kev324 I got some parts today:

Wheels: American Racing AR172 Polished Baja 16"x8"
Tires: Pro Comp Radial Xtreme A/T LT315/75R16

I'm still waiting for the Teraflex 2.5" coil lift and Bushwacker flat fender flares to arrive.

kev324 I wanted to go as big as practical for a daily driver. Big tires just make obstacles seem smaller. For me, 35s were an easy choice. I'm hoping that I don't regret it. The Duratracs seem very popular. But, I've also heard great things about the Pro Comp Radial Xtremes. I guess I won't really know what to expect until I get everything installed and see how it handles.

TOK Hey Kev, I have a 2013 Sport, but its a 6 speed. I have my 2.5" Teraflex lift sitting here, waiting on wheels (FedEx tracking says 7/9). I also spent a lot of time reading, flip-flopping between 33's and 35's. Ultimately, I decided to go with 35" Goodyear Duratracs. They run just a little bit small for a 35, but they are also one of the lightest tires of that size.

I hope there are no issues, but I figure if worst comes to worst, I'll sell the 35's while they're still almost new and get a set of 33's. My Jeep will see mild off-roading, but will also be used on 3+ hour road trips a few times per year.


Some tires that size are E rated, which means they are going to be super stiff and like 10 pounds heavier per tire. Thats a huge difference to be spinning at highway speed.

kev324 I'm almost embarrassed at how much time I spent researching my build. But, after countless hours, I've completed my parts list:

Extreme Terrain Teraflex 2.5" Coil lift with shocks TER1251002
Extreme Terrain Jeep JK Flashcal PN. 3570
Extreme Terrain Rugged Ridge Exhaust Spacer Kit 17606.76
Town Fair Tire Custom wheel and tire package
American Racing AR172 Polished Baja Wheels 16"x8" 5x5 4.5"BS 1726873
Pro Comp Radial Xtreme A/T LT315/75R16 PCT56315
OC Auto Access Bushwacker Flat Style Flares 10919-07
Ace Engineering ACE JK Pro Series Rear Bumper with Tire Carrier ACEJKPSRBTCFL

Please feel free to share if you think I'll have any problems with these products.

I've ordered everything except the rear bumper / tire carrier. I was ready to order directly from Ace, but the shipping is $148, which doesn't seem fair. They also needed 6 - 8 weeks. I'm hoping that a vendor on here can do better.

OC Auto Access is selling the Bushwacker fenders for $150 less than most places. This seems too good to be true, but I decided to take a chance on it. The part number is correct.

This is the fourth time that I've deal with Town Fair Tire, and I have to say they are great! I searched the web for the best price on wheels and tires, printed up my results, walked into Town Fair Tire, and they were happy to match the price! They aren't even a Pro Comp distributor.

kev324 Thanks for the help, michiganadam. I've only bought the lift and exhaust spacer. I haven't bought wheels or tires yet. I'm back to the drawing board again. I did the math on the 16"x10" (4.5" backspace) wheels, and they will stick out (away from the vehicle) 4.25" past the stock wheels. This seems a little extreme to me, especially for a daily driver with the Dana 30 front axle. I don't even think the Bushwacker flat fenders would cover them.

I still want the Eagle Alloy 058. They make a 15"x7" on 5x5 with 4" backspacing. Do you think I could mount a 35x12.5r15 tire on a 7" wide wheel?

I'm thinking of ordering 1 to check for fit. There are Ebay sellers advertising this rim for Jeep Wranglers...

It would be great if this setup works because this is the wheel I want, and I can get 35" KM2s for a 15" wheel for around $245.

It seems like most people run 16"x8" wheels, but eagle alloys doesn't offer this size on a 5x5 pattern.
They have a 16"x10" 5x5 -24 Offset with 4.5" backspacing. Is this what I want? I'm assuming that these will stick out 2" more on each side, but I am going to install the Bushwacker flat fender flares. Does anyone see a problem with this setup?

