Im new here and i recently bought a 2019 sierra slt has the x31 package i been checking everything one it because like you said it fish tails with some bumps i thought it was tires since im riding on 285/60/20 mudtires ive lower the tire, even thought it was suspension issues got it aligned, but can you confirm changing the rear shocks helped? 

 

The alignment was fine, truck was practically brand new when that happened, no more than 500 miles. I also have 285/60/20 on mine. It was clearly a safety issue, I nearly ran over a pedestrian and had to do a VERY hard left as quickly as possible with both of my feet on the brakes to stop that from happening. I was going around 35 mph, that was unacceptable.

 

Others have said replacing rear shocks have helped. I didn't get around to that, I just stopped driving it and now I am replacing it.
