I bought the delco locking gas cap. I agree it is a simple cap with a plastic tab that locks it on that isn’t really that great. I can pull it off without unlocking it if I really wanted to. For me, I am more concerned about dust, water, snow getting into the shitty capless system than about the other stuff. There are holes all around the door and rubber that let all of that into the filler area. if someone opens the gas door and sees the locking cap they are more likely to go try another vehicle than deal with the hassle I hope. If you want to save the money the other options of paint can lids, etc will work to keep stuff out of the tank. To me this one just looks a little more robust even it it really isn’t. Hope this review helps others decide either way.

I put load lifter air bags in mine. I lifted the front 1 inch to gain a little clearance before I picked it up from the dealership. I didn’t realize the new trucks had a lot less rake than my 2016 did so 1 inch pretty much leveled it. I don't like squat so I put airbags in. 55psi lifts the truck back up with a load of fire wood in the box and the holiday trailer hooked up. I go the cheap route and just run the two air valves to where the license plate bolts go. It rides slightly rougher with the 5 PSI in the bags at all times but not really that much.

I have the opposite problem on my 2024 2500 AT4. I like 18 inch rims instead of 20’s so that the truck rides better with more sidewall. They told me they could not order the 18’s at the time and I had to get the 20’s option. I made a deal that when the truck came I would get 18 inch wheels and tires swapped. In the past the outside of the tire never changed with factory wheels only the rim size and sidewall did. So I got the truck and new rims and factory sized 18 inch tires. I have come to realize the 20 inch rims had 34 inch tires and the 18 inch factory tire size are only 33 inch. My speedometer is out 5%. So I have to do 105kph to actually be going 100kph. Not the worst thing but here is the catch - I am going to lose my warranty early. About 5000 km early. And that sucks. Two dealerships said even though it is factory size they can not adjust the speedometer. So I am searching for solutions. Yes I could just buy tires that are 34 inch OD but tires are expensive and with. 1mm offset the 33’s just barely do not rub anything. I hate rubbing. 34s will rub.

Has this been updated to include 2024 model years gmc 2500 does anyone know? i just bought one and had this done on my last truck and need it again due to work.

I have Rock Tamers from my previous truck. I did some measurements and used a 1.5 inch hole saw to cut three holes in each flap where the exhaust points at. They don’t heat up at all that I have noticed. i have seen some people also add a piece of mesh over the holes but I didn’t bother.

I told my local dealer the TSB number and then paid them $250 or so to reprogram the truck. I will say one other dealer said they would only do it for emergency vehicles though.

It has been a problem on all GM trucks for a long time. At least since 2003 when I bought my first new GM truck. Economics means they will never make better ones. Warranty to fix a few versus the cost to make millions of hoses better…… Every time it hits -35C here and I start my truck the cooler lines start sweating. Yet I keep buying more trucks ha ha. Necessary for my job. On my 2006 I got the dealer to give me the new warranty hoses and took them to a hydraulic shop to get them make into steel braided lines instead of rubber hoses. Then they installed them. Those ones never leaked again.

I have owned 8 gm trucks. 1990, 2003, 2006, 2008, 2010, 2014, 2016 and now a 2021. I live in Alberta Canada. Every winter as soon as it hits -35C the transmission cooler lines start to weap. Every single truck has had this happen and the new ones are never upgraded. I was told that the few that are covered by warranty are far cheaper than making the hoses on every truck better quality. And in warmer climates this doesn’t happen very often. On my third set for the 2006 ( I kept that truck for ten years) I had a hydraulic shop swap out the rubber part of the lines with steel braided line before installing them. That worked and they never leaked again. Yes I am a sucker for punishment ha ha. But every brand has their issues. They can actually “sweat” for a long time before they start to actually drip just so you know. I have never had one actually blow apart myself.

That is what I did. Drilled two holes in the skid plate above the valence and ziptied it up. Now it is just a tiny little dip right in the middle instead of the large one.

GM sells a locking gas cover for these trucks. It was about $50 in Canada. It is a little cheesy and could be pried off easily but it keeps the dirt out which is all I wanted. Also up here it was shown for 2019’s but not 2021’s. it does fit though.

You can also tie them straight forward and lift the back tires up while someone closes the tailgate. Set the bikes back down on top of the tailgate. Make sure to check them again to make sure they are secured. watch to make sure the front fenders don’t hit the back window though.

Thank you so much for sharing this! I had to pay $255.00 for this here in Canada but now my long distance remote start will keep the truck running up to 45 minutes. Why so long some may ask? Well is is below -30c here this week and 15 minutes doesn’t even get the motor warm let alone the interior. And the factory remote is good for about 200 feet. In hind sight for what I paid for the remote start I could have subscribed to onstar for about 5 years but I hate monthly payments. Will definitely think about it for the next one but for now I am very happy. Now to just find a way to disable stabilicrap……..

They do but that does not help. This is in front of the back tire. Actually right above that plastic. Also it is not a mudflap. It is a wind resister flap. Installed to direct wind around the back tire for better aerodynamics. this is the reason I always get running boards, also because I need them to get in ha ha.

No, i left them at the dealership and got the all weather ones i stead.

I got my AT 4 in February and I ordered those boards. They were backordered and took about three or four weeks to come in.
