Always heard good things about Arnott stuff I wouldn’t hesitate to run it.

If these are $275 each, why do people go crazy with regular shocks, and playing with resistors, and trying to undo $10zillion dollars worth of GM engineering ??

Because for essentially the same price for all 4 corners you can get traditional dampeners and simulators and not have to deal with the magnetic dampening failing.

Traditional dampeners fail too. Even my LS truck, I had to replace all 4 corners. Granted, I had a bigger selection to choose from, but only once in the lifetime of a truck are you replacing shocks & struts.

Yes of course they fail. OEM equipment especially there are vehicles with leaking shocks right off the showroom floor.

But you can run Bilstein or other quality components for a fraction of the price.

These magnaride shocks are failing at like 50k or less, so if you plan to keep it a while you could be replacing them multiple times over the ownership of the vehicle.

That hasn’t been my experience. The fronts on my ‘07 have 210k on them and my original rears on my ‘12 lasted for 117k. Still has the original fronts. That’s about as long as conventional shocks and struts will last, too. I find the factory autoride system great for handling and towing, and with rock auto selling the OEM parts for less than $250/corner, I see no reason to go aftermarket for my purposes. The only reason I’d go aftermarket would be for a significant lift.

On the 2015 and up Magnaride the strut is $350-$450 each and you have to reuse your old springs , mine failed after 40K miles and rode like crap , replaced with KYB struts and springs already mounted and added some resistors , the truck has never run better and for only $140 each , and from what I read on these forums the original mag ride struts seem to leak after 40-50K miles ,

I guess it depends on how and where you drive. Mine have 137k miles on them but need changing in the spring.

so it's worth keeping a z55 or z95 suspension vs bilstein on 4 corners? I want to do all 4 corners but if the ride quality is better with the oem then I'll keep it

It's worth keeping your Z55, it helps with handeling plus I notice on windy days, the Z55 soaks up wind gusts. Plus it rides much nicer than standard suspension.

+1 to keeping the OEM system (at least for the GMT900 generation - I don't have any experience with the newer trucks). It's well engineered, durable, and I find it easy to work on on the rare occasions I've needed to, such as changing out the rear shocks and compressor.

Ok, so I'm wanting to replace the OE front struts on my 2012 Denali. I don't have the Z95 rpo code, only the Z55.

The front struts have a connector plugged into the top and I've looked at the Arnott SK2954 and it says it includes a sensor to eliminate dash panel error messages.

Is this the model I need? I'm confused, sone descriptions say it's a conversion shock and that it's a "passive" replacement. It also lists having the 6DA/7DA spring codes, but mine are the 6F1/7F1

Passive means a conventional strut not electronically controlled so for anyone with auto ride it is a conversion to a passive strut. It appears that this is the right pn but I haven’t used them and can’t verify the spring type. Someone that has will chime in.

the only replacement I have found for the front z55 suspension is Monroe 40049 which is in that $300-$350 range. if I remember correctly the AC delco equivalent is about the same price.

this is what is on my truck now

When I looked up for my 14 denali awd.. I got the monroe 40048 w Z55 Susp
and the ACdelco # was 580-434
Hope this helps.. This would be the correct OE replacement... And retain
the factory Z55 active handling. Which is what I'll do when it's time.
I did the rear shocks last summer with the correct ACdelco air ride shocks
