Not entirely sure if this belongs here but here goes.

 

So when i bought my 2011 1500 new from a small dealer who had good reviews (who went under about a year after i got my truck) I thought i was getting a truck with the 3.42 gearing and HD cooling package as that was what was on the sale sticker and the paperwork, The weight according to the manual fit what i planned to tow and I was assured by the dealer thats what i was getting, it was also on the paperwork amd it does have the trailering package so i bought the truck.

 

Well i took it in to be serviced at a large chevy dealer in minot and i got a rather nasty shock, When we were talking i told him about my plans to buy and tow a nice camper that is about 7000 pounds, well dealer pipes up and says that would be a bad idea as i only have a 3.08 gear ratio and no hd cooling....

 

So im wondering if upgrading to a 3.73 gear ratio with bigger tires and putting a heavy duty transaxle cooler on will bump me upto the weight listed in my manual as the only diffrence i can see is the cooler and 3.42 gearing, or if i am missing a few things?

 

I have been quoted at $2500 installed if i dont need a new computer to accept the new gearing is this about inline with cost?

 

Sorry for long winded post and poor grammer typeing something this detailed on a phone is not a fun experince.

I have a towing pkg on my truck, but it is not the max towing pkg. I have 3.73 rear end, but since I don't have much of anything else, the only benefit I get is more torque on take off, not hauling more weight, and only 18mpg hwy. My trucks towing weight limit is 7,700 lbs. The tounge weight should be no more than 10 - 15% or 600lbs for a 1500 truck. I have no heavy duty springs so I would need to do some serious upgrades if I would want to tow or haul heavy weight. I also have a transmission cooler,(I think they all do) but I didn't see any mention of it being heavy duty. I also have the 4 speed auto sold in 09.

The 3.73 is for torque/power, all the other stuff is for being strong enough to handle the weight and keep it running cool.

 

I would suggest looking at the owners manual for your specific year and see what options were available and what would be needed to tow the weight you want. They keep changing things each year so yours will be different than other years.

Fair enough, as of right now i have heavy duty springs and shocks all after market the stock ones didnt seem to like offroad in north dakota much, i also have the 6 speed transmission in mine, i know the transmission cooler is stock so when i get my gearing changed to 3.73 i was going to have a high end one swapped in and a special cooler for my pumpkins i was told about.

 

Seems the only things i still needed to reach the manual listed 10000 pounds were the cooling package and gearing, but i will be honest i know squat about doing upgrades and just need to know what im missing more then anything, i know getting a bigger truck is the best option but due to id theft my credit is shot so im stuck with what i have.

 

This is all new to me and i want to make sure i dont screw my baby up in the process.

You can check your RPO sticker to make sure you really know what you have RPO for 3.08 is GU4 and the Heavy Duty cooling package is K5L.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
