Ever feel like your Can-Am Defender is beating you up on the trail? You hit a bump, and it feels like the whole machine bottoms out with a jarring thud. Or maybe you’ve loaded it up with gear for a work week, and the rear end sags, making the steering feel light and floaty. You’re not alone. Many owners think that’s just how a UTV is supposed to ride, but we’re here to tell you it doesn’t have to be that way.
At FatBoysOffroad, we promise to give you the real-world, no-nonsense advice to get the most out of your machine. We’re going to pull back the curtain on one of the simplest yet most impactful upgrades you can perform: adjusting shocks on can am defender. It’s a game-changer for comfort, capability, and confidence.
In this guide, we’ll walk you through why this matters, what tools you’ll need, and the exact step-by-step process to dial in your suspension. You’ll learn how to transform your ride from harsh and unpredictable to smooth and stable, no matter the terrain or task.
Why Bother Adjusting Your Defender’s Shocks? The Real-World Benefits
Before we grab the tools, let’s talk about the “why.” Adjusting your shocks isn’t just for pro racers. It’s a fundamental tuning option that Can-Am built right into your machine. Understanding the benefits of adjusting shocks on can am defender will motivate you to get this done right.
Enhanced Ride Comfort
This is the big one. By adjusting the shock’s preload, you can fine-tune how the suspension reacts to bumps. A softer setting can soak up small trail chatter for a plusher ride, while a stiffer setting can prevent harsh bottoming out on big hits. It’s about finding that perfect balance for your typical use.
Improved Handling and Stability
A properly set up suspension keeps your tires planted on the ground. When your Defender feels tippy in corners or squirrely at speed, a shock adjustment can often bring back that feeling of control. It helps manage body roll and keeps the machine level and predictable.
Increased Load Capacity and Ground Clearance
Do you use your Defender for work? Hauling firewood, tools, or feed can make the rear end sag. By increasing the preload on the rear shocks, you can compensate for the extra weight, restoring your ground clearance and preventing the suspension from constantly bottoming out. This is a must-know for anyone who puts their UTV to work.
Reduced Wear and Tear
When your suspension is constantly bottoming out, you’re putting immense stress on shocks, bushings, ball joints, and even the frame. By setting the preload correctly, you allow the suspension to operate within its intended range, which can extend the life of these critical components.
Understanding Your Can-Am Defender’s Stock Shocks
Most Can-Am Defender models come equipped with 5-way adjustable, cam-style preload shocks. This might sound technical, but the concept is incredibly simple. You’re not changing the shock’s internal valving; you’re changing the initial tension on the spring.
What is Preload? A Simple Explanation
Think of preload as setting the ride height of your machine. The shock spring holds up the weight of the Defender. By increasing preload, you are compressing the spring slightly before any load is put on it. This makes the spring stiffer initially.
- Less Preload (Softer): The spring is less compressed at rest. This allows the suspension to sag more, providing a softer, more compliant ride over small bumps. This is great for comfort when riding empty.
- More Preload (Stiffer): The spring is more compressed at rest. This raises the ride height and makes it harder for the suspension to compress. This is ideal for carrying heavy loads, aggressive driving, or preventing bottoming out.
The adjustment is made via a stepped “cam” or a threaded collar at the bottom of the spring. Your job is to rotate this cam to one of its positions (typically 1 through 5) to set the tension.
Tools and Safety First: What You’ll Need
Before you start cranking on anything, let’s get our gear in order. Having the right tools makes the job easy and safe. This isn’t a complex task, but skipping safety steps is a recipe for disaster.
Essential Tools List
- A Solid Floor Jack: Don’t rely on the flimsy scissor jack from a car. A good hydraulic floor jack is a must-have for any DIY mechanic.
- Jack Stands: NEVER work under a vehicle supported only by a jack. You need at least two sturdy jack stands rated for the weight of your Defender.
- Spanner Wrench: This is the most important tool. Your Defender should have come with a spanner wrench in its factory toolkit. If you’ve lost it, you can buy a replacement from your dealer or an aftermarket one online.
- Wheel Chocks: To prevent the machine from rolling.
- Wire Brush & Penetrating Oil (like PB Blaster or WD-40): Your shock threads will be covered in mud and grime. Cleaning them is non-negotiable.
- Tape Measure: To measure ride height and ensure your adjustments are even.
- Gloves and Eye Protection: Standard safety gear for any shop job.
Safety Precautions
Your safety is more important than any adjustment. Read this twice.
- Work on a flat, level surface. A sloped driveway is a no-go.
- Engage the parking brake and chock the wheels that will remain on the ground.
- Use proper lifting points. Consult your owner’s manual for the recommended frame locations to place your jack and jack stands.
- Confirm the vehicle is stable on the jack stands before you put any part of your body underneath it. Give it a good shake. If it wobbles, re-position everything.
The Step-by-Step Adjusting Shocks on Can Am Defender Guide
Alright, you’ve got your tools, you understand the theory, and you’re ready to go. Here is how to adjusting shocks on can am defender, broken down into simple, manageable steps.
Park on Level Ground & Secure the Vehicle
Ensure you’re on a hard, level surface like a concrete garage floor. Put the Defender in Park and engage the parking brake. Chock the wheels on the opposite end of the vehicle from where you plan to lift first.
Lift the Vehicle Safely
To make adjustments, you need to take the weight off the springs. Lift either the front or rear of the Defender until the tires are a few inches off the ground. Place your jack stands securely under the frame and slowly lower the jack until the machine’s weight is resting firmly on the stands.
Clean the Shock Threads and Cam
This is a crucial step. Use your wire brush to scrub all the mud, dirt, and corrosion off the shock body and the adjustment cam. Spray it liberally with penetrating oil and let it sit for a few minutes. This will make turning the cam infinitely easier.
