Every vehicle I have ever purchased has had a towing package. This being my first Chevy (2017 Suburban) I assumed that a towing package on the sticker meant it had a towing package. Apparently, GM does things differently. There is a "Towing Equipment Package" and a "Max Trailering package." The equipment package simply means the vehicle comes with a hitch and light connector and 3.08 gears, period. With this you can tow up to 6300 pounds. The trailering package includes a lower gear ratio (3.42), airbags, heavy duty suspension and a trailer brake controller. With this you can tow up to 8400 pounds. These are the only differences according to GM. We want to get a travel trailer, but the ones we are considering will put us in the 7000-8000 pound range when loaded. If I have the rear end regeared, add air bags and a brake controller can I tow the heavier trailer? Finding a new Suburban with the Max Trailering Package is near impossible, and you can't get it on a Premier, so I would have to give up a lot of the bells and whistles I have on my current LT. I really like my truck and don't want to trade it in even if I could find one with the Max trailer package. What say you?

If I were in your situation, I'd do exactly what you suggested; regear, add a brake controller and maybe airbags if needed.  A trailer that size is going to need a weight distribution hitch anyhow so the air bags may not be needed.  This would be a lot cheaper than the depreciation hit you'd take if you traded in on another Sub so soon.  Do some research and see if there's an existing plug-in under the dash for an aftermarket brake controller.  This would make it much easier to add one.  My 2008 Silverado had a harness tucked under the dash to connect to the controller then a fuse was added to the correct place in the fuse block.  

If your Sub is 4x4, you will need to regear both front and back but that shouldn't run more than $2500 at a reputable shop, maybe cheaper if you shop around.  I had my 2010 Wrangler regeared front and rear for around $1400.

^ This. If any LEO checks you will be illegal according to what the vehicle sticker says. I would go shopping as well and chalk this up to a lesson learned...

Changing all those things doesn't legally raise your capacities.

 

I'd be shopping. 

If those things are the only physical differences between the vehicles then why wouldn't it? Same frame, same engine, same hitch, same running gear (except for gear ratio).

Doesn't change the GVWR and GCWR, especially the GCWR.  You scale it with a re-gear, your combined weight is still 12000lbs.  With max trailer its 14000lbs GCWR.  If the trailer you desire is 7000-8000lbs, you are over weight right off the bat, before even adding people, gear, etc. 

 

If you were to be stopped and they questioned your weight of the vehicle and scaled it, you'd have a problem. 

 

Simply put, the legal, built weights of the vehicle do not change when re-gearing. 

 

A 7000-8000lbs trailer (not including people/gear/etc.) would probably put even a max trailer equipped Suburban right at its limit too for weight.  Run out of remaining payload really quick if you consider 10-15% of the trailer weight should be tongue weight.

I'm not trying to increase the GVWR, just approximate what a similarly equipped Suburban would be able to tow. Went to a Chevy dealer yesterday and talked to a couple of the mechanics. They agree that all the differences between a Suburban with and without the Max Trailer Package can be retrofitted fairly easily, although it will cost a lot more than the $520 the package costs as an option. I'm also not looking to tow at the max. I just want a trailer and gear around 6500-6800 pounds. That's not enough to make trading in on another Suburban worthwhile or cost effective.

I found some good info on my new Suburban in the trailer guide.

 

https://www.chevrolet.com/truck-life/trailering-and-towing-guide

 

The Max Towing with the extra added oil coolers is nice. And long term you will need it, really need to watch trans temps and oil temps without those. Which I dont have but I do have a factory trailer brake controller. Odd they would do that. 

 

Weight distributing hitch would be a must, no surprise there, watch your tongue weight, axle rating, and installed tire rating, as to not exceed you GVWR or the individual ratings of any item.

 

Unsure on tounge weight you can also use a bathroom scale with some wood set up that method is listed in most trailer owners manuals. It's a neat trick I ran across in my research, recently towed a 35' camper was about 9600lb with a different vehicle.

 

Weight Safe makes a neat ball mount with a built in scale for tounge weight. They are very slick products I have a Class V version no scale but very nice on a different truck.

https://www.weigh-safe.com/

 

GCWR (Gross Combined Weight Rating) for mine is listed in that guide at 14k. Would I feel comfortable towing at the upper end, nope.... says max trailer weight of 7,900 again for mine. Would have to weigh the truck with to get a base line. Since 7500 GVWR + 7900 GTW is 15,400 which is over the GCWR. Not sure what the buffer actually is loaded truck and trailer vs unloaded truck and trailer. There is no requirement for "Max Trailering" anything listed, just common sense applies these are not inexpensive vehicles so why beat them into the ground. Air Bags and coolers are the way to go if you can afford them.

 

Alot of the trailers are listed how they calculated the weight, with water, without... with fuel tanks full... ect..... look that up for the trailer you are looking at. Also alot of places will deliver and set up your trailer for you if you dont plan on moving around.

 

Do the homework, work out the math, happy motoring....

 

Here is what I moved last week, not with my Chevy. This would squat both my Chevy's. And be very unsafe.

I'm in the same boat!  I am surprised that a very expensive vehicle should be traded in or ordered just to get the towing capabilities.  After all it is still a Suburban!  I have the premier but without the Max Trailering package.  It would seem logical that I should be able to have the dealer install it for a ridiculous cost, but I have yet to find one that agrees.  Any help would be appreciated.  We have 4 kids and 2 adults wanting to pull a trailer but have yet to pull the plug since we are stuck on the tow vehicle.  Are there any good options since we would need at least a 6000 pound trailer?  We have a 2018 Premier with 4 x 4 and unfortunately 22'in wheels.

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
