I originally wanted the Denali Ultimate, but it wasn't available to order. Then I Ordered an AT4X, but it was going to take 4-5 months to build and deliver, but no guarantee. So I changed my order to a fully loaded AT4 that was dealer ordered with the engine and color I wanted. So I was able to get it in a month. I was planning on changing the rear bumper on the AT4X to the one from AT4, so I could have exhaust with quad tips. I realized that I didn't really need the AT4X because the main difference is the lockers and suspension, as I wouldn't take it rock crawling or serious off-roading for the departure angles to matter.
Engine - 6.2l (Read somewhere that GM has stopped the production of the 6.2L V8 Engines until next year or possibly longer. Lucky to have mine, just before the announcement)
TIRES - 305/55R22 (35.2inch tall by 12 inch wide)- Nitto Recon Grappler Tires
WHEELS - GMC 22 Inch Aluminum 5-Split-Spoke Wheel - Part# 84799395
EXHAUST - BORLA S-Type with Quad Exhaust tips - Part# 140774BC
My next upgrade is adding the GMC kicker subwoofer to the truck.
Truck exhaust sounds really good! So glad I went with that exhaust. No drone, Quad tips look better than the HDMI exhaust tips.
Wheel and tires are actually smidge taller than 35inch. Toyo Open Country 35X12.5X22 are actually 34.5 inch tall, they have an easier time fitting than these Nitto Recon Grapplers.
The weight of the Stock 275/65R18 tires and wheels was 80lbs.
The weight of the new 305/55R22 tires with 22inch GMC wheels are about 106lbs.
Difference of 27lbs extra per wheel. Which isn't as bad as I thought it would be.
Let me know, if the pictures don't show up.
Anyone using the hypertech inline speedo calibrator? Does it also adjust the fuel mileage along with the speedo?