Locate the Preload Adjustment Cam
Look at the base of the shock spring. You’ll see a ring with several “steps” or notches in it. This is the cam. There will be an indicator mark on the shock body to show you which setting it’s currently on (from 1 to 5).
Use the Spanner Wrench to Make Adjustments
Fit the hook of your spanner wrench into one of the notches on the cam. Apply steady, firm pressure to rotate it. You may need to put some muscle into it, especially if it hasn’t been moved in a while. Pro-tip: Pushing or pulling toward the vehicle often gives you better leverage.
Adjusting for a Softer vs. Stiffer Ride
- To soften the ride (less preload), turn the cam to a lower number (e.g., from 3 down to 2). This lowers the cam, reducing spring tension.
- To stiffen the ride (more preload), turn the cam to a higher number (e.g., from 3 up to 4). This raises the cam, increasing spring tension.
Match Adjustments Side-to-Side
This is critical for predictable handling. Whatever setting you choose for the left shock, you MUST set the right shock on the same axle to the exact same number. Mismatched settings will make your Defender handle poorly.
Lower the Vehicle & Test Ride
Once you’ve set both shocks, carefully lift the machine off the jack stands, remove them, and lower it back to the ground. Before you go for a ride, bounce on the suspension a few times to let it settle. Now, take it for a spin on a familiar trail to feel the difference. Don’t be afraid to go back and try a different setting if it’s not quite right.
Best Practices and Pro Tips for Shock Adjustment
Following the steps will get the job done, but applying these adjusting shocks on can am defender tips will make you a pro. This is what separates a good setup from a great one.
Start with Small Adjustments
Don’t go from setting 1 all the way to 5. Make one-step changes at a time. The difference between each setting is noticeable. Go up or down one click, test it, and then decide if you need more.
Keep a Log of Your Settings
This is one of our favorite adjusting shocks on can am defender best practices. Use a small notebook or a note on your phone. Write down the date, the front and rear shock settings, the load you were carrying, and how it felt. This helps you quickly return to your “empty trail riding” setup after a weekend of “hauling firewood.”
Adjusting for Specific Conditions
- General Trail Riding (Empty): Start with the factory setting (usually 2 or 3). If it feels harsh, try going down to 1 or 2.
- Heavy Loads or Hauling: Crank the rear shocks up to 4 or 5 to prevent sagging and maintain stability. You can often leave the front shocks on a softer setting.
- Plowing Snow: A heavy plow will make your front end dive. Increase the front preload to 4 or 5 to counteract the weight and keep your blade height consistent.
- Aggressive Driving: If you like to ride fast, a stiffer setting all around (3 or 4) can reduce body roll and prevent bottoming out on g-outs and jumps.
When to Consider an Upgrade
Stock shocks are a compromise. If you consistently ride with heavy loads or are an aggressive driver who is always on the highest preload setting and still bottoming out, it might be time for an upgrade. Aftermarket heavy-duty springs or fully adjustable shocks (with compression and rebound damping) are the next logical step.
Troubleshooting Common Problems with Adjusting Shocks on Can Am Defender
Even a simple job can have its hiccups. Here’s how to handle some common problems with adjusting shocks on can am defender.
Seized or Stuck Adjustment Collars
This is the #1 issue. The cause is dirt and corrosion. The solution is more cleaning and more penetrating oil. Let it soak, tap the collar gently with a rubber mallet to break it loose, and try again. In extreme cases, a little bit of heat from a propane torch on the collar (be careful of seals and plastic parts!) can help it expand and break free.
Uneven Ride Height
If your Defender leans to one side after adjustment, you’ve messed up. Double-check that the preload settings are identical from left to right on the same axle. If they are, you may have a worn-out spring on one side, which needs replacement.
Still Bottoming Out After Adjustment
If you’ve maxed out the preload (setting 5) and you’re still hitting the bump stops hard, you’re asking too much of the stock springs. You are a prime candidate for heavy-duty aftermarket springs, which are designed for exactly this scenario.
A Note on Sustainable and Eco-Friendly Shock Care
Part of being a responsible owner is thinking about our impact. A proper adjusting shocks on can am defender care guide includes sustainable practices. When cleaning your shocks, opt for a biodegradable degreaser to minimize chemical runoff. By tuning your suspension correctly, you extend the life of your shocks and springs, meaning fewer parts end up in the landfill. This is a core part of sustainable adjusting shocks on can am defender maintenance—making your parts last as long as they were designed to.
Frequently Asked Questions About Adjusting Shocks on Can-Am Defender
How often should I check my shock adjustments?
It’s a good practice to check them as part of your pre-ride inspection, especially if you frequently change your load. At a minimum, check and clean them a few times per season to ensure the adjusters don’t seize up.
Can I adjust the shocks without lifting the Defender?
While technically possible on some models if you can get the wrench in there, it’s extremely difficult and not recommended. Taking the weight off the spring makes the adjustment cam 100 times easier to turn and is the proper way to do the job.
What’s the difference between preload, compression, and rebound?
Preload sets your ride height and initial spring stiffness. Compression damping controls how fast the shock compresses (like when hitting a bump). Rebound damping controls how fast it extends back out. Stock Defender shocks only have preload adjustment; more advanced aftermarket shocks allow you to tune compression and rebound.
Will adjusting my shocks void my warranty?
No. This is a standard user adjustment feature designed by Can-Am for you to use. It is outlined in your owner’s manual and will not affect your vehicle’s warranty in any way.
Tuning your suspension is one of the most rewarding DIY jobs you can do. It costs nothing but a little bit of your time and completely transforms how your Can-Am Defender feels and performs. So get out in the garage, get those shocks dialed in, and get ready for a better ride on your next adventure.
