Let’s be real for a second. Electric trucks are heavy. Like, really heavy. That Hummer EV? It tips the scales at over 9,000 pounds. The Rivian R1T isn’t exactly a featherweight either. So when you take these beasts off the pavement, the stock suspension—which is tuned for highway comfort and payload—can feel… well, a bit overwhelmed. You feel every rock, every rut, every bump in the trail. And that’s where off-road suspension upgrades come in.
But here’s the thing: upgrading an electric truck’s suspension isn’t the same as lifting a Jeep Wrangler or a Ford F-150. The weight distribution, the battery placement, the regenerative braking—it all changes the game. So let’s break down what actually works, what’s worth your money, and what you should avoid.
Why Stock Suspension Isn’t Enough for Off-Roading
Manufacturers design stock suspension for a compromise. They want decent ride quality on the highway, good handling in the rain, and enough clearance to not scrape speed bumps. Off-road capability? It’s often an afterthought—even on trucks marketed as “adventure-ready.”
For electric trucks, the problem is amplified. The battery pack sits low, giving a lower center of gravity. That’s great for cornering on pavement. But off-road? That low-hanging battery becomes a liability. You need more ground clearance. You need stiffer springs to handle the unsprung weight. And you need dampers that can control the massive momentum of a 7,000+ pound vehicle bouncing over rocks.
Honestly, the stock suspension on most electric trucks is fine for fire roads and light trails. But if you’re tackling Moab or crawling over boulders? You’ll want upgrades. Let’s dive into the options.
Key Upgrades: What to Prioritize
Not all upgrades are created equal. Some give you massive performance gains for the money. Others are just… bling. Here’s what I’d focus on, in order of importance.
1. Lift Kits and Leveling Kits
A lift kit is the most obvious upgrade. It raises the truck’s body or suspension to clear larger tires and improve approach angles. For electric trucks, you need a kit that accounts for the battery weight. Pro tip: Look for kits with progressive-rate springs—they handle the heavy load without making the ride harsh when you’re unloaded.
Some popular options include spacer lifts (cheap, but they don’t improve articulation) and full coilover conversions (expensive, but way better off-road). For the Rivian R1T, companies like Eibach and King Shocks are developing custom setups. For the Ford F-150 Lightning, Rough Country and BDS Suspension have kits that work with the stock air suspension—but you’ll need to reprogram the ride height sensors.
One thing to watch: lifting an electric truck can mess with the aerodynamics. That range hit? It’s real. Expect a 5-15% drop in highway range depending on the lift height and tire size.
2. Heavy-Duty Shocks and Dampers
Stock shocks are tuned for a smooth daily drive. Off-road, they heat up fast and fade. That’s when you get that bouncy, uncontrolled feeling—like a pogo stick on a trampoline. Not fun.
Upgrading to remote-reservoir shocks is a game-changer. They keep the oil cool and provide consistent damping over long, rough trails. Brands like Fox, Bilstein, and Icon Vehicle Dynamics make shocks specifically for heavy vehicles. For electric trucks, look for shocks with adjustable compression and rebound—you can dial them in for rock crawling or high-speed desert running.
Here’s a quick comparison of common shock types:
| Shock Type | Best For | Pros | Cons |
|---|---|---|---|
| Monotube | General off-road | Better heat dissipation, responsive | Stiffer ride on pavement |
| Twin-tube | Light trails, towing | Softer ride, cheaper | Prone to fade under heavy use |
| Remote-reservoir | Extreme off-road | Excellent cooling, adjustable | Expensive, requires maintenance |
| Air shocks | Adjustable ride height | On-the-fly adjustment | Complex, can leak |
3. Upgraded Control Arms and Bushings
When you lift a truck, the suspension geometry changes. Stock control arms might not have enough adjustment to realign the wheels. That leads to uneven tire wear and poor handling. Aftermarket upper control arms (UCAs) with ball joints and polyurethane bushings fix that.
For electric trucks, the extra weight puts more stress on these components. Stock bushings can tear after a few hard off-road trips. Upgrading to delrin or heim joint bushings adds durability—but expect more noise and vibration in the cabin. Trade-offs, you know?
Battery Protection: The Unsung Upgrade
You might not think of skid plates as “suspension upgrades.” But honestly, they’re just as critical. The battery pack on an electric truck is vulnerable. One bad rock strike and you’re looking at a $20,000 repair—or worse, a fire.
Aftermarket skid plates from companies like RCI Offroad or Dirt King bolt directly to the frame. They’re made from aluminum or steel. Aluminum is lighter (good for range), steel is tougher (good for protection). I’d recommend a full set covering the battery, the motor, and the cooling lines.
And here’s a quirky detail: some skid plates come with access panels for the battery drain plugs. That’s a nice touch if you ever need to service the pack.
Real-World Considerations: Weight, Range, and Warranty
Let’s talk about the elephant in the room—or rather, the elephant on the suspension. Electric trucks are heavy. Adding a lift kit, bigger tires, and steel skid plates adds even more weight. That means more strain on the drivetrain, faster tire wear, and a noticeable drop in range.
I’ve seen owners report a 10-20% range reduction after a full off-road build. That’s significant. If you’re planning a long overland trip, you’ll need to account for that—maybe bring a portable charger or plan your route around charging stations.
Also, warranty. Most manufacturers will void your suspension warranty if you install aftermarket parts. Some, like Rivian, are more lenient if you use their approved accessories. Others, like Ford, might give you a hard time. Always check with your dealer before wrenching.
DIY vs. Professional Installation
Can you install a lift kit in your garage? Sure, if you’ve got the tools and experience. But electric trucks have complex wiring, air suspension systems, and battery management sensors. One wrong move and you could trigger a fault code that disables the truck.
My advice? Leave the heavy lifting to pros—especially if your truck has air suspension. The programming alone is a headache. Shops like Expedition One or Offroad Alliance specialize in EV builds. They know the quirks.
The Bottom Line
Off-road suspension upgrades for electric trucks aren’t just about looking cool (though, let’s be honest, a lifted Rivian looks mean). They’re about capability, safety, and protecting your investment. Start with a quality lift kit and shocks, add skid plates, and don’t forget the control arms. Test everything on easy trails first. And always, always watch your range.
The technology is still evolving. In a few years, we’ll probably see factory-built electric trucks with adjustable air suspension that can crawl over boulders like a mountain goat. But for now, the aftermarket is where the magic happens. It’s a bit of a wild west—but that’s what makes it exciting.
So go ahead. Get dirty. Just do it with the right suspension under you.
