Re-gearing question

I been reading and reading for weeks about this subject. I'm finally taking my YJ to the shop to have it re-geared to 4.88s. I was wondering, is it worth it to put a locker in, if so, should it go in the D30 or D35?
This is my DD and I do minor off-roading here and there mostly trails to take the fam out and enjoy nature or to go huting up in the hills.
Some people in Jeepforum recommend a locker in the D30 and some recommend it in the D35 other say I don't need one.

I know most people will say, don't spend your money on re-gearing the D35 but from what I have heard and read. The D35 is not to bad as long as I stay with 33s and nothing bigger. I don't plan on doing any crazy driving since it is my DD.

So should I add a locker if so, where? and which one do you recommend.

Adding a locker changes the entire way your vehicle will drive/handle. I would recommend (if you can) to drive someone's rig that is locked and see how it feels. Also, for your type of driving (DD and 'mild' off-road) you may not even need one. Depends on how 'hard-core' you wanna get. I have had a locker in my other rigs, currently have open diffs. I like them both ways ... so really it's a personal preference.
IMHO - don't go for lockers just because "it's the thing to do"... do it when after you've been wheelin' a while and come home and say, "Damn, I could have made it if I only had been locked!" - then you'll understand why you truely need one. - my 2 cents.

Scott thanks for the reply!!
I do trails here and there and do enjoy going thru small creeks and stuff like that. I never go alone I usually have another car with us. I do get stuck in mud have trouble climbing small hills but i assume its because its a 2.5L and on stock gears. I know the re-gearing will help some with the hills but does it help with getting stock on mud? or should I lock it.

I don't mind getting stuck and getting recovered by my buddy or using the hi lift(for me thats some of the fun in offroading) but will a locker prevent some of this stuff.

Sometimes a locker will help and other times it will hinder a situation. If you are just doing mild off-roading, I wouldn't go with the locker Idea. They are designed for a more serious style of off-roading.

It's true about a locker making your vehicle drive different? Almost like you have to learn how to drive all over again? Not really. If a Spartan locker is working properly, you should never know its there when you are on the street. And if it's a selectable locker then it should be in the unlocked position anyhow.

I would think that once you got the deeper gears installed, the only thing you need then is a good air compressor, so that you can lower the tire pressure down when you are off-road, and be able to re-air them when returning to pavement. Makes a WORLD of difference in the traction department. And that after all is what you are after with a locker.

Thanks guys for your help.

You can buy a winch and a compressor and still have enough money left over to have a BIG party, compared to buying a locker.

Normal full case selectable lockers are around $1,000.

My winch was $299, and my compressor was $150.

You can get an automatic LOKKA brand locker (Lokka is the parent company of Aussie lockers) for around $198.00 for the D30 and $218.00 for the D35. That's including shipping. Just saying.
Heres their website

Wow the people that say you don't need a locker for anything but hard core wheeling must drive though shallow puddles and a call it wheeling. I can't tell you number of times on mild easy stuff- I can get though when it's dry out- that I have got stuck where one tire is planted on firm ground and then the opposite tire is just spinning like *LOL meme* 'oh you want to drive?'

Seriously? You are going to bust on me for saying that you don't need a locker? Geez, and this whole time I thought you were a nice guy. I will only say this, It is easier with a locker installed but for mild wheeling it isn't needed. If you need a locker for mild wheeling then I think you should learn how to drive before taking the machine out and getting it stuck.

[QUOTE=YJ-92;12621634]0II0forlife if that's the case ill go with a new front bumper as well. What kind of winch do you use? also what compressor?

I have a Badlands 12,000lb. winch from Harbor Freight. Some say NAY about it, but it has never let me down. Besides, it is the EXACT same winch as a Ramsey, or a Smittybilt, just has different stickers on it. They are all made by a Chinese company and then each company puts their own stickers on them. It ranked 2nd in 4wheel&off-road's winch test a few years ago.

The compressor that I bought was an ARB. Same compressor that is used for the ARB air actuated lockers. 12V, 4.7CFM. I have it plumbed into a tank with a pressure switch. When the pressure goes down, the compressor kicks on. Will fill my 4 tires in about 10 minutes.

Lol. I didn't even read your post; I stopped reading right after Scotty's and where said something like 'don't get a locker just cause it's the thing to do, or everyone does it, or something like that. Which is ridiculous, there's a reason people install things like lockers (things you can't see) vs a million light bars. Sorry you took offense to it there guy.

I just read you post and agreed with what you said. You can get but without lockers with a winch.

And I guess the term mild, hard core, easy, etc is all relative to the person speaking..but if you don't need a locker at least a couple times on a mild trail then you're on an easy trail IMO.

Open diffs suck. Especially, if you live somewhere that has a lot of clay in the mud.

That's my point, just didn't say it right. Most of my modifications are an 'evolutionary' process ... I wheel it, learn from experience, modify and fix what's broken, then wheel harder.
The first Jeep Jamboree I went on, a guy had a really nice Wrangler with ARB Lockers front and rear - he just crawled over everything - very impressive, but was there any skill or was it just a drive in the woods? However, watching a guy drive thru a rock garden with open diffs, maneuvering and placing tires in right place, etc... -That's Impressive!
Point being, Learn that you need a locker, and why, first.

10 min for a $150 compressor is not too bad I have seen people take about 20 min airing up on the trail. After my re-gearing is done i will start looking for the compressor.

I just checked the link you send me for $500 I can lock front and rear its very tempting but I think I will hold out for about a year or two and then add them if needed.


I also hear that D35 locked will break real easy on 33s How true is this?

The stock D35 has been known to break with 31's, open differential, on the street, just driving down the road.

People say don't spend money on regearing the D35, because it is likely going to go kaboom later. Even more so likely if you put a locker in it. Not a matter of if, but when it will explode on you. Even upgraded shafts are no guarantee that the axle won't snap.

Google "dana 35 snapped" to see what carnage you can expect.
