My boss has a Yukon Xl with the 6.3 (?). Idk the year but it’s fairly recent. He used to wrench on his own and takes good care still since he knows how to identify good/bad work. The lifters on his ground up right around 100,000 and sent debris into the engine. His favored shop said they could replace everything they found scored but were hesitant to warranty it unless he let them pull it all apart and blow all the passages out, which was basically the same labor as a full rebuild. He went with a jasper reman.
 
Uhh have you seen the ZR2 Silverado they have coming? If you want a half ton with some extra clearance that thing is gonna be sweet! Also you can just do your own lift kit setup on top of whatever trim combo you want. Factory trail boss is a nice modest factory lift, and i like factory, but it is no ZR2 or aftermarket. My recently sold 16 GMC 6.2 had a really good BDS coilover lift and its handling of bumps was impressive.

The latest generation of cylinder shutoffery may not be as reliable as the 2016 i had. Mine worked great but it was just V4 or V8 modes. V4 and a 40 mph steady road would yield really good MPG readouts like 35+ if you drive on roads of that speed a lot.

My next truck, if GM, will be a 6.6 HD. I can yield some MPG for durability.
does anyone ever actually need more ground clearance? i go back 50 miles off the hard road on forest roads on the north idaho/mt border every hunting season in a stock 2500hd with dinky 245/75r17 tires. never have a clearance problem. what i do need is a chainsaw and tow strap for clearing blown down trees off the road and snow cables in case a storm blows in. i used to think a lift would be nice but honestly can’t see a need? and if you don’t need a lift in remote north Idaho, where the heck do you need it?
 
yeah but then it has to be installed after the fact

with TB, it's already factory installed

and there's more to the TB than just the level/lift as well

what else does the TB offer besides the appearance and the lift? Some 32” Duratracs? Sweet.
 
We got a 2021 Z71 Suburban with the 5.3 for my wife a couple months ago. It has a 5/21 build date and has 4,000 miles on it so far with no issues. She loves it and it rides so much better than the 2017 Yukon XL Denali we got rid of. I thought we’d miss the 6.2 that the Denali had but the 10 speed makes up for it some and it’s not bad.

2500s are higher from the factory. My 1500 lifted about 4.5” looked very similar to a 2500, maybe slightly higher. The half tons are quite low for fuel economy.

There is also the point of it just being a want instead of a need. I would be more than happy with the current HD trucks as they are plenty high.

All Trail Boss models feature engineering that proves helpful when roads get wild and winding. Both include a two-inch suspension lift, giving the more clearance, and Rancho monotube shocks that maintain balance when the going gets tough. The LT Trail Boss includes dual-outlet exhaust integrated into the rear bumper, a feature that is available on Custom Trail Boss models. A high capacity air filter, Hill Descent Control, skid plates, and automatic rear locking differential help both Trail Boss models maintain their composure in mud, rain, rock, and more.

Man, google is hard. ;)

hey man, do what works for you. i think lifted trucks look cool. i used to think lifts had practical value but i have come around to thinking that for 95% of us, a lift only has cosmetic, not practical, value.

I've smashed both running boards on my F150 to the point that I pulled them off because they were so crooked that I would slip on them if it was wet/snowy.

But yes, I agree, for most people it does not really matter.

Ohhh wow. Rancho shocks? The pinnacle of suspension technology?

I take it back. Its a true automotive marvel. I am sure you cannot get skid plates and locker on any other Silverado trim. Especially on the RST with Z71 or diesel offroad package.

i had some fun in Grand Escalante years ago. Didn't need a lift but I did learn a thing or two about running highway tires on a dirt road with a sign that says "road impassable when wet." Went to bed thinking you couldn't get stuck with four wheel drive, woke up after an overnight rain and found out that the road was, in fact, "impassable when wet."

Ey dawg, I don't make the rules. Just giving you information, jewnose?
 
Impossible to say at this point since its only 7 months old with 4k miles. I am picky about the fuel I run and will likely run some fuel system cleaner going forward. I do like the power and the lack of AFM is nice. So far I am impressed.
Considering all the issues I had with the LLY Duramax in my last HD truck, I have nowhere to go but up.
Thanks. It does seem like a pretty nice engine so hopefully it will be durable over the long haul.

They usually know what they are doing when they put up signs like that. Nothing personal-but people not following rules are making the National Parks, Monuments, etc., even more restrictive for the rest of us.

It depends entirely on the trails one attempts to drive. I have a pretty capable 4wd with larger-than-stock, more aggressive tires than it came with. It's adequate for the trails I want to drive. It couldn't even attempt some of the extreme trails out there, without incurring major damage.

My stock 4wd Dually would be even more hopeless.

Right tool for the job.

i‘m guessing you don’t wanna hear about about the drugs and midget hookers we had in the truck with us at the time ...

i understand there are a few rough trails out there, just seems like guys vastly overestimate the need for a lifted truck considering their actual usage. a chainsaw, tow strap, and tire chains are way more useful in 99% of the back country scenarios i have seen.
