Well i have a 285/65 R20 on stock 20's on a 2.5 inch front level, and a 2 inch rear level with very little rub.  The rub is so minimal in fact that i hardly ever notice it.  You can see the extreamly

The only thing I'm really worried about is the sway bar because it's easy to fit 275/65r20 on a 2.5 inch lift and the big difference between that and 35x12.50 is the tire width.

i bought my ridge grapplers right before they came out with the new sizes. i would love to have been able to get the 35x11.5. thats ok. once i wear these out i may take the level kit off and do a proper 4" lift and put 35's.

Do you have a tune? The only reason I got 33s is because I was told 35s would kill my 3.43 rear end. How's the loss off power?

I have the 3.43 gears in my 2015, and I don't have any issues with 35's on my truck. I also do not tow anything, but normal driving it is just as responsive. In my opinion this is not as much of an issue on the newer vehicles as is was on older trucks.

Hey all. I used this forum for my purchase so wanted to give input. Have a 17 Sierra with a 2.5 RC level. I was able to fit 275/65/R20 BFG KO2s easily with zero rub. Not sure you could go any bigger w/o lots of trimming.

3.5” level with 35x12.50 stock 20’s. 1/4” wheel spacers in the front. Nothing in the back. Only rub a little bit when reversing on uneven surface. No trimming done either. It can be done but would only do it on stocks because of offset issues on other rims. You would rub a lot more if I wasn’t on stocks.

Yes you can fit a 12.50 wide tire. You will scrub the sway bar at full lock but its easy to avoid and there was defiantly a big height change with the tires.

Why can’t I see the pictures. Smh

They will fit. I have a 2018 Sierra with a motofab 2.5 inch leveling kit. With some minor trimming I was able to put Nitto Terra Grapplers 35 x 12.5 x 20s on and the only time it rubs is when I am backing out of a parking space at full lock. I wish I had a picture but I have had the tires on for maybe a year now and have had zero issues other than some minor rubbing.

      Differential covers

      By RJL1 · Posted

      I just brought home a 2020 GMC 1500 Denali.  She has 53K miles on her and I want to change out the fluids over the next few weeks.  I see the diff covers don't have drain plugs.  Any suggestions where I can pick up front and rear diff covers with drain plugs?   Thanks,   Bob

      Ac not keeping up

      Well, the dealership got the compressor and installed it. Air at the vents seems nice and cold as it should be. The service manager said the repair has a two year warranty and unlimited mileage. Hopefully I don't have to use it. The dealership i went to was one where I bought my 2014 half ton silverado. In 10 years and 168k miles on the truck anything I needed done and two small recalls they were always very good to me. Not a huge dealer either. I think they treat people well because they want you to come back. I have dealt with a different dealer that was too big to care about an individual. Just my two cents.

      Multigate Connector Difficult to Connect Fully

      By Another JR · Posted

      Hi All, I operate my 2021 3500 SLT most of the time with the tailgate off and in a crate because I have a slide-in camper. However, at least once a year, I take the camper off and put the tailgate back on. Recently I installed the tailgate, but had a hard time getting the connector bail to swing to the fully latched position. The connector seems to fully seat, and everything works, but the bail doesn’t swing to fully latched position.  It swings almost there but stops and I am afraid to push it any harder.    Does anyone have any advice on cleaning or lubrication or anything else I should be doing?  i know how to properly operate the connector. During the time the tailgate and connector are off, i have a double plastic bag over the truck connector secured with rubber bands to keep it clean, but it still had some dust in it this time when I blew it out with compressed air. I didn’t want to spray it with anything other than air without doing some research. Thanks.

      There are a lot of spammer's that do that, quote something and add some commentary to make it seem legit, but modify the quoted text a bunch making sure when posted it's long enough to be "click to expand", and either immediately insert a spam link, or come back after some time and edit it to add the spam link.

      Hello @jaszr2 Do you have a link for the item? I put a replacement bumper on my truck and consequently had to relocate the shutters. I studied on them a while, and figured if you left a couple key blades, you could get most of the airflow with probably no throwing codes.
