on the forum an 8.8 is a lot easier to find used and also cheaper then an d44. What is wrong with an 8.8 on 33's?

The pumpkin hangs low. If your thinking about 35s then an 8.8 is a good option. Consider skipping 33s, build for 35s then make the jump.

Being "on a budget" but planning to build for both 33s and then shortly later 35s? Not compatible. I personally wouldn't go for 35s unless there was a really pressing trail need but if you do want them, you will save a boatload of money skipping the intermediate step.

Alright thanks guys. Appreciate the input! I am wondering though with the pumpkin haning "low" with 33's. Is that more of an issue when rockcrawling or offroading. How does it do on road? And also how low does it actually hang? Would I be fine with wild offroading. Thanks again for help. Asking because I have seen a few on here running an 8.8 with 33's and never heard of this clearence issue.

Been doing some reading today and have decided to just up to 35's and getting the 8.8 with 4.88 gears. Is a 3" enough height to run 35's or should I start looking for a body lift too. Thanks

The pumpkin hanging low will probably be fine for you. You really have to build to the type of wheeling your gonna be doing. Mild offroading in construction sites is easily doable with the Dana 35, unless your trying to break it. Realistically decide what kind of wheeling your gonna do, if any, and then build around it.

If you try to stick to 3" better invest in some significant bumpstop extensions.

I'll agree with the 8.8 and 33s resulting in a very low hanging diff. It's not exactly terrible, but it is quite annoying. I put my 8.8 in about a month ago, and I plan on getting 35s ASAP but in the meantime I'm stuck on 33s. My last trip to Rausch I was dragging quite a bit in the rocks. Elsewhere it doesn't really matter, but in the rocks I was very aware of it. I was thinking about shaving it a bit anyway because the 8.8 is just so big, but I think the rocks might do it for me before I get a chance.

If you can afford it, go ahead a build for 35s now.
