That's going to be a tall SOB for a daily. You also realize that is a spacer lift, you will be using 8" strut spacers on top of your stock struts. Also keep in mind this lift will increase your front track width 1 1/2", so you will need to run rear spacers to line up front and rear. Not a bad thing since you plan to run your stock wheels, that will help with a wider stance. Your going to need that going that high. The truck pictured looks to be running a 12" wide wheel which is typically a -44 offset. With a wheel like that and 35" tires an 8" lift is required to clear them.

Are you leveled at all ? That will make a difference. If not the +18 would be the safest bet. Personally I would do the 0 offset just to get a wider stance. The +18 will be very close to stock and the 0 will put you pretty even with the fenders. I had 20x9 0 offset with 285/60/20's with a 2" level on my 2018. I had just a slight rub on the carpet liner when backing up and turning full lock. I just zip tied my liners back and that pretty much stopped it.

You can run 35’s on the CST 4.5” with stock wheels. You may get a little rub on the sway bar due to the positive offset. But you would clear them otherwise. Sent from my iPhone using Tapatalk

I'm think the Superlift is a better choice if your looking at 6.5" just due to the full 6.5" crossmember drop. I know a member on another forum running it on his 2018 Silverado and it is a quality lift. Personally I didn't want to go that high on a daily driver that I do work out of the back of. I went with the CST 4.5" bracket lift with the CST coilovers which actually gave me 5" of front lift. I preferred not to increase my front track width. I run a 20x10 -19 wheel and a 305/55/20 for my Summer setup. That gives a nice stance without running any rear spacers. I can also swap back to my factory 20" LTZ wheels for the Winter. Also the CST 4.5" was designed to run a 9" wheel with 5" backspacing to allow a 35" tire. I just preferred not to run a 35" tire and stay closer to a 33"- 34" tire. This is my 2018 with the CST 4.5".

I sprayed Fluid Film in the tubes before plugging them.

All your lifts with a crossmember drop have cutting involved to allow for the front differential to drop. But I do believe the Superlift is a full 6" drop crossmember, which would allow better angles. The Zone 6.5 " shares the same crossmember as there 4.5" kit. Zone just uses a longer strut for the 6.5" kit. So in reality the Zone 6.5" angles are similar to running a 2" level on your stock truck.

Have you looked into Reklez UCA’s . That’s what I’m running with my CST lift. They have a serviceable sealed ball joint. They are are built in your home state. I have no complaints with them, been running them for 10K miles. https://reklez.com/ Sent from my iPhone using Tapatalk

Nice, I had those same wheels on my 2013 Sierra. Wish I would have kept them. Ended up buying the chrome 20x10 Hostile Rage wheels for my 2018. Sent from my iPhone using Tapatalk

Thanks, it’s a 4 1/2” CST bracket lift with CST coil overs, rear is stock block and Deaver J1 mini pack leafs, CST street series shocks. Wheels are 20x10 -19 Hostile Rages with Nitto Ridge grapplers in 305/55/20. The Ridge Grapplers are the lighter version, 52 lbs. compared to the E versions 62 lbs. I wanted to keep my 6.2 performance. The ride is very nice and an improvement over stock. Sent from my iPhone using Tapatalk

I had Reklez UCA's with stock 20" LTZ wheels and Fox 2.0 coilovers on my 2018 when it was leveled. I was running a 285/60/ 20 tire also. Look into Reklez , as beefy and nice as cognitos. I'm now running them with the CST 4 1/2" lift.
