Review ARCTIC CAT 6000 8000 Tri hub Inch Rear Axle Wheel fits THUNDERCAT ZR XF RR 2017–2020

The **Arctic Cat 4604-137 3604-640 ZR 6000/8000 XF Tri-Hub Rear Axle Wheel** is a premium, high-performance off-road component designed exclusively for Arctic Cat s legendary **Thundercat** series of snowmobiles, specifically tailored for the **ZR 6000 and 8000 XF models**. Engineered with precision and built to withstand the harshest winter conditions, this rear axle wheel is a critical upgrade for riders seeking enhanced durability, superior traction, and a refined ride experience. Crafted from **high-grade, heat-treated steel**, the wheel features a **tri-hub design**, a signature Arctic Cat innovation that distributes weight more evenly across the axle, reducing stress on the drivetrain and improving overall stability. This design also allows for better articulation under heavy loads, ensuring smoother operation when navigating deep snow, ice, or rough terrain. The wheel is compatible with **19-inch, 18-inch, 17-inch, and 20-inch rims**, providing versatility for riders who may switch between different tire sizes or prefer a customized fit for their specific riding style or snow conditions. The robust construction minimizes flex, enhancing power transfer and reducing the risk of fatigue or failure, even during prolonged use in extreme environments. Whether tackling steep climbs, tight turns, or long-distance cruising, this axle wheel delivers the strength and reliability required to maintain peak performance. Arctic Cat s meticulous attention to detail ensures that every component, from the **precision-machined hubs to the reinforced mounting points**, is engineered to seamlessly integrate with the Thundercat s advanced suspension and drivetrain systems. For riders who demand nothing less than the best in off-road capability, the **4604-137 3604-640 Tri-Hub Rear Axle Wheel** is an essential upgrade that elevates both the functionality and longevity of their snowmobile, ensuring a thrilling yet trouble-free experience on and off the trail.

### **Pros and Cons of buying a Arctic Cat 4604-137 / 3604-640 ZR 6000 / 8000 XF Tri-Hub Rear Axle Wheel (19", 18", 17", 20" ThunderCat)**

#### **Pros**

1. **Durability and Strength** The tri-hub design distributes weight evenly across three hubs, reducing stress on individual components. This makes the wheel more resistant to bending or warping under heavy loads, especially in off-road or heavy-duty applications.

2. **Compatibility with Arctic Cat Models** These wheels are specifically engineered for Arctic Cat s 6000 and 8000 XF series, ensuring a proper fit with the factory mounting points. This reduces the risk of alignment issues or premature wear.

3. **Lightweight Construction** While still robust, the wheels are made from high-strength aluminum, which is lighter than steel. This can improve fuel efficiency and handling, particularly on larger, heavier ATVs.

4. **Off-Road Performance** The ThunderCat series is designed for rugged use, with reinforced structures to handle rocks, mud, and rough terrain without excessive flexing or damage.

5. **Aftermarket Support** Arctic Cat s wheels are widely available through dealers and online retailers, and there is a strong aftermarket presence for replacements, upgrades, and accessories.

6. **Long-Term Reliability** The tri-hub design is less prone to catastrophic failure compared to single-hub or dual-hub setups, which can bend or crack under extreme stress.

7. **Aesthetic Appeal** The ThunderCat wheels have a sleek, aggressive look that enhances the sporty appearance of Arctic Cat ATVs, appealing to owners who prioritize style.

8. **Warranty Coverage** Arctic Cat typically offers warranties on their wheels, providing peace of mind against manufacturing defects.

#### **Cons**

1. **Cost** These wheels are more expensive than standard OEM wheels, especially when purchasing a full set. The price can be a significant upfront investment for owners on a budget.

2. **Specialized Fitment** While designed for Arctic Cat 6000/8000 XF models, they may not fit other brands or even older Arctic Cat models without modifications. This limits versatility.

3. **Weight Distribution Concerns** While the tri-hub design is strong, improper loading (e.g., carrying excessive weight on one side) can still stress the wheel. Owners must ensure balanced weight distribution.

4. **Potential for Overkill** For casual riders who mostly use their ATV on smooth trails or light off-roading, the extra strength of these wheels may be unnecessary, making them a less cost-effective choice.

5. **Maintenance Requirements** High-performance wheels may require more frequent inspections for wear, bolt torque, and alignment, especially after rough rides.

6. **Limited Customization** Unlike some aftermarket wheels, these are not designed for extreme modifications (e.g., oversized tires or heavy lifts), which could void warranties or cause compatibility issues.

7. **Resale Value Impact** While durable, these wheels may not retain their value as well as OEM wheels, especially if the ATV is sold used.

8. **Potential for Overheating in Extreme Conditions** In very hot climates or during prolonged heavy use, the aluminum construction may heat up more than steel wheels, though this is rare with proper maintenance.

### **Conclusion and Recommendation**

The **Arctic Cat 4604-137 / 3604-640 ZR ThunderCat tri-hub wheels** are among the best aftermarket upgrades for Arctic Cat 6000 and 8000 XF series ATVs, offering superior durability, off-road capability, and a premium look. They are ideal for **serious riders, heavy-duty users, or those who frequently push their ATVs beyond standard conditions** such as hauling trailers, riding in extreme terrain, or participating in competitive events.

However, they are **not necessary for casual riders** who primarily use their ATVs on well-maintained trails or for light recreational use. In such cases, the higher cost may not justify the benefits, and OEM or mid-range aftermarket wheels could suffice.

- You own an Arctic Cat 6000 or 8000 XF and want the best possible wheel for durability and performance.

- You frequently ride in harsh conditions (rocks, deep mud, heavy loads).

- You prioritize a premium, long-lasting wheel that reduces the risk of failure.

- You are willing to invest in performance upgrades for your ATV.

- You are on a tight budget and only need basic off-road capability.

- Your riding style is mostly light or on smooth terrain.

- You plan to sell the ATV soon, as the wheels may not add significant resale value.

- You intend to modify the ATV with extreme lifts or heavy loads that could void warranties.

For most **heavy-use Arctic Cat owners**, these wheels are a worthwhile investment. For others, a more budget-friendly alternative (such as Arctic Cat s standard wheels or other reputable aftermarket brands) may be a better fit. Always ensure proper installation and maintenance to maximize their lifespan.
