I know the K2 guys have one of these threads so I figured we should too. Think it’d be useful for others. Post pics of your setup! Make sure to add specs of the wheels/tires, spacers, suspension, rubb

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

      Some Assembly is Required

      By Grumpy Bear · Posted

      www.enginelabs.com/news/what-i-learned-today-bearing-clearances-vs-oil-viscosities/     www.enginelabs.com/news/oil-viscosity-can-the-numbers-be-misleading/ The Big Lie… Coming full circle to the reason Lake discusses the Porsche engines in particular. Based on the 2000 samples in the SPEEDiagnostix database, increasing the oil viscosity in these engines, even those run on the track, showed no significant difference in results.   The smoking gun was in the oil chemistry. That is where the data shows higher instances of more wear. Molybdenum was the key; the higher the amount, the less the wear. Speed postulates that higher viscosity oils have more thickeners to artificially inflate their viscosity numbers. These thickeners lose viscosity under shear, and the result is that not all oils of the same viscosity have the same shear stability.   Having enough viscosity is the most important characteristic, but according to Speed, once that required viscosity level is reached, additive chemistry matters more than additional viscosity. Speed also states, oil pressure problems on the racetrack aren’t a viscosity problem; it’s an oiling system problem. Running a thicker oil is just a band-aid for an underlying oiling system problem.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled II?   Viscosity on the decline by various means. Heat on the rise making that worse. Engine RPM in the tank. Smaller motors with more boost trying to emulate an electric motor. Full torque, zero rpm. Then we will triple the OCI. Argh.    But wait....there is more. LSPI has pushed a shift from Ca to Mg and as that cost more PLUS the run to lower sulfur compounds the TBN is moving in the wrong direction for the increased OCI's demanded.    That not being enough to placate a demand for a parameter they can't measure the other sulfur bearing compounds are also under attack. That would be zinc and phosphorus sulfonate compounds. To some degree those are being replaced with boron esters and others, i.e. titanium ect. All of which have shorter service lives. And there there is the "Secrete Sauce" marketing for AW adds that 'Can't be detected by UOA's" but trust me because I (the blenders) never ever lie.    Spoiler alert; ALL additives are sacrificial! Smaller amounts of the old blended with less robust versions of the new do not equal longer service lives. So what are the blenders recommending? Wait for it.......   MOVING THE GOAL POSTS! OMG      Let's declare the long standing TAN/TBN crossover irrelevant and tell people that soot is a great 'graphite' based lubricant which can aid tribo films. Wait, what? Let's declare that the standards used for oxidation and nitration were to conservative and can be expanded. Let's tell them that because GDI fuel dilution, although being a VISCOSITY KILLER and an acid generator is actually okay because we have better base oils that limit viscosity failure limits. (Said knowing this is measured in fractions of a centipoise and in bases not commonly used in shelf oils)   Lying from the heart is not just the new normal but we have a public, a very young public, that is so ignorant of the facts and so sure of their "RESEARCH" into AI driven models base in regurgitated  instead of scientific research based unvarnished, peer reviewed FACTS that the incoming guard is loosing their grip on reality and the OEM's are tickled pink while the blends bend the knee.    You have an ever limited set of tools to work with. And sooner or later those will be taken from you as the API and the EPA strangle the last remaining fluids from the system. What you have left is your wits. If you care to use them.    At some point in the very near future it will not longer be possible to do "What is best for the machine", and be replaced with "The best you have access too". You WILL be rewarded with half the life and twice the cost. That isn't that hard to predict.

      Software Update

      By Chuck FB · Posted

      I trust you saw the other comment where he knew what he was talking about !. Yes, these darned newer vehicles with all their so smart they are stupid technology, goes and drains the battery down. As you might see my other comment, I installed a Noco 5 battery tender under the hood and at this point still have the cord routed so I have to lift the hood and then plug it in but am typically parked in a garage or a shed so its not risking the engine hood in the wind. That way I am assured or hopefully so of not finding I have a battery drawn down and can't even start the truck and that also damages the battery to draw it down too far.

      Software Update

      By Chuck FB · Posted

      I guess no surprise my guesses were wrong !, at least now I know if I ever happen to see it grayed out in my own truck as to what is going on.    I never happened to catch my truck with it grayed out, it seemed every time I would test to see if there was an update it never found anything and yet more than once I would check to see if there was an update and there was nothing, then a day later or even that same morning I would drive to town and after more than one engine shut down in town as I did my errands it would pop up that there is an update now ready to install and the only place I have a connection to the internet is at home by wifi so its not as if it grabbed the download while driving. I don't trust these new vehicles due to all the crap they can decide to do while sitting for some days not running and run the battery down so most of the time if I know the truck will sit for a few days I plug in the battery tender I have mounted under the hood and so the only time the truck must have downloaded software was when it was sitting in the garage where the signal is awful but I have that tender plugged in and somehow it managed to download it. I honestly detest all this crap, way to easy to leave a person stranded.    Since I don't trust any of it I don't do the install of the already downloaded software until I get home and sometimes have even sat in the truck to watch what its doing as its going through the process to its conclusion as its not like it is set up that it will tell you the next time you fire up the engine that the update that was initialed actually installed or installed properly. Yes I can go into the updates and see the list. After I go through the install where I feel its safe to do so in case it breaks down as a result, I will plug in the battery tender after the fact to recharge as I don't know how much power its taking just to do the install and that can take a while for it to install.

      Thanks for the reply. All settings were correct and the engine was off, as it was supposed to be. It turned out to be something simple. I took a drive for about an hour. I must have had a low battery without knowing it. The voltage gauge on the display looked ok. At the end of my drive, I shut off the engine and the update prompt came up and it updated normally. It’s ironic because one of the features of the update is a reduction of battery drain.
