I had a 14 Silverado 5.3 short box LT 4x4. Procomp 6”. The lift is solid. Never an issue. Only gripe is the sway bar link ends reused factory and had sharp angles. Other than that the lift was perfect. Powder coating held up for 150k miles before I traded. I pulled the spacers at 130k and replaced with RC Vertex front and rear res shocks. Stock ride was good but it rode like a tank. Rear shocks were horrible. I replaced the factory front struts at about 70,000 miles and went with pro comp pre-runner struts and they were worse than factory. Then when I put the RC coil overs on the ride was just as bad if not stiffer and I had the preload all the way as low as it can go and got the height that I needed by using a leveling spacer.
Long story short the lift is solid, the shocks suck.
Technically the same lift but I’ve noticed a couple of differences like on my 14 my CV axles were nearly straight but now on the 17 they are probably 15° down angle to the wheels and my upper control arms are perfectly straight. Looks to me like in the later models they changed the transfer case and front differential bracket and now there’s a lot more angle which doesn’t allow you to lift it a little bit higher if you want to add a level kit. The wiggling passenger seat is gone though.... On the 2017 I have the Pro-comp front coil overs and I am extremely pleased with them in comparison to the RC Components coil overs. This truck feels far better than my 14 did. There appear to have been some changes made to the Lift in general just in the way that it appears, they added brackets to add to your sway bar to try and adjust the link angles and there are a couple minor fabricating differences, but they don’t appear to make much difference in the stability of the lift.
I will say that I had issues getting the suspension angles to not wear the front tires on the 14 left and it appears that the 17 lift is the same thing. I tried couple different alignment angles on the old truck to try and compensate y running factory settings or running a zero camber or slightly negative camber and custom toe settings didn’t seem to help, the tire wear was exactly the same either way. Not sure if that’s a kit geometry issue or just a vehicle characteristic but it is a little frustrating at $500 Per tire.
Hope this helps.
