Yea the design of the shock on the front is called a strut, it comprises of a spring and a shock together. (used on IFS vehicles now-a-days).
The rear is a solid axle using a coil spring so it uses a traditional shock absorber.

Do you sell the Bilsteins? If not where here in the Phoenix area can I get some?

The WK uses a fron "Coilover" design,a shock with a coil surronding it.

Easy way to tell between a "Strut" and "Coilover" on a IFS(and/or IRS) vehicle is if you have a upper control arm you have a coilover,no upper control arm you have a strut.Struts take place of a upper control arm to place the top of the knuckle.

So when you guys upgrade the shocks/struts, are you replacing just the rear or both front and back? Anyone know the part #s for 2010 commander – want to put on bilsteins.

Rears can be done in your driveway with the tire jack in 30 min or less. I took mine in to the local mechanic to do the fronts since I dont have the tools.

I put Bilsteins on all 4 at once (not myself - no space to do that work) and the Jeep came alive! You can't go wrong - and Kolak is the best source to buy them from

My wife's 08 is at 100k miles and I'd like to do a suspension/brake refresh + GDE ECO tune. Just looking for more pep and a smoother ride. I plan to keep the stock springs and was wondering if the 4600 Bilsteins would be a better choice vs. the KYB GR-2's. She doesn't off road but does drive it very sporty like it's a Cayenne. I don't want to get under the car for another 100k miles.....

what do you guys think?

I don't know about KYBs but I have had the Bilstein 4600 HDs on our '98 ZJ for about 120,000 miles and they are still good. I installed them in May of 2002! I think for a WK, if you want to keep the stock rake then go with the 4600. The 5100 on the lowest setting (3/4" lift) will eliminate that rake and it will appear level. It depends on what you want. The ride of both is about the same.
OME is a different design shock, probably a bit better off road as its not as stiff and due to the twin tube design has a bit more travel than the Bilstein monotube design. They do cost more, close to 25/30 bucks more in the sizes we checked.

The Bilsteins are a high pressure monotube design and will offer ride control, responsiveness and fade resistance vs a low pressure twin tube design such as the KYB. You'll be very impressed with either the 4600 series or the 5100 series. Both are valved the same but the 5100 series has adjustable front struts to level/lift the Jeep.

PM me if you'd like pricing or just more information

Thanks for the feedback. I was worried that they would raise the car but it sounds like they won't. But still curious to hear from someone who has them on their original springs.
