If a GM SUV starts feeling rough or unstable on the road, worn shocks could be the cause. One upgrade that makes a real difference is a magnetic shock for GM SUVs. These advanced shocks adjust in real time to road conditions, improving both comfort and control.
The Arnott MR-3626 is a standout option for those needing a reliable rear magnetic suspension replacement. It fits popular models including the Cadillac Escalade, Chevy Tahoe, Suburban, and GMC Yukon built between 2015 and 2020.
Tested over 30 days in a variety of driving conditions—city streets, highways, and rough roads—this replacement delivered noticeable improvement in ride quality.
Here’s how these magnetic shocks help bring back that smooth factory feel.
Unlike regular shocks, magnetic shocks use fluid and metal particles that change instantly when exposed to an electric signal. The system adjusts on the fly depending on how you drive and the road surface. This gives better control, comfort, and handling.
GM SUV shocks with this tech are part of what’s called the Magneride suspension system. The ride stays smooth over rough patches and stiffens up during turns. It’s smart and automatic—no buttons, no guesswork.
The rear magnetic suspension feels especially different on uneven roads. You won’t get that usual bounce or shake.
If your ride feels harsh, your Magneride shocks could be worn out. Most original shocks wear down after 70,000 to 100,000 miles. The Arnott magnetic shock is a solid replacement option.
The Arnott MR-3626 is designed to work exactly like the original factory shock. It plugs in with no mods needed and connects to the existing suspension system. It also fits both left and right rear positions, so you only need to buy one model for either side.
Compatible vehicles include:
I installed both rear shocks over the weekend. You’ll need a torque wrench and a jack that can hold up a full-size SUV. The steps are simple but take some time.
After removing the wheels and disconnecting the old rear shock absorber, the new unit bolts in with factory hardware. I used a basic OBD2 scanner to reset the suspension system. The dashboard warning lights cleared up right away.
If you don’t want to mess with the electronics, a shop can do it for around $200 in labor.
The Arnott MR-3626 costs about $402.36 on Amazon as of June 2025. Other stores like AutoZone and NAPA list it at $561.99. If you're doing a Magneride shock replacement on both sides, Amazon saves you over $300 total.
That’s a big difference for the same part. Arnott shocks also come with a 2-year limited warranty, which adds peace of mind.
I tested these shocks across different terrain. On highways, the SUV felt solid and responsive. Lane changes were tight and stable. On rough back roads, the shocks absorbed bumps without jarring the cabin.
Before the swap, the ride felt floaty and disconnected. After, it felt like the Escalade was back to its original comfort level. One small note—there was a slight stiffness for the first 150 miles. After that, everything settled in nicely.
Always replace both rear shocks together. Doing one side only can mess with the balance of your suspension. Uneven wear leads to strange handling and faster wear on tires and other parts.
Both Arnott units installed perfectly and brought back a smooth, even ride.
If you’re not sure whether your shocks are bad, here are a few things to check:
You can also do a simple push test. If the SUV bounces more than once after pressing down on the rear, the shocks might be worn out.
These shocks cost less than dealer parts but deliver the same performance. They work with your stock suspension system, keep your factory ride feel, and last just as long. Plus, they’re easier to find online than OEM parts.
Here’s what stands out:
If your ride is getting rough and your SUV has Magneride, the Arnott MR-3626 is a solid fix. It handles bumps better, improves control, and restores the smooth ride your vehicle was designed for. It’s also a more affordable option compared to dealer parts.
You can grab one on Amazon for around $402.36. Just make sure to replace both rear shocks at the same time.
Upgrading your rear magnetic suspension with the right parts keeps your GM SUV driving like new. You’ll feel the difference in every mile.