What tires are you running? As long as your tires are wider than the wheels, it'll *work*. Hell, lots of tuners have wheels that are wider than the tires and it still works, looks stupid as hell if you ask me though.

I run cragar soft 8s in 15x8 (4 inch backspace) with duratrac 33x12.5s.

If your tires are 12.5 inches wide, on an 8 inch wheel, that means the sidewall will balloon out 2 inches from the wheel on each side. Gives it an aggressive monster truck look in my opinion, which looks cool. It also potentially protects the wheel from damage, you're not going to just rub crap against the wheel as easy.

If you have a 10 inch wide wheel, the sidewall is going to balloon out from the wheel an inch. Won't look "as cool" (but 12.5 inch wide tires always look cool so....)

The 10 inch wide wheel will actually perform better though. You'll get more of the tire in contact with the road, on an 8 inch wide wheel you'll have 4.5 inches of tread thats basically not supported by the wheel. It'll curve away from the road at any normal tire pressure. But it'll flatten out when you air down.....

As far as if it'll fit the jeep? That's still an issue of backspace. You'll still want the same backspace you would want with an 8 inch wide wheel.

15 inch steel wheels will probably require caliper grinding, but tires are cheaper in that size.

Barmanvarn I'm running the TF 2.5 coils with Billstein 5100s and duratrac 33x12.5x15. Gears are 3.21.

I drive on the highway all the time and I feel like it drives and handles fine. Same goes for trails and back roads.

Just my 2 cents.

Cue my spiel:
I had 3.21s. Bought 35" Toyos- panicked after reading all the bad news about 35s and 3.21s. Returned them for considerably lighter, smaller 305/70/17 KM2s. Drove for about 3 months- and wasn't happy. I agree- 3.21s and stock tires are great- it won't feel like that afterwards. Whether or not it bothers you is ENTIRELY subjective but there is a performance difference. It doesn't bother some people at all- but many wind up re-gearing. A pretty penny. And you'll never see 21 MPG again.
In the end I paid for new gears- and afterwards I bought "true" 35s. You could save yourself the hassle and possible $$$ and just buy 33s.
That said- I've had about 5 people in the last week (since 35" install) tell me how good my Jeep looks. Just random people that walk by. So you can just say "screw it" and look good. Albeit maybe slowly.

michiganadam My jeep has to downshift to go over an ant hill and i know it wastes gas doing this. Atleast you have the pentastar...

ohioviper TF 2.5 spring lift with Rancho 9000s and 33/12.50/15 Duratracs. 2013 3.6/auto with 3:21 and happy camper.It is actually quit peppy but if I went to 35s or larger a gear change would be in order pronto.For what its worth I didnt do the exhaust spacers and so far drive shaft looks fine. I am considering doing discos and extended brake lines so then possibly will run into exhaust spacer / drive shaft issues.
06-06-2013 07:07 PM
kev324 I have a 2012 JK Sport S with auto and AHT, but mine still came with 3.21s. I actually don't mind the gears for now, with the stock tires. After 40k miles, I've never felt under powered. I average 21mpg.

My plan is to go with 35s, a 2.5" lift. I'll only re-gear to something like 4.10s if it feels sluggish. I like gears on the high side with an automatic.
06-06-2013 06:57 PM
michiganadam Hell i have 33s, 3.73, auto, 3.8 and its such a dog. Planning on 4.88s but had a friend say, what? Never go more than 4.10!! Im like wtf? Even if i had 40s? Yup, basically. Heheh. Honestly theyre geared too high even stock...

No people that are satisfied with 3.21 have no clue and never have driven a similarly built JK with 4.10, 4.56 etc…I was quite content with my 3.73 and 35’s but as soon as I put in the 5.13, WOW, what took me so long. Granted mine was the doggy 3.8L but 3.21’s suck on any platform. The 3.6L benefits from 4.10 and 4.56, even 4.88 for some.

