Why the Commander is a Great Platform for a Rock Crawler
Before we start wrenching, let’s talk about why the Commander is such a solid choice. It might not have the “RC” badge from the factory like its Maverick cousin, but it has some serious advantages that make it a prime candidate for a crawler build.
One of the key benefits of can am commander rock crawler builds is the platform’s robust, utility-focused chassis. It’s designed to work hard, which translates to durability when you’re putting the frame under stress in a low-speed bind.
Furthermore, its wheelbase and track width provide a stable footprint. It’s not so long that it gets hung up easily, but it’s wide and stable enough to feel planted on off-camber sections. It’s a fantastic middle ground that you can easily build upon.
The Essential Can-Am Commander Rock Crawler Build Guide
Alright, let’s get to the fun part. Building a capable crawler is about making smart, strategic upgrades that work together. This is our ultimate can am commander rock crawler guide, starting with the most impactful changes first. Grab your tools, and let’s get started.
Step 1: Tires & Wheels – The Foundation of Your Build
If you do only one thing, do this. The right tires and wheels are the single biggest performance upgrade you can make. You’re looking for two things: traction and durability.
For tires, choose a dedicated rock-crawling tire with a soft, sticky compound and a tough, 8-ply (or higher) sidewall. Sizes from 30 to 32 inches are a great sweet spot for a Commander, offering a huge boost in ground clearance without over-stressing the drivetrain immediately.
Pair those tires with a set of beadlock wheels. When you air down to single-digit PSI for maximum grip on the rocks, a standard wheel can’t hold the tire bead. A beadlock physically clamps the tire to the wheel, preventing it from popping off at the worst possible moment.
Step 2: Suspension & Lift – For Clearance and Articulation
With bigger tires, you need more room. A quality lift kit is essential for both fitting those tires and, more importantly, gaining precious ground clearance for your belly and differentials.
We recommend a high-clearance suspension kit. Instead of simple bracket lifts, these kits often include new, arched A-arms. These arms give you a true lift in clearance right where you need it—in the middle of your wheelbase. Look for brands that offer heavy-duty ball joints and bushings.
Upgrading your shocks, or at least having them re-valved by a pro, will dramatically improve wheel articulation. This allows each wheel to move independently, keeping all four tires on the ground for maximum traction over uneven obstacles.
Step 3: Armor Up – Protect Your Investment
Rock crawling isn’t a matter of if you’ll hit something, but when. Full underbody protection is non-negotiable. Don’t even think about tackling serious rocks without it.
- Full Skid Plate: Ditch the flimsy stock plastic. A full-belly skid plate made from 3/8″ or 1/2″ UHMW (Ultra-High Molecular Weight) plastic is the way to go. It’s lighter than aluminum and slides over rocks smoothly instead of gouging and grabbing.
- Rock Sliders: These heavy-duty bars mount to your frame along the side of the machine, protecting your vulnerable rocker panels from being crushed by rocks.
- A-Arm & Trailing Arm Guards: These bolt-on plates shield your suspension components from direct, damaging impacts.
Step 4: Drivetrain Upgrades – Handle the Stress
Bigger, heavier tires put a massive strain on your clutch and axles. To avoid being stranded with a shredded belt or snapped axle, you need to beef up the drivetrain.
A clutch kit is your first stop. A kit designed for rock crawling and larger tires will adjust your clutch’s engagement and shifting characteristics. This prevents belt slippage, improves low-speed throttle response, and gives you that smooth, controllable power you need in technical spots. This is one of the most important reliability mods.
For those getting really serious, stronger aftermarket axles from brands like RCV or Turner are a worthy investment. The stock axles are tough, but they have their limits when a big tire gets into a bind.
Common Problems with a Can-Am Commander Rock Crawler (And How to Fix Them)
As you push your machine harder, you’ll find its weak points. Knowing the common problems with can am commander rock crawler builds ahead of time can save you a lot of frustration and money on the trail. Here’s what to watch for.
Snapped Axles
This is the classic crawler problem. It usually happens from “shock loading” the drivetrain—spinning the tires and then having them suddenly hook up on a rock. The weakest link, the axle shaft, gives way.
The Fix: Drive with finesse. Apply smooth, steady throttle. If you feel a bind, back off and try a different line. Upgrading to chromoly axles is the ultimate solution, and it’s always smart to carry a spare front and rear axle in your trail kit.
