It's a little stiffer, but I like the feel better than stock. I felt like I had too much bounce with the stock setup. Probably going to replace the UCA's sometime in the near future to correct the angles. I went with the Falken Wildpeak AT3W tires. Spent hours reading reviews and couldn't justify spending $100 more per tire for KO2's.
2015 Sierra SLT. Just installed a 2.5” RC leveling kit and 275/60 20 on stock 20” rims. Probably could have gone bigger on the tires but wanted to play it safe.
