Spacers and blocks only and you will be fine. If you were going more than 2", then grab the TB axles. I have a 21 RST that I lifted 1.5" front and 1" rear using Bilstein 5100's. My front axles still sit level. 60K on this setup and no issues at all.

If you can fill the threads on an open ended lug nut (about 3/4"), then you are good. If not, read this:

So, just a quick update. I've had these tires on my truck for a little over 2 years and I'm right at 40,000mls. The tires have held up well. I measured the tread depth and it's 9/32 (new is 12.5/32), with nice even wear. I do rotate them front to back at every oil change which is 6,000mls. The shoulders of the tires have been rounded a little, and the road noise has increased ever so slightly (still quieter than any other AT tire out there). Traction is still excellent in all weather conditions, with the exception of some rear end slip when it just starts to rain. Overall, I am still happy with the purchase and would buy again. For now, I think I can easily get another 20,000-30,000 out of them.

Sold Pending Funds as of 6/5/24.

Pulsar LT, excellent condition. I had it on my 2021 truck for 10,000mls and it worked as advertised, flawlessly. I'm returning my truck so up for sale it goes. Includes original box and everything it came with, instructions, etc. You will need to provide your own Velcro tape to mount it. $300 shipped and insured. I'll take cash, check, money order, or zelle.

Are you sure about that 4-5 mpg? I put on 305/45R22 Hankook Dynapro AT2 Extremes and only lost 1-2 mpg over 20,000mls since I had them, and they are much more aggressive than the Michelins. Edit: You have a 6.2 and I have a 5.3. Not apples to apples. -

Read this:

2021 5.3, 8spd, 4x4 59,000mls Lifter failure bank #6 @ 26,000mls.

And the power curve.

Punch it when traveling at 75-80mph, let me know what happens. The 5.3 takes off like a rocket, the 2.7 falls flat on its face. I test drove both extensively before buying. Again, if you're a city/local driver the 2.7 works, but that's where it ends.

If you are concerned about clearance issues, just stick with the 275/50r22. It is 33" while the 285/45r22 is 32". The 10 mm width on the 285 isn't even noticeable next to the 275's. There are a bunch of new offerings in 275/50r22 as of late, including AT tires and the Michelin LTX MS. So far, anyone that has put the 305's on their truck has had no clearance issues. Even with the Sierra's, which have less clearance with the squared off wheel wells.

305/45 is the way to go for the factory 22's.

The 285/45 will give you less sidewall height. The 22's need more sidewall, not less. Unless, of course, you're looking for less sidewall? -

I'll take it! PM incoming.

I wouldn't drive around if you don't have a least 7 turns on the lug nut. Better yet, just test fit it for the look and don't drive around. It's not going to drive any different with spacers on it, if that's what you're worried about.

Why don't you take your 1/4" spacers and double them up on one side to see how it looks?

Did you get those new u-joints installed? If so, did it solve the problem?

I would look at the U joints. How do the front hubs feel when you spin them? How about the CV axles?

Interesting. How much does that tool box weigh? I got exactly 1.5" of front lift from installing the Bilsteins. The weight of the tool box might be compressing the front end that 1/4".

So you added 1/2" more rake to your truck? 2" rear lift and 1.5" front lift? The blocks are flat. The axle might be bound up a bit depending on the angle of the axle when the u-bolts were tightened. On a flat/level surface I would loosen all 4 U-bolts, bounce the rear of my truck with my body weight, then torque the U-bolts to 85lb-ft. -

20,000mls now and they are still solid. Still quite, still smooth, still have great traction in all weather conditions. Wear is nice and even, and they are still in balance. I'd buy them again.

Probably because the 2019"s are only due for inspection this year. My 2021 inspection sticker is good until 2026. But I think you answered your own question - the DFM was deleted in the software. -

What about all those Silverado's and Sierra's that were delivered without working DFM? I'm sure they will pass.

Just curious, how much DEF did you go through? And how much does it increase your cost per mile?
