2026/2027 Suburban — confirming AS3 bench delete with standard MagRide/Adaptive

[3CarSeatDad]

I'm trying to confirm whether a 2026 Suburban 4WD can be factory-ordered with the second-row powerfold bench seat option (in place of standard captain's chairs) while keeping the standard Magnetic Ride Control. Multiple dealers have said the option isn't visible on their tools. Has anyone here either successfully ordered this config, or found an authoritative RPO code that confirms availability? Bonus points if you can post a build sheet or window sticker showing this combo.

Here's the 2026 order guide - Vehicle Order Guide

 

RPO code "AS3"?  Not seeing it.  What is it supposed to be?  I see AS3 used a long time ago as some sort of seat option, but its not applicable to the current Suburban. 

 

I see RPO code "AZ3" which is 1st row 40/20/40 split bench.  That is only on LS trim, which LS can't option any of the trick suspension.  

 

2nd row bench power fold RPO code is "ATT".  So your dealer should be able to sort their locator to find matching builds by searching the combo of ATT and Z95 combined to find a 2nd row power fold with MagRide.  

 

You can do the 2nd row power bench AND have MagRide, or Mag with Air on Z71, RST and High Country.  

 

Here's a Z71 with 2nd row power bench and the Z71 Off Road Package which adds the Adaptive Air and MagRide - 2026 Suburban | Details | Vehicle Locator

 

Here's an RST with 2nd row power bench and the RST Capability Package, and RST Capability adds the Adaptive Air with Magride - 2026 Suburban | Details | Vehicle Locator

 

I can't find a High Country, but you can do it on there.  Requires the 6.2, and the Sun and Tow pack which allows you to then option the 2nd row power fold.  Black interior only.  High Country comes standard with MagRide and you can order the air if you get the High Country Deluxe, but Deluxe will take you to captain 2nd row.  

 

 

You can do it at GMC on the AT4 and the regular Denali (not Ultimate) as well.

Thank you for sharing! I reached out to the dealer of the cars you highlighted. They said the same thing.  You cannot have 8 seater bench and MagRide/Adaptive suspension both.
