Need some expert advice

Sooo, as of right now I'm driving a 2014 Jeep Wrangler Unlimited Sport. The most basic model. The only modification is 33" tires.

Now let me make myself clear that I am not even close to being an expert when it comes to cars. I can fill it up at the gas station, jump start it, and check/fill the oil, but that's about it. I've tried to teach myself, but there seems to be an awful lot to learn. As a Jeep owner, I have grown interested in modifying it more. I've started doing some harder off roading, but nothing exceptionally intense. But I digress.

I was looking to add a 4" lift with 37" tires. But doing my research, I saw stuff about upgrading axles, changing gears or pinions or something like that, and maybe extending the brake lines.

Now first, are all these changes worth it and/or necessary/mandatory to run this lift and bigger tires? Because I look to do a lot of off roading, but it's also the only car I'll be driving and thus will be seeing a lot of street use. Maybe even more often than off road at times. So should I go with 37s on that aspect.

Second, I'm not sure what going to Dana 40 or 60 from 35 means exactly or what 4.10 gears mean. Will these require more unwanted costs, because I am on a budget. Plus I'm not sure what the stock 2014 Unlimited comes with in terms of axles and gear ratios. It may already have the Dana 40. I might want to add that it is a 6-speed manual transmission if that matters for gears and such.

There's a lot to take in and it's a little overwhelming so I'm not sure if it's worth it. Please help! As you can see there's a lot, and maybe even more that I don't know yet.

Suggestions, advice and even questions I can answer to be more specific are all greatly appreciated.

Thanks.

What you are proposing is equivalent to an infant who just learned to crawl being entered in the Olympics 100m finals. Start slow, learn, and work your way up.

I'm still a newb and I'm taking my time figuring things out. I would heed daggo's advice. Don't be in such a rush. A 4" lift is a pretty significant change that will require additional modifications and costs will rise quickly. I'm still figuring out what my Jeep can do and letting it tell me what it needs. If you change things before you really know what you have in stock form, you're going to have difficulty in knowing if it's behaving correctly post-mod.

Just my opinion.

I realize it's a lot, but I would start off by reading everything in the lift section of the Tech Common Questions sticky. It's got a lot of great information.

Hahaha! I may have made myself sound a little dumber than I meant to. I have a basic understanding, just exaggerated a little I guess. Anything that comes along I should be able to handle, I'm just wondering what it is exactly that *will* come along. Because some things were talking about upgraded axles and such, and others said it didn't matter and wasn't necessary. Basically I'm looking for majority opinion. I see your point though. Lol. Thanks.

If you're out on a trail and run into a situation that makes you think "wow, if I made this modification then I could handle this a lot more easily and/or be safer", then the mod in question probably makes some sense.

If you're sitting at home behind a keyboard thinking, "wow, I need to make all these mods because everyone else is", then your reasoning may not be too solid.

Unless you're just interested in appearance or want to be one of the cool kids. Then it doesn't have to make sense.

Note I'm not offering any expert advice (since I'm not an expert), just a little common sense.

Definitely makes sense. Lately the trails I've been doing I have found myself needing some more clearance. Just how much clearance is necessary is where I'm stuck. I've now started swaying to just a little more than what I have now with a 3-3.5 inch with 35s.

As for appearance, I know the importance of it to some, and while I would enjoy the look of a nice big jeep with all the mods, it most definitely is not top of the list. I drove mine with the tiny bicycle tires for a good while and was fine. I just want something that will get me through what I want to get through. But of course, going higher means additional changes, and I'm curious to what the most important and absolute necessary of those changes are.

No matter what size tires you run you will always say "I want more clearance"-I hear that from folks on 37s and 40s too. Cuz you just drive over bigger stuff lol!

A 2.5 inch lift and 35s can get most folks most places. A 37 is only going to give you an extra inch or less clearance than a 35 (ie not all tires are "true"). That inch costs a whole buncha money to do right. Picking lines appropriate to your rig and more experience are absolutely free and may get you much further than that single inch. Simply dont try to take the same lines as bigger folks. If you are running trails that "require" 37s, you are into "all but guaranteed body damage and crunched metal" territory. The expense to get you on 37s will pale in comparison for all the fixing you will do on those type of trails lol.

