I have a 2007 Commander Sport 3.7 QT1 that is my daily driver. It now has 115,000 miles on it and needs a new suspension. Rather than just go replacing with stock struts, shocks, and springs; I am thinking it is time for a lift.....I will be due for new tires by this fall anyway.

So, I have pretty much settled on getting an Old Man Emu (OME) suspension lift, but am stumped if I should go with the HD or the MD option. This XK is my daily driver (about 35,000 miles a year) and gets me from trout stream to trout stream towing my drift boat and a couple of buddies with our gear. I won't do much wheelin' in it other than getting the boat down to the river on two-tracks and forest service trails, but want to be somewhat off-road capable (had a couple of times last year where i didn't have the clearance and would have appreciated some rails).

So with all of that background, could you help a brother out with the following questions:

1. HD or MD OME Lift for a 3.7 QT1 XK?

2. Recommendations for a good all-terrain tire for highway use?

3. At this point, I am going to stick with the stock wheels, what size tire would you recommend with this lift?

4. Should I upgrade the Upper Control Arms while I am in there?
(If so, i was thinking of going with these Rocky Road UCA's...any thoughts?)

5. Will I need a trim package still to level my XK after the OME install?
(If so, I was thinking of this one)

6. Will I need to buy any additional items for the install such as a strut mounting kit?

Thanks for your help / input. This will be my first upgrade, so I am excited and nervous. Once i get this put on, if anyone is in the STL / Ozark area and wants to get together to test it out, drop me a PM.

OME HD for sure. While your at it replace the coil isolators front and rear (there are 8 total, 4 front 4 rear) as well as the front upper strut mounting plate. I bet your front sway bar end links are probably shot if you haven't replaced them yet. As far as a good AT tire Good Year Wrangler Duratrac and get some 1.25 wheel spacers! Would look awesome! If your getting new upper control arms get the new JBA UCAs

Not a problem. I wouldn't steer you wrong. You will love your Jeep after those mods. 265/70R17's for the tire size or 245/75R17

I just did the HD OME and it rides great.

Like 07JeepXK said, I had to replace Strut mounts and Isolaters.

They don't tell you that up front. Also you should replace the mounting bolts.

Thanks for the responses 07JeepXk and cico7. Are wheel spacers that big of a deal? I really didn't want to put wheel spacers in or go with a ridiculous tire size (and effect the fuel economy i am getting....close to 18mpg), but wanted it to look beefy enough. Will i notice much of a difference in look going from stock and 245/65/r17's to an OME and 265/70/r17's or 245/75/r17's?

If you are concerned about gas mileage, stop right there.
The lift and tire size individually will drop your mileage 2 or 3 MPG.
I average about 14....total avg. 15-18 Hwy only 10-12 City Only

You will need spacers if you go to 265 70's Wider stance looks better anyways.

Summer time I get better mileage than winter.

Nah, not concerned with mpg....just more curious what the drop will be. Getting ready to order it now.

Get the UCA's. I got the JBA's through 4X and they are red.
I say ok because I have nothing to compare them to.

I think Rough Country offers them for about $100 less. I dont know what the difference is, if any. But I was on a roll so I got them all at once.

Using the HD parts will give you about 3" of lift. From the center of the hub to the bottom of the fender is 22"

I too average 14.1 mpg but I'm running 33 inch mud tires on 17x8 steel wheels that are heavier than stock wheels. I don't mind getting that mpg because my jeep looks bada$$!! JBA is definitely the way to go for upper control arms if you don't mind spending that much money on them. I love mine and have had no issues with them and I even have the old version.

The Deal Is Done....The Parts Are Ordered

Happy Birthday To Me. The Old Man Emu (OME) Lift Kit (i went with HD) along with some JBA Upper Control Arm's for the Commander have been ordered and the new coils, struts, shocks, and Jeepin' By All UCA's will be here in about 10 days or so. I have a fishin' buddy that is a gear head and is a full-time car/body guy that has access to a lift that has agreed to help, so things are looking promising.

Now, where is a good place to get a Haynes / Chilton's / Service Manual style book (or pdf) for the XK?

Nice purchase! You will be more that happy with that setup. All you need now is a Rustys rear adjustable track bar and you will be set!

Lift, UCA's, and a few other things showed up at my office on Friday. I still need to order an adjustable track bar, and need to add tow hooks to the front. I have a friend who is wanting to tackle this next weekend, so hopefully pics soon.

Lift is installed. Definitely need to get the new tires and an alignment done asap.

I think I want to stay away from wheel spacers at this time. Current tires are 245/65 Cooper Discover ATR. What will give me my most bang for my buck without a spacer and no rubbing?

Pics to come.

Lift Is Installed

Thanks to a buddy, and his buddy with a car lift, my OME HD lift was installed this Saturday. The whole process took about 7 hours or so. It definitely lifted the Jeep a solid 2" + and leveled it out.

2007 Jeep Commander Sport 3.7 with Cooper Discoverer HT (245/65/17) and OME HD lift installed

I will have photos with the new tires installed tonight or tomorrow. I went with Cooper Discoverer AT/3 in 245/75/17. More photos coming.

OME HD and Cooper Discoverer AT/3 Installed

Here is a little better photo of the OME HD and Cooper Discoverer AT/3 (245/75/R17) installed. My speedometer is off by about 3mph and my MPG has dropped by about 1.5mpg (although I expect this to change).