Overheating and Glazing Belts
If you smell burning rubber or feel the machine start to shudder, your CVT belt is likely slipping and overheating. This is caused by asking too much of the belt, usually by running big tires without a proper clutch setup or trying to crawl in high gear.
The Fix: Always, always use Low gear for technical crawling. It keeps the clutches in their optimal range and multiplies your engine’s torque, putting less strain on the belt. A good clutch kit is also essential preventative medicine here.
Bent or Broken Suspension Parts
A hard drop-off or a sideways slide into a boulder can easily bend a stock tie rod or radius rod. These parts are designed for general use, not extreme impacts.
The Fix: Upgrade to heavy-duty components. Billet aluminum or chromoly steel radius rods, tie rods, and A-arms are significantly stronger than stock. And, of course, driving smart and choosing good lines is your best defense.
Can-Am Commander Rock Crawler Best Practices
Having a capable machine is only half the battle. Knowing how to can am commander rock crawler effectively is a skill. These driving tips will help you conquer more obstacles while keeping your machine in one piece. Follow these can am commander rock crawler best practices for a successful day on the trail.
Air Down for Traction
Lowering your tire pressure to around 6-10 PSI is a game-changer. It allows the tire to deform and wrap around rocks, creating a much larger contact patch and generating incredible grip. You’ll need an onboard air compressor to air back up for the ride home.
Left-Foot Braking
This is an advanced technique but a critical one. Keep your right foot on the gas to maintain forward momentum and keep the drivetrain loaded, while using your left foot to gently apply the brakes. This gives you ultimate control on steep descents or when you need to inch over an obstacle with zero jerkiness.
Pick Your Line and Use a Spotter
Before you approach an obstacle, get out and look. Plan your path. Where will your tires go? What will your skid plate slide on? A good spotter standing outside the vehicle can guide you, helping you see things you can’t from the driver’s seat. Trust them!
Your Can-Am Commander Rock Crawler Care Guide
Rock crawling is tough on equipment. A thorough post-ride inspection is crucial for reliability. This simple can am commander rock crawler care guide will help you catch small issues before they become trail-ending failures.
The Post-Ride Checklist
- Check CV Boots: Look for any rips or tears in the rubber boots around your axles. A torn boot lets dirt in and grease out, destroying the CV joint quickly.
- Inspect Suspension & Steering: Look for anything that’s bent, cracked, or loose. Grab your tie rods and A-arms and check for excessive play.
- Torque Your Wheels: Always use a torque wrench to re-torque your lug nuts after a ride, especially with beadlock wheels.
- Wash It Down: It’s not just for looks. A clean machine makes it easier to spot fluid leaks, cracks, or other damage.
A Note on Sustainable Rock Crawling
Being a responsible off-roader is part of the fun. A key aspect of sustainable can am commander rock crawler culture is protecting the trails we love. Practice Tread Lightly! principles: stay on marked trails, pack out everything you bring in, and avoid spinning your tires unnecessarily to prevent trail erosion.
An eco-friendly can am commander rock crawler is one that doesn’t leak fluids on the ground. Regularly check for oil or coolant drips to ensure you’re leaving nature just as you found it.
Frequently Asked Questions About the Can-Am Commander Rock Crawler
What is the biggest tire I can fit on a stock Can-Am Commander?
On a completely stock machine without a lift, you can typically fit a 28-inch tire without rubbing. To clear 30-inch or larger tires, which are recommended for serious crawling, you will need at least a 2-inch lift kit and possibly forward A-arms.
Is a clutch kit really necessary for rock crawling?
Yes, 100%. If you install larger tires, a clutch kit is not optional—it’s essential for reliability. It re-calibrates your CVT system to handle the extra load, preventing belt destruction and giving you the low-speed control needed for technical terrain.
Can a built Commander keep up with a Maverick X RC on the rocks?
With the right modifications (tires, high-clearance suspension, armor, and clutch), a Can-Am Commander can be an incredibly capable rock crawler that will surprise many people. While the Maverick X RC has advantages like Smart-Lok front differential and higher articulation out of the box, a well-built and well-driven Commander can tackle the vast majority of the same trails.
What’s the single most important upgrade for a rock crawler build?
Tires and beadlock wheels. Nothing else will make a bigger, more immediate impact on your machine’s capability on the rocks. They provide the ground clearance and, most importantly, the traction that everything else builds upon.
Building a can am commander rock crawler is one of the most rewarding projects you can take on. You start with a great machine and methodically transform it into a specialized tool that can take you to incredible places. It’s a journey of wrenching, learning, and driving that connects you deeply with your machine.
