Got the kit today and just finished putting it on... easy install, took me about 1 1/2 hrs taking my time and triple checking everything. I would be ready for a test spin except for the $&@$& staple I found in one of the tires while taking them off. Quick trip to the tire shop for a patch and we'll be rolling. Thanks Tony!

I just installed this kit on my '16 denali xl, and love the look from driver side as it has about a 1/2" of rake. However, the passenger side sits an 1/8" lower than the front, also looks goofy leaned from the rear. I have lengthened the passenger sensor rod twice now, making no change. Yes I have both sides isolaters, spacers, springs in correctly, etc. What now?

Different spring rates are used in front.

So go to store
Get 3 inch long 10x24 machine screw
Cut off head
Replace rear autoride link

Done

Different spring rates on each side in front? Front is exactly the same measurement, and I have added about a 1/4" to existing passenger side rod (turn counterclockwise ) yet made no change. In fact I think the drivers side may have gotten a 1/8" taller lol. How much longer does rod need to be to get 1/2" more ride height?

No gm used different spring rates in front which can vary 5/8 of a inch from another spring in front.

Like I said in rear do what I said and will lift it up enough. You do not touch front links

Am I right to assume this kit doesn't change suspension assignment? Or should we get an alignment after install?

If you drop rear no you don't need to do alignment

Ok, bought 3" 10-24 machine screw, cut head off and installed on passenger side. Now pass side lifted to 1/2" higher than front as I wanted, but drivers side is now 1 1/4" higher than front! I shortened driver side rod and it helped a little but still 5/8" taller on drivers side which is definitely noticeable. I checked measurement in other places too and it is definitely 5/8-3/4" difference. Also, compressor for auto level seems to run often now. Is there another adjustment? Seems to me the passenger side should be slightly taller to accommodate road crown, not the other way around.

Also, before drop kit, both sides were level in rear sitting at 37 1/4". Could the rear track bar have anything to do with this? I think its bushings are vulcanized so maybe it is making it lean?

i remove airlines so all air comes out of system and then check height. if truck is leaning (which 99 percent do to drivers rear) thats normal. You then can turn on the truck see where it brings it to

I ordered one of these kits over a week ago and the order still says processing. Card was charged immediately. Can't get a response by PM or email. What's going on?

It came today finally. I installed everything easily but it's 1/2" lower in the rear than the front and I'd really prefer it to be 1/2" higher in the rear so 1" higher than it is now. Can I raise it 1" by adjusting the auto ride links? Do I lengthen them or shorten them?

do you have spacers in? the plastic ones or heater hose?

i had saved this quote from some other thread here:
The ideal length for the sensor rods end to end worked to 3 11/16".
For every 1/8 adj. on the sensor rods changes the height 3/4".


so lengthen the rod ~3/16"

I used both top and bottom insulators and the spacer.

I measured all the way around, removed the rods, and lengthened them by 3/16" and the rear height didn't change one bit so that's concerning. I drove about a mile before measuring, does it need longer to compute? I guess I'll lengthen them again tomorrow and see if I can get it to move.

I might just be bottomed out on my rod length, my rods were only 3 5/16" after my adjustment tonight. I'll bump them up to 3 11/16" and see if I get a change tomorrow after work.
