Sorry for the delay,

 

Hard to tell if the ride is much different from the Tires or the Shocks.

 

No Noticeable difference in MPG. I think the tire weight of the Non-LT tires help (11lbs per tire lighter then the LT's, unsprung mass is bad for MPG).

Nitto is the only MGF the has a Non-LT tires in this size and the make both the standard and the LT in the same size so you have to be very specific on what you order. I got them from Discount Tire.

Thanks for the advice on the tires. I’ve seen the non LT but as you said, not in this size.  How do you like the Bilsteins?

Cooper rugged treks come in non LT, eibach pro truck struts are an option comparable to bilsteins, very happy with mine, 2” in the front, 1” in the rear.

I wasn’t aware. What size Cooper Rugged Trek are you running? How’s your ride with the Eibach struts? I mainly on pavement but definitely some off-road. Mainly mud.

275/60/20. The eibach kit has lift springs instead of just adding more preload to stock springs. The ride with the eibach kit is much better in my opinion, no more “porpoising” after big bumps or pot holes, you do notice smaller bumps more at lower speeds though.

Lots of non LT in the stock size 275/60/20 (33" tall) its the 275/65/20 (34" tall) that no one makes in a non LT.

 

Im happy with the ride of the bilsteins, better than stock for sure. I looked into both the eibach and bilsteins. they actually list the same way. They both have adjustable lower spring perch positions to set the ride height. The Eibach's do come with new springs but both the stock and the eibach springs are liner rate springs so to me it was hard to justify the extra costs.

 

For the rear blocks I called a local suspension shop and they gave me a set of blocks from the previous gen truck, they had a pile of them laying around going to scrap. They are 1.2" cast iron. 5 mins in the sandblaster and some black paint and they looked liked new. OE Ubolts from 2018 truck fit perfect.

There seem to be very few choices in non LT bigger than 275 60 20. Nitto makes a 305 55 20 ridge grappler in non LT that weighs 4 more pounds than your 275 65 20 so I’m pondering the choices. Post some pics after you install your rear block, please. I have less than 1 inch of rake so if I raise the front 2 inches I’ll need to raise the rear also.

I looked at the 305/55R20 but they are the same height as stock @ 33". IMO the height is needed in these trucks more then the width. I also have the 2.7L so un-sprung weight was important to me to maintain fuel economy.

 

I will post the pics with the rear blocks installed when I get a chance. I Ive been sidelined with a shoulder injury so it might be a little while.

The weight of your tires is what got my attention to start with. I’m concerned about mpg but also I messed up the ride of my last truck with heavy ko2 tires and determined to not do that again.

What’s up everyone, been a while since I’ve posted but I sold my 2020 LTZ and recently purchased a 2022 RST Z71 limited (I do not like the refresh personally). I put a leveling kit and 285/65/20 Nitto Ridge grapplers on the OEM 20’s. Minor rub so I removed the bracket and did some very minor trimming of mud flap and zip tied liner. No rubbing at all now.  Really impressed with these Ridge Grapplers. Ride like the stock tires.  Now I know why they’re so popular.

That's a good looking setup. Exactly what I'm looking to do. What leveling kit did you use and did it perfectly level your truck? Did you have to use any wheel spacers to clear the tires? Any other pics would be great!

Recently picked up my new ‘22 AT4 and swapped out the Duratrac’s for 295/70R18 Ridge Grapplers. Kept the stock setup and surprisingly have no rubbing even at full lock.

All stock 22 refresh rst 6.2 liter, s&b cai, Gibson cat back exhaust, 15% ceramic wrap, 50% ceramic on windshield and sunroof,  275/60r20. Measures 1.5 inches of rake. Might go to 285/60r20 but that's it. No leveling kit needed. I tow a boat and trailer and the tongue weight levels truck out pretty good

I'm also thinking about running a 285/60-20 when my wheels get here.

 

I just have a stock AT4 at the moment, but will most likely level it at some point. 

 

Hoping the 285/60's won't rub too much

    • I forgot to answer the question as per what market mine is set to and yes I finally found that area on mine and yes its also set to America.   So here's something I realized as I wasn't looking at that part in the Sierra section until now, your right that what I see here as choice 3 under Sierra which says 07/2023-06/2026 ( 433 MHz 13542523 ) it has no choice 5 for tire pressure selection. Where as it does under the Chev choice. However I kept going down the list within the Sierra and I am really wondering if choice 9 will work for your truck as it has the same model number and hertz sensor as my truck. I would say try that choice first, if that doesn't work then jump over to the Chev section and again choose that same model and hertz choice as for some reason the Chev section gives the choice 5 of tire type/pressure selection for going back a number of years. Could very well be an Autel thing that they just didn't get the updates all done properly under Sierra but anyway first try that selection 9 I suggested under Sierra and then go from there. 
    • Looking for this piece that holds the hose clamp in place. I have the hose clamp just not that other piece. Dealers and wrecking yards in my area will not sell just that piece. They want you to buy the whole air tube $100 +/- to get that $5 part.  that piece isn't molded to the air tube as I looked at my friends truck. It's held on by a screw and nut. I'm trying to put the OEM parts on the truck as the previous owner butchered things up installing an aftermarket CAI. It really looked homemade. 🤣 Thanks
    • Ok I missed that part that yours is a GM. The strange part is that the choice for year ranges and within the year of 2026 is different on the Sierra then on the Chev for some reason as I am looking at my tool at the Sierra choices. Now I am guessing you see as to your sensor part number as it may be different on your truck for some reason and a call to GM should get you the part model number of the sensors you should have as well as which MHz your sensors are. I know mine are the ones as per what I listed but there are other choices in the Autel and got me wondering if by some chance they put different ones in your truck. Having said that, did you try using each of the choices starting from No 1 and going on down the list, not sure if that would mean shutting off the engine each time and resetting the tool and going at it again each time. Also I thought of something else which may sound retarded but if there was some stupid chance that the chev choice would work. The reason I say that is that the Sierra is showing a range up to 06/2026 for the various choices of sensors it could be where as the Chev has one choice that has that 12/2026. By the way it is possible to not run the truck and you may know that as per not pressing the brake but pressing and holding the start button for a few seconds and it lights up the dash ( its called service mode ) but that sucks battery power and if it were me doing it that way I would be throwing on a decent sized battery charger before doing it that way as killing your battery won't make you happy at me at all !.    Like I say, just a thought to try the Chev choices if you have already exhausted the Sierra choices but first it would be nice to know for sure what exact sensor model and hertz your truck uses as I assume only those choices that mention the sensor would work unless a choice that does not mention the sensor model would somehow work. Its frustrating when one is trying to use tools like this without the experience of the tool and the vehicle, as I am sure dealer techs themselves struggle with it when starting out or a new model year comes along that is slightly different. 
    • I tried before I updated the scan tool just incase an update messed it up, but it never worked so I updated the scan tool and it still didn't work.   Only difference is I click on Sierra not Chevrolet cause I have a Sierra.   If I click on 2026-2024 I didn't have any option to change placard, when I click on 2023 it does give me the option but when I try to do it,.it says vehicle not supported!   I have my region or market or whatever it is set to America I think, is that what yours is set to?
    • Its just that it worked on 2024 trucks on this forum and my 2025 model truck, unless GM did something since that point to screw up access or Autel has a bad update. I haven't had need to use my tool since last year when I did the changes to the placard pressure settings and since then I updated the software on my Autel but have not plugged into the OBD so hard to say if I would get a surprise as well.    All I know last year when I bought the Autel I was warned to be sure to update it before I tried using the unit as they said who knows how long ago unit itself was actually manufactured as the software could be way out of date.
