First post here, and have to say a happy owner of the 2022 elevation with baby diesel. Great truck and luv the drivability of it. 
 

I bought it to tow my boat which is approx 9k lbs with trailer. The truck tows it perfectly fine, but the rear is sagging a bit. I am measuring 2.25 inch drop. I was wondering if anyone has done research to potentially swap out the rear springs on the standard elevation to a max tow leaf spring set? My understanding those are designed to carry more weight thus increasing the tow capacity. There are other things like different gears etc that at in the tow package that I am not going to tackle yet. But eventually will regear to 3.73 once the warranty period is up. Please post the part numbers for the rear springs if you have done similar swap. Thanks!

You can't increase towing capacity. It is what it is. Get some airbags.

Not looking to increase towing capacity, but get rid of the sag. Don’t want to get involved with airbags. Adding a leaf is not an option, don’t want to raise the rear. Want to see if anyone did a swap using a max tow spring set.

What's the tongue weight of the trailer with the boat? 

 

Max tow springs and shocks won't gain you much of anything.  Max Trailer is more the gearing and higher capacity radiator.

 

It seems you've got a weight issue.  Too much tongue possibly if you are dropping that much.

9K 2500 IMO

3500 minimum.. I have been towing various toys for over 20 years. Having towed 9k 1200 miles with 1500 diesel, I would say that it is capable to pull a whole lot more. The most stable 1/2 ton platform I ever towed with. Having said that, If I upgrade my boat in the future, 2500 would be my choice.

Thought about any of the Timken or SIS load bearing bump stops?

I have the same truck, in a '21 Denali CC. It does not take much for these to sag. I only tow 5500 lbs with 600 lbs of Tongue weight. Its down more than any normal truck. This is a common complaint. The truck does have sway control and the special shocks as its designed this way. Tows great. But I have to adjust my hitch to level the trailer so I dont load up the front two tires as they will run hotter than the rears. Noticed that in our fantastic towing app and TPMS sensors in the trailer tires. Its understandable to want the max leaf springs. Will be a better fix than airbags.

I ll do a little more research on part numbers to see if they are different. Moved the boat back a few inches, that helped with the sag and tows little better. Feels like the actuator is no longer getting stuck.

I did the same with the car, and height of hitch. Once it sags, if trailer in pitched forward or back its loading the front or rear trailer tires. In the trailer app I noticed the front tires were a higher psi and were hotter. Once leveled all was perfect. Something I wouldnt have thought about years ago, and can see how that would be prone to a blowout possibly. Airbags arent an option for the Denali as it has the autoride shocks and a some sensor back there that is in the way. If I go heavier I will need leaf springs. The ride is great though when not loaded.

Correct.  The GVWR of a max trailer vs a non max is only 200-300lbs higher.  Its still a 3 spring pack, just a slightly stiffer spring rate.  That's it.  Airbags, add-a-leaf, Timbrens, Sumo Springs or Roadmasters would be the route to take.

Which brings me back to too much tongue.  9000lbs trailer might be within the capacity of the tow rating, but tongue should be 10% of the trailer weight, 15% max.  That's 900lbs-1350lbs tops.  That eats HARD into a 1/2 ton truck payload, even on a max trailer.  

 

The limit here with your boat is the truck.  Smaller boat would be better or larger truck.  

 

2500HD would be the ideal truck.

I dont agree that a larger truck is needed. This truck is perfectly capable towing a boat this big. Now if it was a camper, perhaps that would have been a different story. The boat I have is probably most I would tow with the 1/2 ton. 

 

How can I find out the part numbers on the max trailering package rear springs? I have read on numerous sites that they are stiffer. Curious if the parts are in fact different from what I have. Googling GM part numbers catalog is not coming up with anything productive.

Curious on two things here quick.  Up above I asked if you measured the tongue weight of the boat trailer.  Have you?  What's the # if so?

 

Second.  Can you post a picture of the door trailer tag on your truck inside the driver's door jamb?  Should have the max trailer weights, GVWR, GCWR and payload.

About the springs..... On another thread here, someone posted a picture of the rear springs on a 2023 1500 (without Max trailering).  The springs are a single piece composite unit! I have not seen what the springs are for 2023 with max trailering.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Yes.   Yes.   We might be intermingling ideas with the term 'severity', in one of my past vehicles it could pull up DTC via the vehicles own user interface, at any given time when one would do this there would be an assortment of codes that were 'trivial' including 'communication' issues. This would generate a bunch of, potentially false alerts or some many that they would get ignored. Which you mentioned earlier.    You also mention several things that might be redundant with the vehicles own systems or indicators: The truck has an oil pressure gauge, monitoring it via this other system wouldn't be a priority except in comparison to other values or if there is an actual oil pressure problem.   Same thing for miss-fires or other problems, the MIL already signals the operator to an issue...   ...to the point about what one wants to see first, if there is a miss fire detected, I want to see miss fire counts or fuel trims first, if I have an oil pressure problem I want to see the oil pressure first. So, perhaps the 'systems' that are showing abnormalities are what gets displayed first.   I think your device is what connects at the OBD port, ease of use for the consumer, it could still have a 'pass-through' port for a second scanner, computer, etc.   Yes.   Based on my comment above, if an error appears, the report would be more specific to the system having an error.

      I like the idea.  I thought about putting a deposit a few years ago when they first dropped.  I still want to drive one and have inquired about doing this with them, like a ride and drive event they said they are coming but it hasnt happened even with them built in Indiana.

      Transmission Woes :-(

      By asilverblazer · Posted

      That's a tough spot to be in, I personally would question spending 1/2 the book value on a repair vs. selling it as-is.    Presuming you own it out right, sell it for 10k and have a down payment for a replacement truck, or spend 10k on the one you already have...   I still think there is a cheaper transmission out there via recyclers, aftermarket or rebuild. (Cheaper than 5k for the unit)

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Sadly, there's a drought of good 92-95 4.3 cars at junkyards in the area otherwise I would have gone fishing for parts. Not that they don't come up, there's just nothing good in the yards right now.   I tore into the intake yesterday evening, easier than I thought, and I might have this problem licked for cheap. Two of the intake studs came up with the bolt on removal, no big deal but that's why it looks funny with studs only on one side.   There's pooled gas on both sides of the plenum. Highlights boxed in green. Picture-right side has an obviously split pressure line from rubbing on the #5 injector nylon line. #5's line is worn in that spot but not all the way through. Passenger side intake (picture left), not sure, but I think the pressure regulator is hosed. Rebuilt spiders don't come with the pressure and return hoses so I'll need to replace those no matter what. A pressure regulator is $30 so I'll try that and if I end up having to swap the whole spider, it was $30. I'll be grinning ear to ear if that's all I need.   Parts arrive Tuesday.   Sure enough the shop was here before. That's a new gasket. Vacuum lines and wiring are a tangled mess, I sorted that out last night as well. Spent about an hour just picking up general slack and shoddy reassembly around the engine bay. Cheek-pokered the battery tray, got it all cleaned up. Sometimes things just need a little elbow grease and a few minutes of time to be right again.
