Z85 vs Z95

[farva1989]

I have a 2019 Yukon slt with the Z85 suspension, the rear air shocks have started to leak (again), they were replaced under warranty at the 2 year mark, and now at the 4 year mark they need to be replaced again and vehicle is off the 3/year warranty and extended warranty wont cover replacement, dealer wants 385 per shock, and I don't want to pay that if I'm replacing them every other year. is there a shock that people recommend to hold up with northern canadian winters, I'd like to keep the air suspension as the ride is fantastic. we don't tow/haul with the yukon as that's what the duramax is for.
the shock I am considering is Arnott MR3626 (RPO code z95) but I'm not sure of the compatibility with the stock RPO code Z85.
thanks.

Buy then at Rock-auto and change them yourself. 15 minutes per side

Z95 is the Magneride suspension which you don't have. Arnott may make aftermarket replacements that are rebuildable. It does not seem normal to me that they are failing so soon, we usually see about 7-8 years out of them before they leak. Maybe the compressor is pumping them up too much?

We had the compressor checked and dealer said everything was within spec,
I’m assuming the northern Canadian winter is the biggest contributing factor in the failure, was hoping to see if anyone up north had experience with an aftermarket shock before buying an oem replacement.

And I didn’t think the z95 shock would work, thank you for confirming my suspicions.

I do remember discussions about this with our Canadian friends on here but don't remember who anymore. If you use the search feature I'm sure you'll come across their posts from this year to about 5-6 years back and can query them for assistance.

Shock failures every few years with this suspension is not normal.
