My 2019 LT 5.3 with an 8 speed is experiencing the shudder again and the service writer at Covina Hills Chevrolet told me that this time it's because I had it in 4 wheel auto (It's raining) . The advisor told me that the front and rear axle ratios are not the same and this is the cause when you run it in 4 wheel auto. That sounds very odd to me? GM's brochure states tht you can leave it in 4 wheel auto continuously. I had a video of it surging up a hill and they were not interested in watching it whatsoever. Feels like I'm getting scammed or they are trying to wait until it passes 36K and they can charge me for the repair. This is it's second time it's in for the issue. The first time they held it for a few days saying they couldn't get it to act up before they finally said it was fine after they inspected the pan magnets for metal. It ran fine for a couple of days afterwards and then slowly returned to it's herky-jerky self. Now they want me to miss more work to come and ride around with the technician so he can try to feed me more bs I guess. Now Why would I ever consider another GM product? I miss my 07 now.

Stock shocks are way too soft especially with heavy tires on the truck. I have Eibach E60-23-032-01-10 in front set to mid- lift setting with 2 inch leveling kit for about 3-1/4 inch front lift. These are not soft shocks, but handle the larger heavier tires beautifully. I have the Rancho RS999198 adjustables on the rear and I played around with them while unloaded, while towing our jet skis and on Home Depot runs. Set to 1 is too soft especially with heavier 62 pound 10 ply tires so 2 or 3 really the minimum. Set to 8 pr 9 makes them ride like rocks empty but nice with 1000 pounds in the back. 5 in is a nice compromise so I don't have to crawl under and change the settings and is where I now just leave them. I have 2 inch blocks on the rear so I added extensions to cover that.

I tried the flapper clamped open and I feel that the throttle was a little dead off the line like that so I unclamped it and the response returned. I'll wait for a programmer especially one that lets you adjust the rev limiter/ shift points. The truck shifts way too soon. My 07 with a 4.8 and 35 inch tires was shifting north of 6k and it really woke up above 5000 rpm.

From the looks of the instructions and the kit's new harness a simple cut and splice and then the fog lights would receive power from the headlight. Per the instructions you disconnect the factory plug to the headlight and plug it into the new harness which another plug on the new harness then plugs into the head light. Being that everything is LED. I'm thinking that the amp draw may not be an issue.

I purchased mine on Ebay for $189.00 and I just don't feel that comfortable with all that hacking into the electrical systems on the truck. I installed the lights on the truck immediately just for the looks and I'm really considering just connecting them to the headlights. I never shut the fog lights off in my Mustang so I don't imagine I would in my truck either. If you look at the instructions one should be able to modify the new harness to use the power from the right headlight to have them come on with that headlight. My only concern is that the fuse may blow and I should add a relay to prevent that. The hacking into the electrical would be much less involved for those who would say you are still hacking into the electric.

Great post. I'm Considering just the speaker swap for now. Did you listen to the system with just the front speakers swapped? I will eventually get a sub, but I know the stock front speakers need more punch.

Just came across this

I still own a 2000 Mustang GT with a Kenne Bell Twin Screw 2.1 kit and recently replaced the Flowmasters with some quieter mufflers because it was just too loud. They were the first mod I did to the car back in 2000 and now I'm a little older and wanted to hear the radio. I do remember Ford made mufflers for the old FR500 Mustang M-5230-M58 that were quiet until you open it up and a flapper inside the muffler would activate. I would definitely consider something like that for my 19 Silverado. Nice and subdued until you get a little rowdy.

There's that french fry!

I did find that Plasti Dip Selenite Gray is pretty close match, but not perfect a tiny bit darker. https://www.amazon.com/Performix-11357-Selenite-Plasti-Dip/dp/B06XDMWP9F/ref=sr_1_7?keywords=selenite+gray&qid=1577551738&sr=8-7

Added Rear fender Liners since this pic

Thank you!

Domed black with red outline BD Trims (CHEVROLET) and these Ebay Cheapy (Silverado LT) which are not the same size as stock. https://www.ebay.com/itm/1x-GENUINE-SILVERADO-LT-Nameplate-Emblem-Badge-3D-1500-2500HD-OEM-Red-Line-F/163203153443?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 I removed the Silverado badges on the front fenders. The fenders are soft aluminum and you really need to be careful.
