The **Sports 8137-S416115-37 SPI Gas Slide Shock** is a high-performance, OEM-replacement rear suspension component designed specifically for the **2001-2002 Arctic Cat ZR 800**, ensuring optimal handling, durability, and off-road capability. Engineered with **SPI (Sealed Power Injection) technology**, this gas-charged shock absorber delivers superior damping performance by maintaining consistent pressure and minimizing air compression, which translates to a smoother, more responsive ride over rough terrain. The shock features a **high-quality, durable construction**, incorporating a **double-tube design** with a **nitrogen-charged gas spring** that provides consistent support and reduces sag, even under heavy loads. This ensures that the rear suspension remains firm and responsive, whether you're tackling steep climbs, navigating tight trails, or carrying extra weight for extended rides. The **OEM-fitment** guarantees a precise match to the ZR 800 s suspension geometry, eliminating the need for adjustments while maximizing stability and control. Built to withstand the demands of aggressive off-roading, this shock is constructed from **corrosion-resistant materials**, including a **chrome-plated rod** and **high-grade steel components**, ensuring longevity even in harsh conditions. Whether you're pushing the limits on technical trails or simply seeking a more refined ride, the **Sports 8137-S416115-37 SPI Gas Slide Shock** delivers the performance and reliability needed to keep your Arctic Cat ZR 800 at its best.
### **Pros and Cons of buying a Sports 8137-S416115-37 SPI Gas Slide Shock for a 2001-2002 Arctic Cat ZR 800 Rear**
#### **Pros:**1. **Improved Ride Comfort** Gas shocks like this one absorb bumps and vibrations better than traditional coil springs, reducing fatigue during long rides.
2. **Better Handling and Stability** The SPI (Selective Positioning Interface) technology allows for precise tuning, enhancing cornering grip and reducing body roll.
3. **Longer Lifespan** Gas shocks are less prone to oil leaks and rust compared to older coil-over shocks, especially in varying weather conditions.
4. **Adjustable Preload** Some versions of this shock allow for compression preload adjustment, letting you fine-tune stiffness for different riding styles (aggressive vs. cruising).
5. **OEM Replacement Fitment** This is a direct replacement for the stock rear shock, ensuring proper alignment and compatibility without modification.
6. **Durability** The sealed gas design resists air compression loss over time, maintaining consistent performance longer than open-shock systems.
7. **Reduced Maintenance** Unlike coil springs, gas shocks don t require periodic lubrication or tension adjustments.
#### **Cons:**1. **Cost** This is a premium aftermarket part, significantly more expensive than basic coil-over shocks or even OEM replacements.
2. **Installation Complexity** Requires proper alignment and torque specifications; improper installation can lead to handling issues or premature wear.
3. **Potential for Overkill** If you primarily ride on smooth trails or don t push the bike aggressively, the benefits may not justify the expense.
4. **Limited Adjustability (on some models)** While SPI shocks offer tuning, not all versions allow for full compression/damping adjustments, which could be a drawback for riders who want fine-tuned suspension.
5. **Weight** Gas shocks are heavier than coil springs, which could slightly affect acceleration (though the difference is minimal on a ZR 800).
6. **Compatibility Concerns** Ensure the shock s mounting points match your bike s frame exactly; minor discrepancies could cause clearance issues with the swingarm or fenders.
7. **Resale Impact** While improving ride quality, aftermarket shocks may not appeal to all buyers, potentially affecting resale value slightly.

### **Conclusion:**The **Sports 8137-S416115-37 SPI Gas Slide Shock** is a high-quality upgrade for a 2001-2002 Arctic Cat ZR 800, offering noticeable improvements in comfort, handling, and durability. It s particularly beneficial for riders who prioritize smoothness, stability, and long-term reliability over cost savings. However, the significant upfront cost and potential overkill for mild riders are valid considerations.
If you frequently ride on rough terrain, take sharp corners, or want a more refined ride, this shock is a worthwhile investment. For casual riders or those on a tight budget, a high-quality OEM replacement or a more affordable aftermarket coil-over shock might suffice.
