Hey folks, I'm going to order my truck this week and I'm in doubt between the 2500 and the 3500 SRW. I would like to know what the differences are between them. I've looked in several places and haven't found it. I'm not a towing guy but I like to be prepared if I need to. I will use it for trips with the family and daily use in the city. From what I saw, the price difference is very small between them. I'm ordering the Denali Ultimate.

Yeah I like ordering a vehicle so nobody test drives it and abuses the brand new engine. My truck had 2 miles on it when I took delivery.

There are other recent threads on this, but here’s a summary as I remember it. 
 

The rear spring pack on the 3500 has one additional leaf. The 3500 rear spring system also has an overload spring where the 2500 does not. The 3500 GVWR and payload rating are higher (obviously). My 3500 cclb gas has a payload rating of 4,055 lbs. Typical 2500s have 3000 to 3400 I think - others may jump in with actual numbers. 
 

Because of the suspension difference, the 3500 has a bit stiffer ride at a given weight versus a 2500. The rear seat especially feels the stiffer ride when the truck is empty. With my 1800 lb slide-in camper in the bed the truck rides nicely.  The 20 inch wheels on a Denali will make the ride even stiffer versus 18s. 
 

The rear tire pressure monitoring system alarm point is about 10 psi higher on the 3500, limiting how low you can set the rear tires for empty running to 63 psi without getting a warning. I wish I could go to about 55 when empty (I have 18 inch wheels).  On the 2500 you can. 
 

If you have a diesel, I believe the 3500 has a slightly larger rear differential ring and pinion gear set 12” versus 11.5” on everything else. 
 

On the 3500 you can only have the huge moose antler towing mirrors. They seriously obscure the view to the right to see pedestrians at intersections. Make sure you drive trucks with both the standard and towing mirrors. This might be a big factor for you. On the 2500 the towing mirrors are optional. 
 

The 3500 has the much cooler “3500” emblem on the doors. However if you get the Denali there is no emblem so you constantly have to tell people it’s a 3500 if you want to be cool.

This topic has come up plenty lately. Mtu alum and Newdude both already posted the true difference and it’s not additional leaves. Both trucks have the same five leaf pack with one being an overload.

Here is MTU's comment:

 

While the 2500 is a two stage and 3500 is a three stage, the second stage (bottom leaf) engages quicker on a 3500 vs a 2500.  The main four leaf pack is similar between both, the rest is different. -Credit to MTU Alum

So they both have a four leaf pack and both have overload spring but slight differences. I know my 2500 has five total leaves. I mean there has to be some  difference to account for the 500+ pound payload increase the 3500 sees.

About the mirrors, they are the same on 2024 Denali HD models. The emblem, both have just a little plate on front bumper. They are pretty looking good truck. About the suspension and rear axle, I dont know NOTHING. But thanks for helping.

I may be using the wrong terminology, but by “overloads” I meant the separate leaf spring above the main spring pack that engages its own set of bumpers on brackets bolted the frame. There was quite a bit of discussion about the 2500 not having this spring and not having the frame mounted bump stops for it. A person was wanting to add that spring and the bumpers to his 2500.

From my research and from what newdude said, the 5 leaf spring packs are identical in the 2500 and 3500 trucks.  The only difference is the 3500's get the 2 extra springs above the spring pack and the overload bumpers for them.  Those 2 extra springs are what increases the payload over the 2500's.  I could be wrong as I've been before, but my research says I'm right.

There are multiple part numbers of rear spring packs. Remember that thread?

You are correct.  Most of the differences that I've seen include the overload springs that are attached to the "basic" 2500 springs.  Then we get into the long bed springs vs. the short bed springs.  They also have different Part numbers for reasons unknown to me.  But getting back to the basic 2500 spring pack, that's what I'm referring to.

I have a 2500 and if I was to do it again I would seriously look @ 3500 long bed ....Ride is similar have heard  though a hair stiffer and you get extra capacity.....TPMS sensor is a bummer for 3500s as I run my 2500 pretty low for DD.....it helps more than anything to soften sharp hits.....still for HD truck it rides pretty friggen nice......remember my buddy buying a new Ford F350 some years ago and that thing rode like a brick....

 

Have 23 high country 2500 and am @ 3495lbs for payload on a gas motor.....diesels will be less of course...as well as higher trims

My 3500 gasser LT that's pretty much loaded has a payload of 4,040 lbs. I tend to agree with everyone here on the differences(frame, rear end, overload springs, no torque management in 1st gear). For the extra $1100, i'd go with the 3500 again all day long. I aired down the rear tires to 65ish and the ride is much better than at 80. No regrets at all on this truck.

I wish I had bought a 3500 to begin with.  But they were non existent when I was looking last year.  As a hint, drop the rear tires to 55 and the fronts to 65.  Makes them ride like a caddy...lol....

Dropping the rears to 62 triggers the TPMS low pressure warning on a 3500. 

And there again the differences between the 2 models.  I'm glad you posted this for the 3500 owners!

      Replacing 2.7L on 2021 Silverado with 2023 2.7L

      OCI, not when but why?

      By KARNUT · Posted

      But Grumpy I did show several subdivisions that had homes starting in the 170K range. If you bought a Townhouse or Condo you could go cheaper. Same with a car 3000 dollars in the 70s translates to around 20K today. There are several models at that price. You actually get more for the money. In the 70s I drove a 3000$ car bought a 28K home and made 4.50 per hour. Thank goodness for overtime. Today I could buy a 170K house drive a 20K car and make 25 dollars an hour operating the same machine today. The difference the house, car, machine would be better and have AC. And I wouldn’t be taxed on overtime. And statistically your wife works too. Easing the burden. I thought we agreed to disagree. I brought receipts earlier, showing examples. I think you’re more stubborn than me. I was done with this debate.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.
