JK as DD?

OK friends I'm thinking I want to get rid of my nice(ish) car and my 98 TJ 2.5 and sort of flip flopping them. Get a JK and a cheap car to drive to work. What does it take to get a JK on 35's to be good on the highway and off road?

Ideally I'd like to be able to take road trips to go wheeling in Colorado or wherever I find as there's not much of anything around here. I'm thinking I'll be better off in the long run since the JK won't take so much to make it look, drive, and perform the way I want. With my TJ I would have to trade out the engine, tranny, TC, axles before it's even worth looking at lift, tires, armor, etc. I could see the TJ working fine if I could go wheeling nearby but at this point even driving 2 hours away is a little scary. What do you guys think?

JK/JKU Rubicon with 4.10 gearing off the lot can run 35's with a 2.5" budget boost. Gear ratio means fairly decent efficiency, 16-18MPG highway but YMMV.

You can go from a simple budget boost at low cost to an expensive suspension lift with control arms, springs etc, or anywhere in between. Depends on how much you want to spend and where your tolerances are for handling and ride quality.

My $0.02....

Last year I traded my 2011 Challenger RT Hemi 6 spd in for a JK sport 2dr 6spd soft top. I added a 2.5" lift, 35" tires bumper and winch and couldn't be happier. My wife, 7 yr old son and I regularly take it on 3+ hour trips without issue and it gets around 20 mpg with 3.73 gears. I think you will be very pleased with a comfortable, reliable JK as a DD. I know I am.
Last weekend I beat it up pretty good at Rocks and Valleys breaking the rear fender flare loose due to tire contact and running it close to the headlights deep in mud/water and then drove home about an hour with no concerns. Washed it and it looks new again to drive to work Monday.

Eh mpg varies widely from jeep to jeep because of many factors. I'm very easy on the skinny pedal and I am at 12-14 mpg with 4.10 gears and 35's....

Awesome that's what I was looking for. I'd probably be looking for a little older JK as I'd be wanting to stay in the $15-18k range but I'm assuming they are pretty similar to the newer JK's (?). The new 3.6 won't be an option unfortunately. The good news is I've driven my 2.5 with stock gears and heavy 33's so I don't think anything will ever be as gutless. It has 31's now which are a lot better.

Huge difference between the 3.8 and the 3.6. When I jump out of my Rubicon and into my wife's 2011 Wrangler I feel like I'm going from a sportscar to a scooter.

Heh Heh, thats interesting--when I get outta my '08 JKU and ride in my buddys 2013 JKU/w 35s--

I notice the trannys shifting faster, but thats the only difference-

He gets 18/19 mpg on the freeway and I get 18/19 mpg mpg-

OP if you're in the 15/18k range--you will have trouble finding a decent mileage JKU, maybe an '07, but the 08/09/10 are sticking in the 19/25k range--

I've seen new 3.6l deals at 24K for a 2013 JK, kinda basic/w few options-

Good luck

Jim is correct on the price there. Minimum with decent mileage are around $19K, typically for a 2 door.

As for 35's on a 3.8L, you think your TJ is a slug now, just wait. I needed 5.13 gears in order to make me happy again.

Our 3.8 on 35s is no slug, but the very first mod we did was swap in 5.38s. Will you be happy with it, maybe. Just be prepared to spend money to make it go, or just shell out the cash for the 3.6.

Just my opinion, yours will differ.

I would get some used Rubicon take off tires, 19/60 springs and quick disconnects. You will be very surprised on what JK's can do stock.

lets be clear, the 3.8l with an auto tranny and a manual tranny are two completely different beasts from what ive experienced. i have friends with both, and the 3.8l nanual with 3.21s still feels better than the 3.8l auto with 3.73s. both jeeps have 35s, auto said 14mpg, manual states 16-17 (just what they tell me). that being said ive also not dd'd a 3.8. but i have two 3.6ls. one with 3.73s and 35s. then one with 4.10s and 37s. first jeep got 16mpg, and my current rubicon i average 18. i think im rambling now

Can only speak of my experience. My 2008 JKU is my daily driver. running 6speed manual with 5:13 gears and heavy 37" Toyo O/C mt. Last year I added a RIPP SC more for my trips to the NC mountains as I haul a 3800 lb camper but didnt need it for daily driving. I also run a sprint booster Throttle response module wchich gives that little extra kick. I couldnt be happier. my gas mileage is 14mpg in town and 16mpg on highway if I behave.
