I have a 2001 Suburban 2500 2wd. Just wondering if the 2500 Suburbans are also considered HD's

 

Is there any difference in a 2500 truck and a 2500HD truck?

 

Thanks Jim

Hi.

 

Other than cab configuration there is no differance between a 2500 and a 1500HD

 

There are a few differances between the 2500 and the 2500HD

 

The 2500 has a GVW of 8600lbs the 2500HD has a GVW of 9200lbs

The HD sits 2" higher. You can see this by the extra spacer panel between the top of the bumper and the grill.

The 2500HD can be optioned with the D-max so there are some changes in the front end frame.

The biggest diffenance is with the rear end. The 2500 has a semi float design. This causes the axles to carry weight.

The 2500HD has a full float rear end. All the weight is carried on the rear end housing not the axles. This allows more weight to be carried with less wear on the axles.

 

It would be easy to tell if your suburban is an HD. Look at the GVW on the drivers door jamb or remove the rear wheelcover and if there is a bug hub sticking out with 8 bolts holding on the cover it would be a full float rear end.

I thought my 2001 2wd 6.0 gasser suburban had a 14bolt FF, but I sold it a couple of years ago so I am not 100% sure. I do know that it could tow 10,000pds with a WD hitch, which is basically the same as a 2500HD pickup from that timeframe.

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.

      There's absolutely a mountain of profit in catering to the "I do my own research" crowd, people who are certain they know better. And I don't mean there isn't data to support that 0w40 produces less wear product than 0w20 in an engine like the 3.0 Duramax, that only feeds them the assurance they need. Again, my whole thing with oil selection is, sure, 0w40 or 0w30 produces less wear product. Are we talking the difference between the engine lasting only 100k versus 200k? Or are we talking more like, if the engine will already go 350k on a good 0w20 regimen recommended by the OE, is using 0w40 going to get us to 355k, assuming we can even get the rest of the truck to last that long, meanwhile sacrificing the first 5y, 100k in powertrain warranty. The answer isn't easy, there are tradeoffs.   I willfully use 0w20 Dexos D for this reason, knowing that a 0w40 will produce slightly less wear. I don't believe the delta in wear product is meaningful over the lifetime of the engine, and I place much more importance on driving style and overall feeding and care of the engine as a whole. It's the mentality that someone can abstain from alcohol their whole life which is an amazing boost to health by itself, theoretically. But if they're sedentary, that lifestyle choice will most likely kill them young despite their other, concerted efforts. Maybe someone doesn't drink AND they are the perfect picture of health and activity AND they use 0w40 AND they treat their engine perfectly. If living until 130 years is the goal, sure, do that. But it's going to be a really old truck falling apart around a good engine for that last 30 years, without a doubt.   I watched Demonworks' other video on the 100k+ 3.0 Duramax that had dealer 0w20 changes on what appears to be OLM-prescribed intervals (8-10k).   The QR codes are still present and readable on the main bearings. That's how little wear it has.   That's not proof that anyone else should stick to 0w20, but it's confirmation, for me, that 0w20 is perfectly acceptable to use in these engines.
