I believe their similar to the 18 Denali ones which have been fitted on 16-18 base model/ higher up crew cabs through using the upfitter catalog. If anything my guess the At4 would have a pin out for GM lan & running board disable on the fuse block where you could tap into but would not have the same body harness as the Denali where the boards link up on the side of the frame. So essentially you might be able to retrofit them similar to others have done on the forum here. Truck is so new im sure theirs not much out on it, but comes down to how much you want them and if it can be done reasonable. My advice would be to pickup the Denali and work your way down to the look you want. Lot of the Denali parts have high resale!
Selling a set of 16-18 Denali Tri Steps. I know that these can be retrofitted to work on 16-18 trucks per other posts on the forum. Was working on a 2015 retrofit for my truck but didn’t finish and decided to look at purchasing a new vehicle. Overall they are in decent shape, but there is wear and imperfections including a chip in the plastic on the one board. Boards deploy and seem to work fine but being sold AS-IS, I never had the opportunity to get these fully working per the retrofit. Includes both boards and the module needed for the boards to operate retrofit or OEM. They are very heavy and expensive to ship , therefore I’m looking to sell local. Will drive a little ways depending. $500 Local Pickup Located in Washington Twp, Michigan
forgot to update listing, these are sold!
I believe Gen5DIY.com might have one, I know they make the ones for the 16-18 and the 14-15 SLE to SLT conversion.
Still have these will do $600 shipped USA for anyone interested!
15SierraAT replied to 15SierraAT's topic in 2014 - 2018 Chevy Silverado & GMC SierraThe headlights will work on a 14-15 body style with a correct harness no problem. The link on that thread is up above. As for the grill, that will require the entire swap above as the 16-18 grill is larger than the older model.
