Probably because of the way you set the system to slightly raise your truck from static. I have run the trimset twice. It seems to set the zero at wherever the truck sits static with a full tank and then compensates for sag.
I think it works ok when you’re at stock height but when you’re lowered you risk confusing it, idk.

…and with the shock extenders you shouldn’t have to do any mods to the autoride system from my understanding

The extenders are to regain 2" of shock travel. If the springs lower it 2", the shocks will still operate at their full range of travel with those extenders. If you lower it 3", then you'll only lose 1" of travel. If you never load it down enough to bottom out the suspension (anyone that does wouldn't be interested in lowering), you'll never miss that 1".

The ALC (Auto Level Control) uses the ride height sensors to adjust the rear when loaded. As long as the sensors are right where they are now after the drop, the system will be unaffected and it'll operate the same. If you drop it 3" and leave the stock link rods on the sensors, it'll think you've loaded it enough to squat it 3" and it'll air up the shocks to raise it back up 3", negating your drop and making it ride like a wagon. Those $20 shorter links get it close, and likely within an acceptable range. But, if they "work for a 2" to 3" drop", that's still a whole inch of variance. The amount of air pressure it takes to adjust an inch will be felt. As Mark mentioned, you can do the same (and better) by making your own for way cheaper.

All you gotta do is get the sensor at the same position it's in now after you drop it so the system never "sees" the drop. Just as mine sat at stock height, I used a silver Sharpie to make alignment marks. After the drop, I removed the factory link rod and rotated the sensor until the marks aligned with one hand while I measured the distance between the centers of the holes that the link's ball studs screwed in to with the other hand. I pulled the ends off of the factory link rods and cut pieces of 10-24 x 6" stainless steel all-thread rod to make the new link rods. I think I got the all-thread from Home Depot for under $2.

Here's that part of my drop: https://www.tahoeyukonforum.com/threads/growing-up-doesnt-have-to-suck.93510/post-1413884

The factory design raises the rear about .5" at startup. If you don't want it to do this, then make your marks with it "aired up" at that height. Just know that it'll ride a little softer in the rear.

Hey there :naughty:

Been snowy, icy and very cold here the last few weekends so no progress since I don’t want to lay on a wet, salty, cold floor :lol: this is at the top of my list, tho, so I’ll make time for it as soon as it’s above 40 or so and I’m not going to have melting snow dripping on me :D

Took a break from work and at least got the coilovers put together per the instructions. I think what I’m gonna do is put in for a day of vaca and dedicate that day to getting the install complete on the Burb. Figure a few hours in the AM to do the job and then the afternoon pictar taking and making sure all is fine and dandy :)
