Can-Am Commander Suspension Parts: A Complete Guide to Upgrades and Maintenance

The suspension system of your Can-Am Commander is the backbone of off-road performance and ride comfort. Whether you’re tackling rocky trails, dune riding, or utility work, understanding the key suspension parts—and knowing which upgrades deliver real improvements—helps you get the most from your machine. This guide covers the main components, common upgrades, and practical maintenance advice.

Key Components of the Can-Am Commander Suspension

The Commander’s suspension consists of several interconnected parts that work together to absorb impacts, maintain tire contact, and provide stability. Here’s what you need to know about each.

Shocks (Dampers)

Shocks control the motion of the suspension by dampening spring oscillations. The Commander comes with either gas-charged or high-pressure gas shocks depending on the model. Aftermarket shocks—like Fox, Elka, or Walker Evans—offer adjustable compression, rebound, and sometimes ride height. Choosing the right shock depends on your terrain and riding style. For example, Fox Podium RC2 shocks are popular for desert racing due to their high-speed compression adjustment, while Elka Stage 5 shocks suit technical trail riding with fine-tuning capabilities.

Springs

Coil springs support the vehicle’s weight and absorb initial impacts. Stock springs are typically progressive rate, designed for general use. Aftermarket springs can be dual-rate or triple-rate for improved bottoming resistance and a plusher ride over rough terrain. Spring rates (pounds per inch) should match your Commander’s weight and typical load—heavier loads require stiffer springs. For example, a Commander XT with a full skid plate and gear may benefit from a 150-200 lb/in spring.

Control Arms (A-Arms)

Control arms connect the chassis to the wheel hubs and control wheel travel and geometry. Stock Commander arms provide moderate travel. Aftermarket arms—such as long-travel kits from MotoAlliance or SuperATV—increase wheel travel by 2–4 inches, improving articulation and stability. They also allow for better shock angles and stronger ball joints. Be aware: longer arms often require shock relocations or bump stop adjustments.

Sway Bars (Anti-Roll Bars)

Sway bars reduce body roll during cornering. The Commander has a front sway bar; some models also have a rear. Unhooking or replacing the sway bar with a quick-disconnect system can improve articulation for rock crawling, but increases body lean on high-speed turns. For mixed riding, an adjustable sway bar offers the best compromise.

Bushings and Ball Joints

These wear items affect suspension precision. Stock rubber bushings flex and degrade over time. Upgrading to polyurethane bushings reduces deflection and sharpens handling. Ball joints (upper and lower) should be inspected regularly; aftermarket versions with grease fittings last longer and allow easier maintenance.

Common Upgrades: What to Prioritize

Not every upgrade is right for every rider. Focus on the changes that match how you use your Commander.

For Trail Riding

• Shocks: Adjustable shocks (like Elka Stage 1) with remote reservoirs prevent shock fade on long trails.
• Arms: Standard-length aftermarket arms with stronger ball joints provide durability without breaking the bank.
• Springs: Upgrade to dual-rate springs if you carry cargo or tow.

For Rock Crawling

• Sway Bar: Quick-disconnect or remove front sway bar for maximum articulation.
• Long-Travel Arms: 2-inch longer arms allow deeper articulation and better obstacle climbing.
• Shocks: Longer shocks with bypass adjusters help control the added travel.

For Dune and Desert Riding

• Shocks: High-speed compression adjustability (e.g., Fox Podium RC2) to handle whoops and jumps.
• Springs: Stiff springs to prevent bottoming out at high speed.
• Bushings: Polyurethane to reduce feedback and maintain alignment.

Maintenance Tips for Your Commander Suspension

Regular checks extend the life of your suspension parts and keep them performing at their peak.

• Inspect bushings and ball joints every 50 hours for play or cracking. Replace immediately if loose.
• Check shock seals and oil annually. Leaking shocks need rebuilds. Signs: oil film on the shaft or loss of damping.
• Clean suspension bolts and torque to specs after every ride. Mud and sand can loosen fasteners.
• Grease all grease fittings (if equipped) after washing. Many aftermarket arms and bushings have zerk fittings.
• Monitor spring sag – if the vehicle sags more than 30% of its free travel, springs are worn.

How to Choose the Right Suspension Parts

When shopping for Can-Am Commander suspension parts, consider these factors:

• Your typical terrain: What works for dunes may be overkill for trails.
• Your budget: A full long-travel kit costs $1,500–$3,000, while just upgrading shocks runs $800–$2,000.
• Compatibility: Ensure parts fit your specific Commander model (Max, XT, or frame size). Check bolt patterns and shock lengths.
• Manufacturer reputation: Brands like Fox, Elka, SuperATV, and Allballs Racing offer proven products with good support.
• Installation difficulty: Some parts (sway bar disconnects) are easy; long-travel arms require mechanical skill and alignment tools.

Final Recommendations

For the average trail rider looking for noticeable improvement, start with a quality set of adjustable shocks and polyurethane bushings. This upgrade alone can transform ride quality without breaking the budget. If you frequently go rock crawling or riding in rough terrain, consider long-travel A-arms to unlock more wheel travel, but be prepared for the added complexity. For desert riders, prioritize high-speed compression shocks and heavier springs to avoid bottoming. Always maintain your suspension properly, and it will serve you for many seasons.

Remember, the best modification is one that aligns with your riding environment. Research each component thoroughly, and don’t hesitate to consult with experienced riders or a trusted mechanic before making major changes.
