If you're looking to fit bigger tires without a massive lift kit, installing forward a arms can am defender owners often recommend is usually the smartest first move you can make. It's one of those modifications that actually serves a dual purpose—it makes your rig look significantly meaner while giving you the functional clearance you need to navigate nasty terrain. Most of us who use a Defender for more than just hauling hay know that the factory wheel wells are a bit tight. Once you start eyeing those 30-inch or 32-inch tires, you quickly realize that the stock geometry just isn't going to cut it.
The main reason people go this route is to solve the dreaded "tire rub." When you're turning the wheel or hitting a bump, the back of the front tire tends to grab the plastic fender well. By moving the hub forward—usually by about 1.5 to 2 inches—you create a much larger pocket for that tire to live in. It's a simple mechanical solution to a common clearance headache, and honestly, it's a lot better than just cranking up your pre-load and ruining your ride quality.
Why the Forward Offset Matters
When you install forward a arms on your Defender, you're essentially stretching the wheelbase. That 1.5-inch or 2-inch jump doesn't sound like a lot on paper, but in the world of suspension geometry, it's a game-changer. It pushes the front wheels further toward the front bumper, which clears up space near the firewall. This is exactly where most of the rubbing happens on a stock Can-Am.
Beyond just fitting bigger rubber, that extra wheelbase adds a tiny bit of stability. If you're climbing a steep ledge or working on a side-hill, having a slightly longer footprint helps keep the machine feeling planted. It's not going to turn your utility UTV into a long-travel sand rail, but you'll definitely notice a more composed feeling when things get vertical. Plus, the approach angle gets a nice boost. Since the tires are further forward, they're often the first thing to contact an obstacle rather than your front bumper or skid plate.
The High Clearance Advantage
Most aftermarket forward a arms aren't just moved forward; they're also "high clearance." If you look at your stock arms, they're pretty much straight across. This means if you're driving over a rock or a downed log, that straight arm is the lowest point and is likely to get hung up or dented.
High-clearance arms feature a distinct "bend" or "arch" in the tubing. This design tucks the arm up higher, away from the ground, providing several inches of additional clearance without even changing your ride height. It's like getting the benefits of a lift kit without the added stress on your CV axles. When you combine the forward offset with the arched design, your Can-Am Defender becomes a much more capable woods machine. You can pick lines through rock gardens that would have had you high-centered on the factory parts.
Durability and Material Choices
Let's be real: the stock Can-Am arms are okay for light farm work, but they can be a bit flimsy if you're heavy-handed on the trails. Most forward a arms you'll find on the market are built from heavy-duty tubing, often DOM steel or even Chromoly. This makes them significantly more resistant to bending when you inevitably clip a stump or drop the front end into a deep rut.
Usually, these arms come with a thick powder-coated finish. This isn't just about looks—though a pop of color under the wheel well does look sharp. The coating protects the metal from the constant barrage of mud, salt, and rocks. If you're a rider who spends a lot of time in the swamp, you know how fast rust can move. Investing in a set of beefy, well-coated arms means you won't be worrying about structural integrity five years down the road.
Dealing with Ball Joints and Bushings
One thing that catches people off guard is what to do with the ball joints and bushings. Some kits come "naked," meaning you have to press out your old ball joints from the stock arms and move them over. If you've ever tried to do this without a heavy-duty press, you know it's a total pain in the neck.
I almost always suggest buying a set of heavy-duty ball joints and a fresh set of bushings when you buy your forward a arms. Why put old, worn-out parts into brand-new, high-performance arms? Many manufacturers offer the option to have the ball joints pre-installed. Take that option. It'll save you hours of frustration in the garage and ensure that your front end is tight and responsive from the first ride. If you stick with the stock plastic bushings, you'll probably be replacing them sooner than you'd like anyway, so look into HDPE or Delrin bushings for a much longer lifespan.
The Installation Process
Putting on forward a arms is a job most DIYers can handle in an afternoon, provided you have a decent jack and a few basic tools. You'll need to support the frame so the suspension can droop fully. Once the wheels are off, it's mostly a matter of disconnecting the tie rods, shocks, and the sway bar (if yours is equipped with one).
The trickiest part is usually managing the axles. You don't want them to pull out of the differential or over-extend the CV boots while you're swapping the arms. Using a few bungee cords to hold the spindles and axles out of the way can save you a lot of grief. Once the new arms are bolted up, make sure you torque everything to spec. Since these are moving parts that hold your wheels on, "good and tight" isn't always good enough.
Steering and Alignment
After you've got everything bolted back together, don't just go rip it down the trail immediately. Moving the hubs forward changes your toe-in and toe-out settings. If you don't realign the front end, your steering will feel twitchy, and you'll eat through your expensive new tires in no time.
Most people find that they need to adjust their tie rods out a bit to compensate for the new geometry. A simple string alignment in the driveway is usually enough to get you back in the ballpark. You're looking for a slight bit of toe-out or a neutral stance, depending on how you like the steering to feel. Also, keep an eye on your steering stops. Some forward a arm kits include steering stops to prevent the CV joints from binding at full lock, which is a small but vital detail if you want your axles to survive.
Is It Worth It?
If you're asking yourself whether the investment is worth it, think about how you use your Defender. If it never leaves the gravel driveway, you probably don't need them. But if you're using your machine for hunting, serious trail riding, or working in deep mud, forward a arms are one of the best bangs for your buck.
They allow for larger, more aggressive tires, they improve your ground clearance, and they strengthen the front end of the machine. It's a foundational mod—the kind of thing you build the rest of the machine around. Plus, there's no denying that a Defender with a wider, forward-leaning stance just looks right. It takes it from looking like a golf cart on steroids to looking like a legitimate off-road powerhouse.
Just remember to check your clearances once everything is installed. Even with the forward offset, every tire brand measures a little differently. A "30-inch" tire might actually be 31 inches, and you'll want to make sure you aren't hitting the bumper or the inner plastics at full compression. Once you've got it dialed in, you'll wonder why the factory didn't just build them this way to begin with.
