Bilstein 5100 questions

I purchased the bilstein 5100's to get rid of rake/add a little lift and noticed that some people use them in the rear as well. Can anyone say that this is possible and okay? I'm not looking to lift the vehicle. Just need to level it out and my struts needed replaced.

I have the 5.7 and planned on using original springs in the front. Is this okay?

I also plan on replacing the rear shocks. What shocks should I use in the rear if I have bilstein 5100's in the front with stock springs?

What level should I put the front also?

I know this has been visited many times but there is so much information with people using aftermarket springs etc. and I didn't plan on that.

There will be no lift added in the rear from the shocks. It is totally possible to use them, but they would be better in a lifted application as the 5100 shocks have longer travel than the 4600s.

With that being said, no rear lift, I'd get the Bilstein 4600s. Run the front 5100s at the lowest lift possible or you'll be needing to lift the rear next.

I'm currently at 17.75 (F) and 19.75 (R) so my end result should be okay if I go to the lowest setting. Even the middle setting would probably leave me even. Has anyone tried to go for the highest ring and just evened out the rear? If so what were your results and what method is best to even out the rear with the 5100's in front and 4600's in the rear?

Thanks for your help Kurt.

It looks nose high @ the highest setting.

Middle setting would be fine with no rear lift.

I ran mine on the middle setting with a couple of extra spring isolators in the rear which netted me about .75" IIRC rear lift.

Stacked 2 additional spring isolators in the rear and set the fronts @ 1.5"


Gained 1/2" rear and 1.5" front as far as I can tell so it sits pretty level. No spacers, as the wheels are +10 offset (18x9 with 5.39" backspacing IIRC)

Check out on of my posts with pictures. I used the lowest setting and the vehicle is leveled out and dead even. I'm thinking it might settle about 1/2" because I used new rubber spring isolators. I used 5100 all around with Kolak's recommendation.

Keep in mind, according to the 5100 instructions the front will be lifted approx. 1.2" at the lowest setting. This, I've found true.

I have my jeep lifter2 inches all around but my rear isn't sitting as high(rustys springs). I have skyjacker shocks for 2" inch lifted commanders. Would the 5100 rear shocks help with that? Or would load levelers be better?

the only rear shocks that add any kind of lift are the load levelling ones with the spring built in.

basically all lift kits "level" the vehicle. Since in the XK the rear fender opening is smaller than the front, when the vehicle sits level the fender gap is smaller in the rear. This is typical.

Some people run monroe load levellers, some add an additional spacer (usually a cut down one), I stacked some extra spring isolators.

That is a common misconception people seem to have about Bilstein 5100's - by themselves, they absolutely will not raise your ride height in the rear whatsoever, they are not designed to add lift, they are only shocks.

If you want to raise your rear end, the easiest way to do that is by installing different springs that are designed to add lift or you could do as others have suggested and give the load-levelers a shot.
