Install Bilstein 5100 shocks on the front, at the highest setting and adjust the height sensor at the rear.

 

how do you adjust the rear air suspension settings? pics for video please? Just installed the 5100 with raybestoes front HD springs PRG rear spacers.. rear sits a bit lower than the front.

 

The sensor for the rear height is located on the driver side, behind the rear axle. Look at the attached drawing. To raise the rear loosen the two mounting screws on the sensor and rotate it CCW to raise the rear, or adjust the ling to make it longer. You will need to have the engine running for the system to adjust. There is a delay, so you will need to have the engine running a few minutes after adjustment for the change to take place. You will hear the compressor run.

 

Wow, thanks for the tip. Got a 2" rear lift in 30 seconds.

 

cool thanks!! well another issue. I had a missing sway bar bolt so i switched out the bushings for new ones and put the bolt back in.. now i have a binding sound coming from the front when i turn almost full lock... any help?

 

Are you sure you reinstalled the bar properly? The links at the ends of the bar must be vertical, going down from the bar. When the bar is removed the ends can rotate down out of place. Also there are flanges on the bar to keep it in the proper side to side location.

 

also i assume it is not common for this smaller lift to have interference with the sway bars?

I adjusted the sensor attached pic, but rear still wont level or pump up.. help?

 

 

The position of the adjustment rod is incorrect. Its supposed to be lined up vertically, not horizontal/parallel to the coil bucket.

Disconnect the bracket from the coil bucket and correct the position of the adjustment rod along with the pivot arm that connects it to the solenoid.

 

oh fyi the front from ground to top of fender well sits at 40" was at 36.25", rear has not changed at all still at 36.25" even after installing the PRG 2" billet spacers..

 

thats what i thought looking at the diagram... i wasn't sure if it was different on the QX i got the 05 qx56.

 

Primo nailed the problem. Link should be vertical as marked in red on drawing.

 

cool guys thanks!! that fixed my problem!! i'll be posting pics here soon on the rig. Looks sweet and rides much better than stock front suspension.

 

Making the adjustment to the ride height sensor, will it effect the ride or with towing? Can/Should you add 2" spacers to the rear? I have done a lot of reading on the different ways people are doing lifts but very few have switched the auto level out and from the little I have read it will cost a ton of money. I just want a 2-3" lift(front and back). I understand I can do the front easily but would like to figure out the rear with out changing out everything and dumping a months worth of pay just into that.

 

I did 2" in the front with Bilstien 5100s on the highest lift setting. They lifted the front to 38" at mid fender. They ride very hard, significantly worse than stock in my opinion.

I adjusted the ride hieght sensor to even out the back fenders to 38". Within two weeks the rears went flat and the compressor would run every engine start. If i drove more than 30 minutes to an hour at night, the healights would point way up in the air as the rear deflated and the compressor would stop running for whatever reason. On/off would pump the rear back up, make the headlights dangerously hard to adjust, especially with HIDs which are very aim sensitive.

I don't recommend doing the Bilstein 5100 quick lift for both of the above reasons: the 5100s ride way too hard all the way out, and the air suspension is leaky if the truck is 5-7 years old. I'm going to lower the 5100s to normal height and replace the rear o-rings, plus add 2" spacers all around. If I have to, I'll put 5100s in the rear.
