Depends on the lift and also depends on personal choice. I have a 4 1/2" CST bracket lift, so no track width increase. No spacers needed.

However popular lifts like the Zone or BDS 4 1/2" are knuckle lifts, so they increase front track width 1 1/2" per side. I would say most people running a knuckle lift,  add 1.75" spacers to the rear to even front and rear trackwidth.

I was just curious as to whether people ran spacers after they did their lifts. I have read that you need a 1.5" spacer on the rear after adding a 4.5" lift to compensate for the front track width being wider.

Personal preference. Like said above, some lifts will add width to front and not rear due to being independent front suspension. So you'll front tires will stick out further than your rear tires. It bugs the hell out of me when i see this on the road so i would definitely add spacers if it were me.

Awesome guys. Yeah that's what I've read, just wasn't sure on spacers because I know it's a lot of wear and stress on a vehicle 

Not the best but Not so bad as long as they're torqued right and not huge spacers. Also make sure your studs are long enough to get enough threads on the lugs nuts.

      I have a 2022 Silverado 1500 four-wheel-drive. The dealer ordered the 2 inch lift kit they offer and I’m waiting for it to come in and have it installed. But I noticed that the kit doesn’t come with upper control arms. Is that going to be a problem?
       
      (***UPDATE*** )
       
      so I had the factory lift gm offers installed. When I picked it up, it looked great but as soon as I went to drive it off the lot. I could tell something was wrong it felt completely different. I figured it was just a break in period. But even after a day or two, I was getting crazy bad vibration at low speeds. Took it back. They ended up putting one of the U-bolts on wrong (I have pictures if wanted) they fix that and told me the vibration was gone. I get my keys go to drive away vibrations right back. I turn right back around. this time they have a mechanic ride with me. He clearly hears  an feels a vibration, says somethings wrong so we turned around and he takes it back in. Three hours later they bring my truck back they had to remove the back blocks said there was no taper to them and it was messing up drive line. I got it back and the vibration is still there. (Now annoyed that only the front is lifted and still vibrating). I have them take the whole lift kit off. Put it back to stock. (Now remind you my truck has been down and I’m missing work for 5 days at this point) And after that Whole ordeal, I was done with the truck since I couldn’t have it how I wanted it and decided to trade it in and they made me a good deal on a 2023 5.3 LT.z71
       
      I know many have gotten this lift installed said it worked out for some reason it did not for me. I’m much happier with the new truck.

      I have a 2022 trail boss lt that has about 6100 mile on it now. Bought it brand new in may 2022 and it seems like the drivers seat leans to the left towards the door. Almost feels like Im gonna fall out of it and no matter how I adjust it it seems the same. Visually it looks like it sits level and is fine. Is it possible something is broken inside like the frame? I would assume the frame would have to be sturdy. Is there any place that sell a better bottom cushion?

      Hello all, My Sway bar was hitting my CV axle, as the title says. So I crawled under some trucks at the dealer to see what stock trucks are like and it turns out that the new TB/AT4's have longer end links then my 2020 TB. The new end link has a 3 inch rod vs the 1-3/4 inch OE part.
       
      The part number for the longer end link is P/N:85590925

      I’m looking for the best 6 inch lift for this truck. I talked to a local suspension shop for an install and they spooked me on Rough Country - they stopped installing them due to poor quality and many after install problems.
      would very much appreciate any and all input - truck is a brand new build and I want to do it right.

      Hello everyone. I've recently purchased a 2020 Silverado 1500 from a dealership. I found out late in the sale that the truck was used as the dealerships "loaner" which didn't really bother me even though I know people beat up those vehicles. Anyway, I'm pretty in-tune to vehicle sounds and I had a couple of questions regarding noises I'm hearing from my vehicle. 
       
      The first is a clunking noise and a physical jolt when I shift from Drive to Reverse. I have my foot on the brake and am on a flat surface. I notice it a lot after I've been driving for a while and go to back into my garage. I took the truck back to the dealership and they chalked it up to bad U-joints. They slapped 2 fresh sets on, but I've still go the issue. Any ideas what it may be? I don't feel like anything is going to fail, but I also don't like the sound and don't think it should be that way. I have another service appointment next week and I'd like to help them out with ideas considering they don't really seem to care.
       
      The second is a ticking noise coming from the undercarriage. I' got under the truck today and believe it's coming from the rear portion of the engine, but I'm not for certain as I've never been beneath the truck while it's been on a rack. The noise cannot be heard when standing at the front with the hood up, but I can hear it very noticeably when standing at the driver's door. I do not hear it as the engine is heating up, but that could be because every other component under the hood is loud as h*ll while the truck is heating up. Once the engine is approaching operating temp, it's very noticeable. As you can hear from the short video, it's every .5 to 1 second or so and is always present during idling. Again, may not be a big issue, but I hate hearing things on my vehicles that I can't attribute to something else.
       
      Thanks for reading my ramblings. I can try to post longer videos if anyone needs. Thanks in advance!
