Thanks! I bought the Airlift kit with the air compressor awhile ago as my truck was squatting even when just towing my boat so I am excited to try that out, I hopefully will have time to install that in the next couple days here. I also just ordered the updated trans thermostat from GM (#86774933 about $60). I choose that over the pill flip, or thermostat bypass because I read some people that say those can cause some issues in cold weather (I live in MN) and I don't feel like risking it. Thank you for all for the advice, I will be towing on pretty flat terrain so it sounds like I would've probably been fine, but i don't really want to risk overheating and cause any damage to my truck.

Sounds good! thank you!

Ok, Thanks! I really appreciate the help, I will probably end up getting a new thermostat then. Thanks again!

Ok, Thanks! I see you live in Minnesota as well, so I was wondering if there is any issues with a doing a bypass or a thermostat in the winter. I am only asking because the transmission coolers I was looking at previously had a thermal bypass for cold weather climates. I don't fully understand why, but the ones without thermal bypass said "not to be used below 32°F"

Hi, I am new to this form and have been looking at different mods people do to improve towing capabilities, and I am wondering what I need to do for my truck. I have a 2016 GMC sierra 1500 4WD 5.3 v8 all terrain double cab with the 3.42 gears giving me a supposed tow capacity of 9,200lbs. I plan to tow a midsize SUV with a rough curb weight of 5000lbs and use an aluminum trailer with electric trailer brakes weighing roughly 2000lbs, giving me an estimated trailer weight of somewhere between 7000-7500lbs. I have new 33in load range E tires on 18in stock rims, 2in level kit, upgraded slotted/drilled rotors, and a 5000lb rear Air-Lift that i plan to put on as well. I plan to change all my fluids and belts before the trip since I just hit 90k miles. I want to be able to tow a load like this for 6 to 9 hours straight probably once every 3 or 4 months. I also have a larger boat that weighs roughly 3000 pounds that i tow shorter distances regularly. I don't want to spend a ton of money or time, and i don't think i need or can justify a 2500, but what other mods would i need? I was thinking for sure transmission cooler? I don't really want to buy a new radiator but would that be necessary? also would a regear or a tune ever be necessary, or am i fine because i have the 3.42? Thanks!