This is not a budget friendly hobby at all lol. Suggest you do a lot more reading and get some more seat time just telling yourself "Ok I have 33 inch tires. How can I go around/over this obstacle differently so I clear?" instead of saying "I want to go that way but my 33 inch tires are too small so I need bigger ones".

A skilled driver on 33s will go further than an unskilled driver on 35s or 37s...just sayin.

Also look into joining a local Jeep club that wheels your terrain - they will be able to give you very specific help. And make good friends with some reputable offroad shops in your area!

What exact is your budget? Going above 35's will require a regear to continue normal street operation. If I understand correctly this will still have it's fair share of street driving, which is why I would recommend a 3.5" lift on 35's and I'm sure many other people would agree with that. With this size, no regear, brake line extension, adjustable control arms, etc. are necessary. Typically with the 3.5" lift, all necessary upgrades needed to run the lift will be included

Here's an introduction on why you want to change the gears in your axle when you go up in tire size: Regearing Basics

Here's an introduction to the different types of differentials and lockers without trying to sell you anything: The Basics of Differentials and Lockers


I agree with others. Take your Jeep out as-is right now and learn how to drive it off road. Building up a killer Jeep without having developed the skills to drive it properly can end in disaster. I started with a bone stock XJ Cherokee that I drove all sorts of places with no real modifications. Doing that first really taught me a lot so I can get the most out of my built JK without destroying it and hurting myself.

All the responses are greatly appreciated. So thanks.

As for experience, I like to think I've learned an awful lot. I'm not an ultra pro experienced expert by any stretch of the imagination, but I've learned. I have a few buddies that have owned Jeeps for years that I've gone out with and learn from.

The reason for wanting the clearance is that I'm not getting a very good breakover angle at some spots, preventing me from continuing or causing me to bypass, not lack of experience. I would think a couple inch lift would do me good keeping the 33s, but assuming I would want to go bigger I thought I should go ahead and get 35s now and not go any bigger. I've decided against the 4" with 37s now due to this being my main driving vehicle and not many super rough places that would require that where I'm located anyway.

So a couple inches with 35s shouldn't require any regears and such is what I'm getting, so that might be what I do. Unless anyone suggests otherwise. And don't worry, it's not like I'll be getting them tomorrow, just looking to upgrade soon.

Again, thanks for the help and replies.

Good choice :thumbsup: another suggestion is to get the rancho 9000xl shocks with the lift when it comes, not the shocks that come with the lift

If you have the base Sport with 3.21 gearing, you will definitely want to regear for 35s. If you are ever up Phoenix way and want to run some more challenging trails, shoot me a pm.

Noted, I've seen quite a number of people say the same thing so I'll take a look since it seems to be popular opinion. Thanks.

I do indeed have the base JKU. It's manual all the way around, including the windows and locks. Nice and simple. So if I do have to regear, would I go with 4.10 or what?

And thanks, I'll keep that in mind. A lot of the stuff down here is certainly pretty tame.

With 37" tires I'd consider 4.88 or 5.13 gears.

I have 35" tires and I really like my 4.56 gears. Bigger tires = higher number gears.

This is great advice.

Start by noting that a 4" lift with 37" is a big lift and big tires with big ramifications and unnecessary if as you state "you don't plan on doing anything intense off road".

Your Jeep is very capable off road with the 33" tires you installed. I suggest you drive for a few months off road, learn your limits as well as your Jeep's. It's a lot more capable than you are if you are new at this game.

Don't want to be a kill joy BUT you mention a 2014 JK and a budget 1st is to consider the warranty most of the mods you mentioned WILL void parts or all of your warranty. and 4in. lift and 37's is going to require other rather expensive mods and probably premature parts breakage not under warranty. You might consider just driving it for a while until you get a feel for it and then if you still feel the need use a much more conservative lift and tire size you really don't need or want 37's on a street driven daily driver

4" with 37". That setup done right isn't cheap.

Honestly I'd suggest doing yourself a favor and get out to a meet in your area. Otherwise its a long post on needs of something like that and probably won't touch on everything.

I plan on doing 2.5-3 to start off with 35-36's.. But later thinkin about 37's or 38's with all the proper gearing and strengthening.

Question is.. Is there a better route to go at first to have an easier transition into a 4-5" lift later on?