With 3.21 you lose final gear (shouldn’t be acceptable, ever) crawl ratio etc…

derf My 2012 Sport S came with 3.21 gears and the larger tires.
06-06-2013 06:31 PM
Daniel_M Sport S should have 3.73 right?

Anyway, you should be fine. TONS of JK’s from ‘07 to ’13 start at a 2.5” lift. You are no different. You will be fine. The only thing to consider is that exhaust spacer thing for the ‘12+ models but other than that a good 2.5” lift kit would suffice. Shouldn’t have to mess with caster or driveshaft issues. You may also want to consider 4.56’s.

06-06-2013 06:21 PM
JeepHerz Do consider your gear ratio with 35s if you go there. 3.21s can be sluggish. What is your current ratio? I have a 3" Mopar/TF lift with 35" KM2s and 4.56 gearing on my 2012 JK 2 door. Love my Jeep but I rock-crawl and trail. I need all the lift I can get to compensate for my bad driving. IMO as a DD only I'd stick to a 2.5" or less, slap on some 33s and call it a day. You avoid driveshaft issues, balancing issues, weight issues and it still looks good. (You see taller lifts on 4 doors because they're larger rigs- a 2" lift doesn't seem to do much visually.) Make sure you're looking at realistic expectations of lift based on your 2 door and any armor/winch etc. you'll be running. Any lift company should be able to give you a good approximation based on your set-up.

michiganadam Big tires will do worse in the snow on the street. Offroad is the reason to get them.

Get a heavy duty damper, stock can barely even handle stock tires.

offset is the opposite of backspace. I have 4 inch backspace on 15x8s, tires are duratrac 33x12.5. They lock up under hard braking more than goodyear wrangler st (st for street tire lol), which arent even good tires. But i did not hit the two fools who had just wrecked in front of me so whatever..... guy passed a guy at the same time he was making a left turn lmfao neither used signals.

They also ride worse than stock tires. and it is my daily driver. I just dont care.

Leveling lifts that remove factory rake can cause excessive hood lift. 2.5 inch with 33s is where its at. I have an 08 auto with 3.8 no driveshaft issues at all with the 2.5.
06-06-2013 04:19 PM
Greg__Berger What spring rates do you have right now? I'm actually looking for a buyer on my 18/59 springs and Rubicon shocks off of a 2013 Unlimited. Depending on what rates you currently have, you could get an extra 2"+ out of the springs I have.
06-06-2013 04:06 PM
kev324 Do you have any issues with driveshaft vibration? How does the driveshaft clearance look while under the Jeep?

I was already leaning toward the TF 2.5" coil lift. Is there any reason that you wouldn't recommend it?

I feel like the 35" tires will help enough off road and in the snow to justify the decreased mpg.
06-06-2013 03:40 PM
mcgee10 I don't know why you would go this way for a DD on the highway most of the time but.
Mine has a teraflex 2.5 lift with Rancho xl9000 shocks. Mine is a weekend toy driven very little on the highway, mostly trailered. Mine has 33" tires on 17" wheels and does very good off roading and duneing . 2.5" lift and 33" tires and your mileage goes to hell my mileage is worse than our Suburban. But hey it's only your money do what you want.

Lifting a 2-door / Auto / 3.6L

Has anyone installed a 2.5" lift kit on a 2-door / auto / 3.6L? This seems like the hardest setup to lift because of the driveshaft / caster issues.

I've had my 2012 JK Auto for two years. Now that it's paid off, I want bigger tires and a lift. This is my daily driver, and I do a lot of highway driving, so I think 35" tires / 16" wheels with 4.5" offset make the most sense. To fit these, I'm leaning toward the Teraflex 2.5" lift kit with shocks. I'll also install the Bushwacker flat fenders for some extra room.

I don't want to "cheap out" here. I don't mind spending $2k on a lift. But, it seems that most 3-4" lifts are geared for JKUs. It seems like every JK I see with 4" of lift has the manual / 3.8L.
