Stabilitrak engaging after lift install

[Goatnola]

I had a 7.5rcx lift put on my new 2016 Sierra last weekend with 35's. Now my stabilitytrac and traction control lights turn on when making turns at slow speeds. The CPU must think my truck is about to flip over when turning now. Anyone with this issue before? I need help!

 

Here's another issue I've noticed also... Now I'm getting a bad vibrating at 65mph and up after the lift, was fine before. I'm really starting to regret this whole lift thing.

Replied in other thread but will say again. The Stabilitrac engaging is due to computer reading wheel spin. Your stock tires were only 32" tires and spun at a certain rate. Now you have 35" tires and they spin faster so at slow speeds the wheel speed sensor tells the computer there is a spin situation. Get a tire calibrator and set your new tire size. Make sure you measure your tires as they probably aren't really 35" probably 34.5" at least mine are so you'll most likely enter a metric size tire to ensure it is exact. (eg. 305/60r20 is a 34.4" tire).
