Yes 2015 6.2L 8 speed

I have a custom 3" kit. I have the issue too. Nothing to do with abs wiring or anything like that. Also nothing to do with tire size conversion as I have HP tuners and my speed is 100% GPS corrected. I've tried doing a steering angel sensor and yaw sensor calibration and yaw sensor calibration with no luck.

Mine is not a 6" it's a custom 3" level/lift. With bilstien shocks.

I have the exafct same problem. Found it's mostly left hand turns that are atleast 90 degrees when doing them with a little bit of speed like turning from one road to another without a stop sign.

Its close to a 2.5. Bilstiens in the front at .75 with a 2 inch spacer and the 1 inch rear spacer added.

Few pics of my truck

Finally got a chance to wash my truck with the new rims. 20x9 fuel beast 20 offset 295/60r20 toyo AT2 extreme. Rides awesome. No rubbing with just tying back rear of front inner fender.

RC 2 inch spacer and bilstein at +.75 in front and RC 2 inch block in the rear and bilstein 5100. Love the set up. Rides awesome. 100 times better then stock ranchos.

Here's the truck with the new rims and tires and the custom rc/bilstein level. Still need to wash it. haha

Sorry about the crappy cell pics and how dirty the truck is. First nice day here in the great white north. Will take some more pics tomorrow when I get my new rim and tire setup on.

Just did a custom leveling kit. RC 2" Spacer in the front and bilstein 5100 struts at .6 lift. And in the rear I used the 2" RC block and bilstein 5100 shocks. The truck rides 100% better then stock Rancho Shocks. Smooth and controlled over bumps and that stupid hope the rear end used to do is now gone. Front end is 39.75 and rear is 40.75. Super happy with stance and ride. Would recommend this setup.

I've been waiting for my beast wheels for months. DAMN!!!!!

It isn't any different. I've done about 8 trucks of this gen and never had an issue or had to undo a ball joint for any bottom spacer. Just got to make sure both wheels are off and both sway bar links are loosened off all the way.

All you have to do is loosen the sway bar bolts. You will be able to pry the control arm down enough. I did my RCX 2" this week and it was pretty easy. No need to touch ball joint, tie rod or upper strut bolts. If you undo both sides before you attempt to install the blocks that will help as the sway bar is connecting both lower control arms. Love the look of your truck BTW. They have to be the best factory wheels GM has ever come up with.
