Arnott MR4262 for replacing front Magneride Z95 suspension info

[mrkev]

Just put in the Arnott MR4262 suspension for my fronts.
I'll post some info, for those deciding to use Arnott, ACdelco, or others.
I went with the MR4262 because I thought it was an Eibach shock and spring with magneride fluid inside. Well, im not sure if it's eibach, I dont see "Eibach" anywhere on the spring or shock. I was debating to get just the shock and re-use the spring to save about 200$ total for the pair. I am glad i did NOT. After installing the Arnotts, my front end was lifted about 2 inches. I think the old suspension has sagged overtime, and since im not the oG owner, I have no idea of how high the front was brand new.

The newly installed Arnot was squeeky for the frist few speedbumps, but now and quiet and smooth. Also did the trim height adjustment on the Autel, since the ride in the front is 2 inches higher now (although it did not throw any codes). Let's see if this settles over time.

My recommendation is to use Arnott with the spring installed, since your old springs have probably already sagged. With the spring already installed, installation is very easy. AC delco does not sell pre-loaded Magneride shocks/springs.
Dont buy AC delco from Ebay, they are cheaper, but they are 99% fakes. (I wouldn't buy from amazon either for the same reason)
NOTE: there are 4 versions of Arnotts offered.
1. Magneride shock only
2. Magneride shock only (but passive, so it bypasses the magneride)
3. Magneride shock and spring* this is what I got because I wanted to keep the magneride functionality.
4. Magneride shock and spring (but passive)

of course you can bypass it altogether and get FOX or Billies. lots of info out there or Mag Del. If the Arnotts fail, I'll give Fox a try.

Hope this can help others.

Thank you! Here's the pic of the truck 1000 miles after the Arnott front Shock and Springs.

update after a 700mile road trip. I would give these Arnott's a 9/10. I have 2 issues with this systems.
The first... the fronts sometimes make a squeaking noise when going over speed bumps too fast.
The Second... When going over a small hump at high speeds, it feels like the whole car got some air. What I mean is that the suspension seems to fully extend for a second before compressing. I dont remember my old shocks doing this (even though they were leaking and sagged about 2 inches.)
overall, the road trip was smooth. I did drive a 2024 Wagoneer during this trip and the Wagoneer is waaaay more quieter and smoother than my 2016 Yukon. I did notice that it had considerable more body roll than my Yukon. My yukon was planted during turns. I am happy with that.

further update with a few hundred more miles and different types of roads. I think the fact the suspension was lifted 2 inches means the suspension is stiffer.

In my other cars (stock suspension) going over a hump at a high speed, the car suspension would extend then land softly.

With my yukonXL and Artnott Active spring/shocks, going over same humps at high speeds (40-55 mps) it feels like the car gets some air. The suspension seems like it gets extended to the max before it compresses, you can definelty feel the jolt. It feels like the stiffer sport suspensions of my coilovers on other cars.

being that i've only had experience with my Yukon with stock blown/sagging shocks and springs, I dont have much to compare it to. I did rent a Wagoneer during the same 700 road trip, and wow, that suspension was smooth. more body roll, but very smooth over bumps and humps.

I guess that's the tradeoff with Magneride and having good handling.

Anyone else with Stock Magneride chime in? How does your car do when flying over humps at about 40-50mph?

thanks
