I have an 01 xj with a 5.5" Rubicon long arm lift :) & I just changed the rear axle to an 8.8 & relocatated the shocks which are now way 2 long. How do I determine the correct size for the new shock & where can I find a Bilstein dealer?

I have my Jeep setup at 4 inches uptravel.(Allow 4 inches of the shock shaft exposed).

I run the 5150s but I am also sitting higher I got them from 4wheelparts.
Came across this today for rear shocks http://store.jksmfg.com/merchant2/merchant.mvc?Screen=SHOCKMOUNT&Store_Code=JKS01&Category_Code=Shock
its adjustable

Thanks fellas for the moment I am going with a shorter shock & will build something close to the JKS mounts to accomodate a better travel.

I was thinking about building my own. the price seems a little high.
Send some pictures if you make one.

Will do, it does look like a great idea. I am getting a set of 5150 shorter shocks today to get buy for now.

Darn I have 5150 fronts and 5125 rears. Hoping to sell within the next few months when i can get some new ones.
I really like them they work Awsome. But I need a resivour shock.

Crash are you desert racing? My understanding is that the reservoir's pretty much carry extra fluid just to help cool the shocks when they are put under extreme stress conditions such as desert racing. I stay pretty much to the rock crawling which does'nt build much heat & actually I probably get more heat when I drive it on the highway.
I also ended up with a 5125 & now have a set of rear shocks that will fit a 5.5" to 7.5" lift according to Rubicon Express.

You would be amazed of how hot the shock will get just driving 20mph down a dirt road. Drive 2 miles down a slightly bumpy dirt road, and then get out and grab the shock.

Pretty easy to make a new upper cross bar. Here's my setup. Less than $20 in material and about 30 mintues to make. The bar is welded to 1/4" plates that attach where the bumpstops are. I run 10" travel shocks with 4.5" uptravel.

I was thinking about doing this same setup for my axle swap when you get a chance to test it let me know how it preforms compared to stock. Was there any that I should know about this setup before hand I will probable set mine up wider to allow room for my four link.

Its pretty much a hybrid can go 50 through the whoops but not to long because the shocks heat up fast or down a dirt road I have only jumped it once but I need to truss my axles before I do it again
but I also like going through the big rocks nice and slow.

WOW getting some great responses here. I have installed a set of 5125 Bilstiens with a 13" body for the time being & they seem to be working well, will find out today as we are going to try them out on Upper Ajax for starters.

What part number you go with? looks like I may have to change my shocks

There's more to it.

I actually converted my emulsion coilovers to external reservoir so that I could monkey with the gas pressure. If you decrease the gas pressure in an emulsion type shock, you increase the propensity for foaming and shock fade.
