I haven't had that truck or any parts in about 4 years.

I used all OEM parts and everything worked perfectly.

Here is my truck. 3" Cognito Premier leveling kit with 37 12.50's and stock wheels. Had minor trimming on the liners and the mud flaps. The biggest issue is the stock wheels will make contact with the Cognito upper control arms at full lock, so I had to add a 1" wheel spacer and then everything was perfect. I was never a fan of spacers, but as long as its not too big its not bad, the biggest thing is getting a quality spacer that is hubcentric. I had absolutely ZERO vibrations at any speed range Not sure if the stock wheels would contact the control arms on the RC lift or not. I was told by Cognito that I couldn't run 37's on stock wheels with their kit, but I chose to buy what I wanted and make it work. That may be what you need to do as well.

You'll have more luck in the "mods" sub-forum. I had the 3" Cognito on my AT4 with 37's but I can't remember what the overall lift was and I sold the truck. But why not wash it yourself? Automated car washed are one of the worst thing you can do to your paint.

I love the Ram infotainment personally, but i'm a sucker for huge TV's, computers, tablets and so on. But, Ram can keep everything else about their truck.

Actually, Nitto makes a 37x11.50 which actually may give you all the room you may need. I didn't know they had a 11.50 until I had already bought my 12.50's. But I still think the spacer bringing the wheel out some completed the look

The inside of the tire rubs the Cognito control arm at full lock real bad, the rubbing on the liner was minor and easily fixed with very little trimming. But the tire/control arm rub was so bad that the inside of the Ridgegrappler would grab the metal control arm and almost bring you to a full stop. Theres no way around running 37x12.50's on the factory offset wheels and the Cognito UCA's unless you run the spacer. Cognito told me from the beginning that it wouldn't work but I figured i'd risk it and find a solution. If i had it all to do over again I wouldn't change a single thing. The ride quality is truly unbelievable and everyone that rode in it couldn't believe how well it rode.

It still stayed pretty tucked. Honestly I think it made the stock wheel and 37" tire combo look even better. I've always been anti spacer too, but with this one being hubcentric I didn't have a single vibration or anything. There was another user here that tried to use a cheaper spacer and it vibrated, he then swapped to the one I use and his vibrations stopped. I did have to trim about a 1/4" off my factory wheel stud, but the last 1/4" isn't threaded anyways so you're not losing any useable thread.

Will you be running your stock wheels as well? And 37's or 35's? I had 37x12.50's but keep in mind that I had to run a 1" hubcentric spacer in order for the inside of my tires to clear my Cognito UCA's when at full lock. If you plan on aftermarket wheels then you'll want to do your research on an offset that will clear everything. Good luck and post pics when its done.

This is 100% false! The shops that say " oh i'd never run a leveling kit" most likely only deal with people that want to spend $300-$500 on a kit and then expect it to ride the same or better. I was that guy a few years ago. I had a 2" leveling kit on my last truck that cost like $150 bucks and it rode like garbage. But, I can tell you that my Cognito set up rides like a freakin dream and i'd put the ride quality of this kit up against any "proper" lift kit on the market. After my leveling kit nightmare, I spent 5k on my last truck suspension and it had Fox coilovers with the external resi's and that kit rode way better than the leveling kit, but it rode like a log wagon compared to the leveling kit on my 2500. There's a reason why a Cognito leveling kit runs north of 2k with the Fox upgrade vs all the other's, and its because of the amount of R&D they put into their kits. You get what you pay for. If someone is cheap enough to skimp on the suspension of their 60-80k truck, then they will get exactly what they deserve when it comes to the ride quality.

You must be 70 years old with bad eyes if you think 20% is terrible at night. lol

I can tell you that you won't be disappointed with the Cognito level/lift. Not sure if you're going with the Premier kit or not, but i'd highly recommend it just for the adjustability (external reservoirs). I had mine adjusted right at the middle setting and its just crazy how much better it rode over stock. I also ordered a 1.5" rear block when I ordered my Suspension MAXX diff drop just to keep a little bit of rake. I think I had about 1/2-3/4 rake once it all settled.

I haven't researched it much, but I do remember seeing a guy on YouTube who deleted his 2020 Denali. I think it's been pretty reliable for him. I think it's DennyDiesel on YouTube

Mainly due to work being nonexistent for me. I've been in the music industry for 15 years and covid has 100% shut our industry down. Haven't worked since Feb 2020. Luckily they've kept us on salary but not sure how much longer that will last, so i'm preparing for a worst case scenario. Plus I had close to 20K equity in the truck so I figured it was the smart move since it wasn't my daily driver.

LOL tell your guy at the shop he doesn't what he's talking about. I clearly ran 37's with ZERO issues once I trimmed the liners and flaps. But i also had stock 20's
