I sent my 2019 Silverado 2500HD to the dealer last Monday for a ton of error messages (lane assist, trailer assist, airbag, seat belt; basically all the safety related systems were showing off line) showing on the dash. (speedo, tack and all gauges not functioning). They just called me 3 hours ago and said they found standing water in the passenger kick panel area and in a wiring connector. They couldn't locate the source for the water leak. They opened up the area and dried out the wiring connector and kick panel area. Tested the truck and reported the truck passed the "water test". I pick up later this evening. I will look around the running board, lower section of the door, window seal, door seal and windshield and wiper cowl area, headliner and shark-fin antenna and sunroof for signs of water. Op. Hope you get yours repaired.

Recently I added 285/65R18 BFG KO2's to my 2014 Silverado. I installed Bilstein 5100's up front on the highest setting. I did the teardown of the stock coilovers but I had a local shop swap the shocks out in the coilovers for $75.00. Installation in the truck was super easy. Have absolutely no rubbing on the felt or sway bar. I removed the front airdam thing just cause it sucks. Speaking of sucking; I still have the craptastic RanchoMcNuts on the rear. I need to get to get to that soon. I purchased 3" lift blocks along with the longer Bilstein rear shocks but haven't installed them yet. Been too busy. You can't go wrong with 285/65R18 BFG's and Bilsteins.

Nice write up. I have 3" blocks in the rear with Bilstein 5100. Interested if this will fit?

Wow - what? I too just installed my Bilstein 5100's and everything worked perfectly. Do you have a photo showing the interference fit with the spring hat?

Ha! I would love to see those numbers on a consistent basis, but I know that's impossible with the 5.3 6 speed. Have fun with the power adder.

This past Saturday I wanted to see what the highest MPG I could get on a 240 mile trip. Most of the journey was rolling 2 lane hwy in Missouri. I have a 2014 Crew cab Z71 4x4 5.3 with 6 speed. I was averaging 50 - 60 MPH, the best was 29 MPG. Unless I change my driving habits greatly, this mileage is not sustainable as I was coasting & feathering a lot toward the last 75 miles of the trip to push the numbers higher. My normal Hwy MPG has been in the 22-24 range with MPH of 65-70. I think I can learn how to increase long term hwy mileage to 25 MPG. It made a boring trip more enjoyable.
