Can Am Renegade On 37S – The Ultimate Guide To Going Big And Getting

Ever look at your Can-Am Renegade and think, “It could be bigger”? You see those monster builds online, tearing through mud bogs and crawling over obstacles like they’re pebbles, and a little voice whispers, “I want that.”

That voice is talking about putting your can am renegade on 37s. It’s the pinnacle of trail presence and capability. But it’s also a serious commitment that can turn your prized machine into a garage ornament if done wrong.

We get it. You want the ground clearance, the aggressive look, and the unstoppable performance. We promise this guide will walk you through exactly what it takes—the good, the bad, and the expensive—to build a reliable beast.

Let’s dive into the ultimate can am renegade on 37s guide, covering everything from the essential parts you’ll need to the common problems you’ll face, and how to conquer them like a pro.

Why Put a Can-Am Renegade on 37s? The Ground-Shaking Benefits

Jumping to 37-inch tires isn’t just for looks, though that’s a huge part of it. This upgrade fundamentally changes how your Renegade interacts with the terrain. When done right, the advantages are undeniable.

Here are the core benefits of can am renegade on 37s that draw riders in:

Massive Ground Clearance: This is the big one. 37s lift your differentials, frame, and A-arms higher off the ground, letting you glide over rocks, ruts, and logs that would hang up a stock machine.
Unmatched Traction: A larger tire has a bigger contact patch—more rubber meeting the dirt. This translates to incredible grip in deep mud, loose sand, and on slick rock faces.
Superior Obstacle Approach: Big tires act like a ramp. They have a better “angle of attack,” allowing them to roll up and over obstacles more easily instead of getting stopped dead by them.
Intimidating Trail Presence: Let’s be honest, a Renegade on 37s looks incredible. It’s a statement build that commands respect and turns heads wherever you unload.

The Price of Power: Common Problems with a Can-Am Renegade on 37s

Before you start ordering parts, let’s have a real talk. Stuffing massive, heavy tires under your ATV puts immense stress on components that were never designed for it. Ignoring this is the fastest way to a broken-down rig and an empty wallet.

Here are the most common problems with can am renegade on 37s and how to anticipate them.

Snapping Axles and Breaking Diffs

Your stock axles are the weakest link. The combination of increased leverage from the tall tires and the rotational mass is a recipe for a snapped CV joint or axle shaft. Your differentials will also be under extreme load.

The Fix: Upgraded, heavy-duty axles are not optional. Brands like RCV, Turner, or Gorilla offer chromoly axles designed for this abuse. Consider a differential brace or a full billet differential case for ultimate peace of mind.

Shredding Belts and Burning Clutches

Turning those heavy 37s is like trying to run in steel-toed boots. Your stock clutch simply can’t handle the strain. You’ll experience belt slippage, overheating, and premature failure, leaving you stranded.

The Fix: A comprehensive clutch kit is mandatory. This involves changing your primary and secondary clutch springs and weights to re-gear the CVT system for the larger tires. This is a critical step in our how to can am renegade on 37s process.

Steering and Suspension Failure

The extra weight and leverage will destroy stock ball joints, tie rods, and A-arm bushings. You’ll also find the steering becomes incredibly heavy and unresponsive, making the machine dangerous to control at speed.

The Fix: Upgrade to heavy-duty ball joints and chromoly tie rods. An aftermarket power steering unit (like those from SuperATV) is a game-changer for control. Inspect your A-arm bushings regularly and replace them with high-quality aftermarket versions.

Your Step-by-Step Can-Am Renegade on 37s Guide

Ready to build your monster? This isn’t a weekend project you can rush. Follow these steps methodically, and you’ll build a machine that’s as reliable as it is capable. This is your core can am renegade on 37s guide.

Step 1: The Foundation – Lift and Clearance

You can’t just bolt on 37s. You need to create space. This requires a significant suspension lift.

Bracket Lifts: A 6-8 inch bracket lift is the most common starting point. These kits relocate your shock mounts to raise the frame. Look for high-quality, boxed steel construction.
Portal Gear Lifts (GDP): Portals are the premium solution. These are gearboxes that mount at the wheel hub, providing a direct lift (typically 4-6 inches) and a built-in gear reduction. This takes a massive amount of stress off your axles and drivetrain.
A-Arms and Trailing Arms: You’ll need high-clearance, arched A-arms to clear the tires at full steering lock. For the rear, arched trailing arms provide similar benefits.

Step 2: Drivetrain Fortification

This is where you build reliability. Don’t skip these steps.

