I’m looking at 2017-19 Crew cab short bed duramax trucks what is the difference between the 3/4 ton and 1 ton srw? From what I’ve read the 1 tons have overload springs on the rear axle and 18” wheels is that the only difference between the two and the increase in payload and gvwr?

Front torsion has a different part number. I’m pretty sure 1 ton came in 20” wheels as well in srw.

Badging is different as well.

I believe the 1 ton also has a larger rear axle, but I could be wrong.

i think 2500 gas trucks get a smaller rear, 2500 diesels and all 3500s get the bigger rear.

What is your intended use case?  

 

If its a diesel engine to tow, go with a 1 ton for the maximum possible amount of payload, especially with a big trailer or 5th wheel.  2500hd is hampered quite a bit with the diesel with payloads as low as 2100-2200lbs on a loaded up crew cab.  1 ton you will see payloads 2900-3500lbs crew cab diesel depending on trim.  

 

If you aren't towing big but still looking diesel, a 2500 will do it for you. 

 

One VERY important thing to look for on a 1 ton is the GVWR.  They did have the option to de-rate the GVWR on them to 10,000lbs.  It cuts the max payload a LOT, back down to 2500hd levels and was an option for "legal" reasons for businesses and DOT rules.

Correct.  10.5" on gas 2500hd, all diesel and gas 1 ton use the 11.5" axle.

1 tons got only 18" wheels on SRW.  The wheel/tire package offered the most payload capacity for the ratings of the 1 tons.  2500hd got 17, 18 and 20 inch options.

Not sure what all that means.

But the 2017 LTZ 3500 SRW had the same chrome star wheels as my 2017 LT C/S when I bought it in 2016. It was really nice brownish gray color.

Maybe they were Dealer installed?

Yea, someone must have put them on it because they wanted 20"s.  The tires are rated for less weight that GM used.  17 inch and 20 inch were a 121 load index tire, the 18 inch was a 124 load index.  The load carrying ability of the 18 inch tire is hundreds of pounds higher per tire, hence why 1 tons only were built with 18 inch wheels.  On the new 2020+up, its 18 inch or 20 inch as the tires they picked for both are 125 and 126 load index.

I appreciate all the responses I would use it for towing camper. Bumper pull atm but maybe 5th wheel in future. I’m just wondering if a 2500 with the overload springs on it are specd to a 3500 as far as gvwr and payload amounts about the same or close. The 2500 hd market is a lot more available than 3500. I understand the dot would probably not believe if that was the case and would question it all the way.

DOT, from what I understand, only cares about RAWR and tire rating. The tax man might care about GVWR because you didn’t pay enough tax for your loading. You’ll also read about how if you are over GVWR that your insurance won’t cover you in an accident and all that jazz. This is another internet lore and I’ve not seen a real example where his has happened (it may exist and hopefully someone with a link to a case will post it here). Last I checked, it’s illegal to speed, make an improper left turn, drink and drive, but coverage isn’t automatically denied. I suppose if you were way over loaded, to the point of gross negligence, you might be in trouble. Also, if you are at fault, you are at fault; doesn’t matter if you are over weight unless you were so overweight that it was a contributing factor in the accident then maybe there’s additional punishment or liability? And anyone can sue anyone, but contingency fee lawyers much rather go after insurance policies because they actually pay. Good luck getting a $500k+ judgement paid by Joe Schmo; garnish his $50k a year salary and renew the judgement every 7 years.  That’s how those big accident attorneys get rich. (Insert rolling eyes emoji to indicate sarcasm; lots of folks can’t detect sarcasm just by reading text). 
 

if you’re going fifth wheel, the 3500 setup is preferable. They are harder to find. The 2500’s are plenty capable. Just go to a campground and see what gets towed with a 2500 class truck of any brand.

As a fellow RV'er, don't look at the campground. I can assure you every single toy hauler hooked to a diesel 2500 is over payload.

 

If a 5er is in your future, get the 3500 or a new body 2500 with higher payload. My 2019 Gasser does great, but my "Half-Ton" 5th wheel is light on the pin. My payload is 2570#, which isn't horrible, but it's not the 3k+ of the newer trucks. Better to get a bigger truck now so you're good on whatever you want later.

Legally per the weight tags on the door jamb, the payload, RGAWR and GVWR don't change if you had a 2500hd and added the 3500hd helper springs. 

 

In practically sense, yes it would equal it to a 3500hd from the factory.

      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.

      OCI, not when but why?

      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.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
