2500 Vs 3500 Srw

I have read a recent thread where it was mentioned that adding an extra spring to the back essentially made the 2500, a 3500 SRW, so is this the only difference between the 2 models?

 

I pulled my 2009 Silverado brochure and the max hitch trailering actually decreases with the 3500 by 400lbs (grant it that was comparing a 6.0 CC 4x4 6'6" box with 4.11 gears to a 6.0 CC 4x4 8' box so I realize the added 1.5' adds weight) so there must not be many (if any) if any differences such as larger brakes.

 

I will be towing a 10,000lb travel trailer, so I won't be near max, but was just wondering.

Adding the extra spring certainly will help with towing. However, it won't legally change the GVWR of your truck. ;)

You'll notice a big difference towing with an added spring and payloads. The spring I had added supports 2000lbs and before adding the spring, when I use to put the trailer on the truck would go down some, but thats a thing of the past now. Well worth the investment imo. I'm also going to keep an eye on if my tires wear less now over time. Pulling a trailer every week up inclines has worn tires down faster for me. Even though I will be pulling/carrying same weight with added spring, was curious if less weight would be placed on tires because of added spring.

 

The only thing different on 2500 vs 3500 is 3500 comes with extra spring (5 springs and a helper) vs 2500 which has (4 springs and a helper). And I am not sure if a 3500 uses a heavier torsion bar in front vs a 2500. Everything else is the same.

I believe the wheels and tires are different also. I think the 3500 SRW comes with 265's and wider wheels.

 

Either one will do fine pulling a travel trailer. I would only expect minimal mileage though. :)

My 2500 is only rated to tow 9,800 but then again I have the 3.73, not the 4.10

 

I understand the difference between 3.73 and 4.10 gears, but it's amazing that it would make a 2,500lb difference.

 

What milage are you getting with the 3.73 gears? Towing was the main reason for buying a 2500HD with 4.10 gears, so when I am getting 2-2.5mpg less unloaded in town than the 08' 1500 I had, I wasn't disappointed, just wondering how much difference the gears make.

I get from 11-13 around town and 15-15.5 pure highway.

Are you sure about that? Only 9,800? The 1500's are rated at 10,500 last I checked, your truck has to be at least rated at 12,500 seeing it's a 2500.

Yeah 12K & change for the deisel but only 9.8K for my gasser. I even checked the 2008 brochure I still have from the dealer with all the specs. Only the 1500 with the Max trailering package gets up to 10.5K. Same 6.0 engine but I think has a few more Horses.

See the link below to a 2009 brochure. 9.8k for a 6.0 gasser with 3.73.

That's a pretty odd thing for GM to do, de-rate towing capacity by almost 3k for like what, 10% difference in gear ratio? That's an almost 30% drop in capacity...Somebody got their inverse proportions all screwed up.

 

Well let's just say I've gone way beyond what they rate my particular setup for...Definitely gonna be regearing to 4.10s or 4.56.

Hey Hen... I looked under at the rear in my '06 1 ton at work. 8.1 with Allison....The rear is visibly stouter and larger than the rear in my '07 6.0 gas 3/4 ton. there is an extra spring like you said. but I think the rear is bigger.

The same weight will be placed on the tires (actually slightly more weight, because that added spring leaf weighs a few pounds :lol:)

Mike, the 8.1L and D-max have the 11.5 14bolt FF and the 6.0L 2500HD has the 10.5 14bolt FF, and the v-max has the 9.5 14bolt as is not a full floater.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.

      AFM Disabler Question

      Melling I believe is/was the OEM on the lifters who explored this problem some years ago. The white paper they generated on the topic indicated two items of note when I read it. 1.) They only fail on the switch. Prevent the switch, prevent the failure. 2.) The majority fail due to deposits messing up the timing of that switch. Anyway that's what I got from it.    Mine have always been active, 195K+ now, and my oil maintenance is surgically clean.    Of course this assumes good parts. That is no heat treat issue or machining flaws. I get comfortable that these issues are in the rearview mirror by about 30K. IMHO naturally.