Install Heavy-Duty Axles: Remove your stock axles and install a full set of aftermarket chromoly axles. This is a great time to inspect your wheel bearings, too.
Upgrade the Clutch: Purchase a clutch kit specifically designed for your Renegade model and 37-inch tires. Follow the instructions carefully to install the new springs and weights. A new, heavy-duty drive belt is a must.
Brace the Drivetrain: Install a differential brace on the front differential. If your budget allows, upgrading the sprague carrier (in the front diff) to a billet one is a smart move.

Step 3: Choosing Wheels and Tires

The main event! But there’s more to it than just picking the gnarliest tread.

Tires: Choose a tire that matches your primary riding style. Aggressive mud tires (like BKTs or System 3 XTR370s) are heavy but effective. All-terrain styles offer a smoother ride if you do more trail riding.
Wheels: You’ll need aftermarket wheels, typically 18-22 inches in diameter for a 37-inch tire. Pay close attention to the wheel offset. A wider offset (like a 4+3 or 5+2) pushes the wheels out, providing stability and preventing rubbing on suspension components.

Best Practices for Your Big-Tire Build

You’ve built it. Now you have to live with it. A modified machine requires more attention to detail. Following these can am renegade on 37s best practices will keep you on the trail and out of the shop.

Your new setup is heavy. Proper maintenance is key to longevity. This is your essential can am renegade on 37s care guide.

Regular Torque Checks: After every ride, check the torque on your lug nuts, suspension bolts, and portal bolts (if equipped). The increased vibrations can loosen fasteners.
Grease Everything: Your new A-arm bushings, ball joints, and wheel bearings will have grease zerks. Use a quality marine-grade grease and pump them full before every major ride.
Monitor Your Belt: Learn what a healthy CVT belt looks and feels like. Check for glazing, hourglassing, or frayed cords regularly. Always carry a spare belt and the tools to change it on the trail.
Inspect CV Boots: A torn CV boot is a death sentence for an expensive axle. Inspect them for rips or tears after every ride. A small tear can be patched, but if dirt gets in, the joint is likely toast.

A Nod to Nature: Sustainable and Eco-Friendly Can-Am Renegade on 37s Tips

Riding big doesn’t mean you have to leave a big impact on the environment. Being a responsible off-roader is part of the culture, and there are ways to make your build more eco-conscious.

Here are a few sustainable can am renegade on 37s tips to consider:

Tread Lightly: Your massive tires can do a lot of damage to sensitive trails. Avoid spinning your tires excessively, stay on designated routes, and cross streams only at designated crossings.
Proper Fluid Disposal: When changing your engine oil, differential fluid, or coolant, use a drain pan and take the used fluids to a local auto parts store or recycling center. Never dump them on the ground.
Use Biodegradable Cleaners: After a muddy ride, wash your machine at a designated wash bay or at home on a grassy area away from storm drains, using biodegradable, phosphate-free soaps.

Frequently Asked Questions About a Can-Am Renegade on 37s

How much does it cost to put a Can-Am Renegade on 37s?

Be prepared for a significant investment. Between a lift kit, portals, axles, clutch kit, wheels, and tires, you should budget anywhere from $7,000 to $12,000+ for a reliable build. Skimping on parts will cost you more in the long run through breakages.

Do I really need a portal gear lift?

While not strictly necessary, portals are highly recommended. They provide a gear reduction right at the hub, which dramatically reduces stress on your entire drivetrain—from the differentials to the transmission. This is the best way to ensure reliability with such large tires.

Will putting 37s on my Renegade void my warranty?

Almost certainly, yes. Making such drastic modifications to the suspension and drivetrain will give your dealer grounds to deny any warranty claims on related parts. This is a “pay to play” modification, and you become your own warranty station.

What is the best tire pressure to run in 37s?

This depends on the terrain. For general trail riding and rock crawling, a lower pressure of 5-8 PSI will provide a larger contact patch and a smoother ride. For high-speed riding or hard-pack trails, you might increase it to 10-12 PSI to prevent debeading and improve handling.

Building a can am renegade on 37s is one of the most rewarding projects an off-road enthusiast can undertake. It transforms your machine into an absolute monster, capable of conquering terrain you once thought impossible.

But it requires careful planning, a realistic budget, and a commitment to quality parts. Don’t cut corners. Do your research, invest in the right components, and perform diligent maintenance.

Follow this guide, take your time, and you’ll build a beast that not only looks incredible but also gets you deep into the backcountry and, more importantly, gets you home safely. Now get out there and build something awesome!
