Which circlip setting on Billstein 5100's will level the truck?

Hey all,
I have a 2009 4x4 access cab, 4 liter, v6. Right now, I have Billstein 4600's. I'm about to install my new 5100's. Which snap ring setting should I set the fronts to, to level the truck? I will have 5100's in the front and the back. The back is stock; I don't have any lift kits on it. Thanks.

 

1.75"
Third notch from bottom iirc

 

Thank you. Glad I didn’t try the top notch

 

Top notch is 2.5"

 

What would I need to install in the back in order to utilize the 2.5 notch and make the truck level assuming I have a camper shell but no other load in the back?

 

We can’t answer that.
You need to measure from the CENTER of the wheel to the fender.

Do that for both the front and rear.
That will tell you difference in height front and back. Then add what ever the difference is to the rear.

 

Thanks

 

Say for example the rear was lower by 1 inch, what would I install in the rear to make up that difference?

 

1” blocks under the springs.
Or new springs to lift it 1”.

1” blocks are about my personal limit.
Anything over 1” and you should get new springs. It’s not a have to, but is a lot better option.

The further “up” over the axle the spring is, the more axle wrap you will get.

 

Add-a-leaf would be a cheap and effective alternative to a block too

 

I’m also using old man emu 2884 to replace the oem springs. Do you think that will add lift or should I still do the third notch up?
