Rear wheel well liner
jhplak325 replied to Trailblaster's topic in 2020-2024 Silverado HD & Sierra HD Mods
You will have to get them from GM, trucks built between 3/21/22 to 4/4/22 the rear wheel liners wasn't included at the factory. That has since been changed. -
2500/3500 Denali visual differences?
jhplak325 replied to gemarsh's topic in 2020-2024 Silverado HD & Sierra HD
OP is looking at Denali's and on Denali's and AT4's just say DenaliHD or AT4HD on the doors, no place on the truck does it say 2500 or 3500, has been like this since 2011 when the Denali was introduced to the HD line. -
I had the same problem back in the middle of April after the dealer installed the illuminated sills, after some communication with GM about the issue, they released new installation instruction end of April and where you tap into for power is a different location. Dealer changed the location and have not had a problem since. illuminated sills 4-28-21.pdf

Dual batteries on a gas engine is not part of the plow prep package. -
Military, Educator and First Responder discounts are now only $500. Prior to this month they where the same as Supplier.

Thanks and you have a sweet setup also! Really impressed with the 10 speed and how smooth it shifts. Definitely like the turn signal cameras, but my biggest thing is getting used to them.

AT4 and 5th Wheel towing
jhplak325 replied to xETERNALx's topic in 2020-2024 Silverado HD & Sierra HD
No difference in height between an AT4 and Denali on the HD’s. -
I just got this a month ago and pulled the camper for the first time this past weekend, unloaded and loaded it rides a lot better than the 2015 GMC Sierra 2500 Denali HD I had. Really impressed with this truck. 2021 GMC Sierra 3500HD on stock tires.
