2018 Yukon Denali - Help confirming suspension

[iefstath]

I have a 2018 GMC Yukon Denali 6.2 4x4 which was purchased used in 2019 and now has just under 100K miles on it, my wife's daily driver(daycare/groceries).

I'm fairly sure the shocks/struts are failing as it bounces more than my 10yr old stock Silverado just driving down the road.

My problem is, I can't seem to confirm the proper replacement parts.
- I checked the glovebox and there is no placard with the build info...
- I checked the rear shocks which are labelled UJJ 22312299 18040011, and have an airline attached. I also found the compressor and these appear to be working. The rear bumper was perfectly level while parked in a deep rut.
- I checked the fronts and they are labelled BWI 84176635 18041031 AB44 and AX3 22312296 1804113

I have tried cross-referencing the numbers for the front and I cannot seem to find a match. I can't confirm that they were the originals on the vehicle but it was purchased with 50K miles so I think they probably are.

Does anyone know the correct replacement parts? Or is there another way to confirm the correct suspension? I'm assuming Magneride but don't want to spend that money if I'm wrong.

Thanks in advance.

Magnaride will have a two wire connector on top of the shock, coming out of the body right next to the mount. You should be able to see or feel it without removing a tire.

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

You have no RPO sticker inside your glove box door? How about on the inside edge of the drivers door? Those RPO codes are huge for replacing parts that were installed on your specific truck. If I were to guess, I believe that you have the Magneride (RPO code Z95) active suspension. Along with the primary RPO code Z95, you need to identify the secondary codes for the front left and right struts. Please check and verify that you have (or not) electrical wires going into all 4 shocks.

Also, go to RockAuto.com, one of our favorite replacement parts site, and enter those part numbers and see if you get a match or superseding part number.

There may be a site where you can enter your VIN and get a listing of your RPO codes. @swathdiver

If it is a Denali most likely it has the Magneride shocks with air leveling in the rear. Look for a QR code on the drivers door jamb to scan and look up all of the options.

GMC Denali’s and Chevy Premier’s come with magneride.

1 of your front struts must’ve been replaced. On my 2019 yuk denali xl both are ab44

 

[Tahoe14]

Yes LTZ for years 2015-2016 then they changed the name to Premier starting in 2017-2020.

MR-3626

Suspension Shock Absorber

​

We would recommend Arnotte Industries product - Available through Rock Auto and other vendors. Stick with this type of shock and not a gypsy. Your wife will love you you for it and love the ride.

Magnetic Suspension Shock
MR-3626 is an OES rear magnetic shock for the 2015-2020 GMC SUVs (K2xx) with MagneRide. This universal shock fits both the right and the left side of the GMC SUVs. The magnetically controlled shock from Arnott provides the same highly adaptive ride as the OE. The monotube damper is filled with magnetorheological fluid which is a synthetic hydrocarbon oil that contains easily magnetized iron particles. The two electromagnetic coils inside the damper instantly change the bonds between the magnetized iron particles altering the viscosity and stiffness of the suspension when turned on. Arnotts new universal magnetic ride GM rear shock fits the left or right side and connects to the vehicles ECU with no modifications.

• Direct replacement for GM MagneRide Shock

Arnott recently changed from lifetime warranty on their MagRide struts to just two years.

GM recently changed from one or two year warranty to lifetime on MagRide struts. If possible purchase from R/A to ensure any possible warranty issues in the future will be seamless.

The dealers pricing will be at least double on the same parts. Don’t be made a fool with less costly, “made for MagRide z95” knock offs.
