The MagneRide Trap: Why Standard Leveling Kits Ruin the Sierra Denali
Share
You just bought a beautiful 2014–2018 GMC Sierra 1500 Denali. It has the massive 6.2L V8, incredible leather, and rides like an absolute dream. But you hate the factory nose-dive, so you go online and order a highly-rated set of premium leveling struts to fix the stance and clear larger tires.
You spend the entire Saturday ripping the factory suspension out and bolting the new struts in. You lower the truck, start the engine, and your dashboard instantly lights up like a Christmas tree with aggressive "Service Suspension System" warnings. Worse, when you hit the highway, the truck bounces violently, completely ruining the legendary Denali ride quality.
You just fell directly into the MagneRide Trap.
Unlike standard SLE or SLT trims, the Sierra Denali is equipped with Magnetic Ride Control (MagneRide). The factory shocks are filled with a specialized magnetic fluid and hard-wired to an advanced computer system that reads the road 1,000 times a second. If you remove these electronic shocks and bolt in standard mechanical struts, the computer freaks out, and your suspension fails completely.
You don't have to live with the factory rake, but you absolutely have to respect the electronics.
In this guide, we explain exactly how to safely lift your Denali using MagneRide-specific spacer kits and sensor relocation brackets. We'll show you why Bilstein 5100s are the ultimate upgrade for non-MagneRide trucks, why cheap plastic spacers crack under pressure, and how to safely build your stance.

Frequently Asked Questions (Leveling Kits)
Do I absolutely need an alignment after installing a leveling kit?
Yes, it is 100% mandatory.
When you raise the front suspension of your GMC Sierra, you completely alter the toe and camber geometry of the front wheels. If you bolt on a leveling kit and skip the alignment to save $100, your tires will literally drag sideways down the highway, completely balding a brand-new set of expensive mud tires in less than 2,000 miles.
Will a 2-inch leveling kit allow me to run 35-inch tires?
No, they will violently crush your fenders.
A standard 2-inch leveling kit on the K2XX Sierra platform is engineered to comfortably clear 33-inch tires (like a 285/70R17 or 275/60R20) on a factory-offset wheel. If you try to stuff massive 35-inch tires under a simple leveling kit, the rubber will violently smash into your metal cab corners and sway bar the second you turn the steering wheel.
Can I install leveling struts in my driveway?
Yes, but you need a heavy-duty coil spring compressor.
If you buy a bare adjustable strut like the Bilstein 5100, you must remove your factory shock assembly, compress the highly lethal factory coil spring with a specialized tool (available to rent at local auto parts stores), unbolt the top hat, and transfer the spring over to the new shock. If you are uncomfortable doing this, buy a "Loaded Strut" assembly or take it to a professional shop.
Delete the rake. Clear the tires.
Ditch the factory nose-dive and the dangerous plastic pucks. Upgrade your stance with heavy-duty forged spacers, zinc-plated struts, or massive aluminum coil-overs. Shop our verified collection of premium 2014–2018 GMC Sierra 1500 Leveling Kits.
