I just got myself a set of the Bilstein 5100 adjustable shocks for my 06 CC SE 4x4. Does anyone know how high to adjust the shocks so that I can run 285/75 BFG A/T's? Also, should I add spacers to the front and a leaf pack in the rear if the 285/75 tires along with the shocks?

I was thinking about doing a 1.5" spacer on the bilsteins set at 1". I don't think anyone on here has run the bilsteins set @ 2" max, at least not that I have been able to find.
As for fitting the tires, I have no idea. I want to say you will run into some rubbing issues, but hopefully someone more knowledgeable on the subject chimes in.

I ran 285/75/16 on 3 inches of lift and zero rubbing. Plenty of room. I would think 2 inches would be fine. You prolly will have to take your mud flaps off if you didn't all ready.

I then put on 2 inch wheel spacers and it was rubbing like crazy.

Bilstein 5100 levelling shocks w/lift springs done.

I got some bilstein 5100 levelling shocks from greg at PRG and fitted them with 1.5in HD lift springs instead of the original springs.

I used the 2nd from the bottom ring on the shock body to mount the spring cup which is supposed to result in 0.5 inches of suspension lift over OEM with stock springs. I figured with 1.5in lift springs i would end up around 2inchs overall but for some reason i got about 3inches overall. The reason this is interesting is that i now have 3inches of front suspension lift with NO COIL BUCKET CONTACT due to the levelling shocks not increasing the suspension droop like a spacer setup does. :fantastic:

Even more interesting, is that ive only used the second from bottom ring on the shocks so there is another 3 notches above this that could provide even further lift however i will not be trying this as im already having wheel alignment problems even with the cam bolts i have.

I also had my adjustable bilsteins put on finally and they ride great, I didn't change the OEM spring out and I have the ride set at 1". Now I'm thinking if you like the ride with the new springs as well I might do it. What was the HD spring you got along with the bilsteins?

were you ever able to correct your alignment issues. I have the exact same set up as you and will be installing it tomorrow.

Thanx in advance for any help.....

Did you put on the bil's with stock springs? what ring did you set the bils?

I switched back to the stock springs and bought the CST Spindles was not happy at all with the angle of the UCA and spindle. I'm sure my rigs ball joint was not gonna last with the HD springs.

this is the angle of the UCA and spindle at stock this is what you want it to look like after your lift.

this is what it looked like with the 5100 bils and HD coils.. doesn't look good at all. It was set at the second from the bottom notch.

this is what it looks like with the CST spindles. It looks just like stock and the ride is like the first day I bought the truck..... Don't get me wrong I'm not saying the Bils with the HD coils is bad, I'm just saying that it was not for me, and I wanted to lift it correctly.

Oh, and yes I was able to align it with no problems.
