Help Please- Suspension RPO Code

[tjmclea]

I’ve been searching all over trying to figure out what type of air suspension is in my wife’s 2015 Yukon SLE. It has the trailering package with air shocks for sure in the rear. The rear shocks finally gave way so I am trying to get replacements ordered but I don’t see the standard Z55/Z95/ZW7 RPO code on the service parts identification. Initially I thought since it was a base model SLE it likely just had the premium smooth ride suspension but I’m not seeing that RPO code.

Can anybody identify what this thing has for a rear suspension based on the attached photo?

Well, if I am not mistaken, Z82 is HD Trailering; Z85 is HD Suspension.

Maybe @915_Tahoe can help get you part numbers since the last 6 digits of your VIN are visible in the photo.

This is what I use for that...

Free-Vin-Decoder - Vehicle Identification Number Decoder System

www.free-vin-decoder.com

Put your VIN in, Click on Decode VIN, new Tab will open with your RPO Breakdown. Its usually mostly correct.

are you 100% sure those are air shocks in the rear? do they have a air bladder?
please upload a photo of them.

Yep 100% sure. It has auto level and you can hear the compressor run. The shocks have the air bladder. I’ll snap a photo of the shocks when we get back home from the holiday weekend.

My biggest struggle is understanding what version of air shock I need to purchase to replace the stock shock. Thinking it must use the same shock as the other (non magnaride) air shocks.

well what's weird is the air shocks are z95 and that code is not in your list that was posted, nothing matches your z-codes
regardless you should be able to just order z95 oem or the comparable arnott and they "should" work just fine.
rockauto has them with a lifetime warranty and prices are fair.

Z95 is Magneride.

Z85 is your suspension package. For 2017 it's called Premium Smooth Ride with Air Leveler.

NHT is your max trailering package.

Your rig was made to tow the maximums.

Thanks everyone. I ordered 2 ACDELCO 5401721 shocks and a new Dorman compressor. Fingers crossed the shocks are correct.

I come up with 540-1675/23276087 with Z85 on ACDelco's website

Did Rene give you that number? I would defer to him rather than ACDs or me.

I could not find a shock that showed the Z85 RPO code for 2015 on RockAuto. I jumped up to 2016 and found the 540-1721 listed. Looking at the 540-1721 vs the 540-1675 they look to be almost identical. Compressed length, and fully open length are identical. There are some discrepancies in weight, height, and width, but I am hoping that must be packaging information for the service part in the box. I guess I will see when I get them in a few days if they are going to work for me or not... If they don't I will order up the 540-1675...

Update!! The 540-1721 shocks worked perfectly. I was surprised at how easy it was to swap these out even with 120k miles of Minnesota road salt this rig has seen.

Those salt miles are definitely visible on the old shocks as well. Honestly impressed they lasted as long as they did, as they appear to be the original shocks.


Thanks for all of the responses and input given. It’s refreshing to get some solid support on an online forum.

Hi, thanks for making this forum. I have the same 2015 yukon sle with z85 code and have spent hours looking for the right ones! I almost bought the z95 on rockauto and am glad I didn't. I just wanted to make sure after a year if everything was still working good with these shocks as I am about to order them.

I could use some help.....looking to have a 3.5" lift put on my wife's 2016 Tahoe. All the lifts say they won't work with Autoride or Magneride. All the RPO Codes show that it does not have either.....or am I reading them wrong. I have NHT, Z82 and Z85. And yes there are Air shocks in the rear of the Tahoe. You can hear the compressor running when adults sit in the back seat. Any help would be great.

I don't think the aftermarket has longer air shocks for a lifted suspension. Well, one that would last. If yours were mine I would call Custom Offsets and talk to someone on the cusp of new technology.

Can you not just lengthen the rear ride height sensor rods and have the air leveling give you an extra inch or however much? Asking for a friend.
