Review ZBROZ RACING Aggressive Shock Springs Polaris Pro rmk fits RMK 800 2011–2018

The **Zbroz Racing 7533-Z306907-63 Aggressive Shock Springs** are a high-performance, precision-engineered upgrade designed exclusively for the **2011 2018 Polaris 800 Pro-RMK 163**, delivering a dramatic shift in handling, responsiveness, and off-road dominance. Crafted from **high-grade, heat-treated chrome-vanadium steel**, these springs are built to withstand extreme stress while maintaining uncompromising durability, ensuring they outlast standard OEM components by a significant margin. The aggressive spring rate of **63 lbs/in** is meticulously calibrated to maximize suspension travel, allowing the Pro-RMK 163 to absorb rough terrain with precision while maintaining optimal wheel contact and traction. Unlike conventional springs that sacrifice comfort for stiffness, Zbroz s design strikes an ideal balance enhancing articulation on deep ruts, rocks, and uneven trails while still providing a controlled, sporty ride on pavement or smooth terrain. The **close-wound, high-tension coil construction** minimizes sag and rebound, reducing body roll during aggressive cornering and high-speed maneuvers, making the bike feel more planted and responsive in every situation. Whether tackling steep climbs, aggressive descents, or high-speed jumps, these springs eliminate the "bottoming out" issues common with stock setups, allowing riders to push the limits of their Polaris with confidence. Installation is straightforward, requiring only basic tools, and the universal fit ensures compatibility with aftermarket suspension forks and other performance modifications. For riders who demand the ultimate in suspension performance, the Zbroz Racing 7533-Z306907-63 springs are the definitive choice transforming the Pro-RMK 163 into a true off-road weapon capable of conquering even the most demanding trails with effortless control.

### **Pros and Cons of Buying Zbroz Racing 7533-Z306907-63 Aggressive Shock Springs for 2011-2018 Polaris 800 Pro-RMK (163)**

#### **Pros:**

1. **Improved Ride Quality and Comfort** Aggressive springs can reduce bottoming out and improve suspension response, especially on rough terrain, by maintaining better tire contact with the ground.

2. **Enhanced Handling and Stability** The stiffer springs may help reduce body roll and improve cornering performance, making the bike feel more planted and responsive.

3. **Better Weight Distribution** Aggressive springs can help shift weight more efficiently, which may improve traction and handling in aggressive riding conditions.

4. **Compatibility with Aftermarket Suspension Tuning** If you plan to modify other suspension components (e.g., shocks, linkages), these springs can serve as a solid foundation for further adjustments.

5. **Durability** Zbroz Racing is a reputable brand known for high-quality, long-lasting components, reducing the risk of premature failure.

6. **Easy Installation** These springs are designed as direct replacements for OEM parts, meaning they should fit without extensive modifications.

7. **Performance Gains for Off-Road Use** If you frequently ride on rough trails or in aggressive conditions, these springs can help maintain better suspension travel and control.

#### **Cons:**

1. **Potential Ride Harshness** Aggressive springs can make the bike feel stiffer and less forgiving, especially on smooth roads or in relaxed riding conditions. This may lead to increased fatigue over long rides.

2. **Reduced Comfort on Rough Terrain** While they may prevent bottoming out, they can also make bumps and uneven surfaces feel harsher, leading to a less comfortable ride.

3. **Possible Over-Steer or Instability** If the springs are too stiff for your riding style or weight, they could make the bike feel twitchy or difficult to control, particularly at high speeds or in tight turns.

4. **Compatibility Concerns** Ensure these springs are the correct fit for your specific model (2011-2018 Polaris 800 Pro-RMK 163). Mismatched springs could lead to poor performance or damage.

5. **Cost** While not excessively expensive, aftermarket springs are typically more costly than OEM parts, and if they don t suit your riding style, the investment may feel unnecessary.

6. **Requires Adjustment** If you re not experienced with suspension tuning, you may need to experiment with sag adjustments or other modifications to get the best results.

7. **Potential Voiding of Warranty** Modifying suspension components may void the manufacturer s warranty, so consider this if your bike is still under warranty.

### **Conclusion and Recommendation**

The **Zbroz Racing 7533-Z306907-63 aggressive shock springs** are a solid choice if you prioritize **performance, stability, and aggressive off-road riding** over extreme comfort. They are well-suited for riders who frequently tackle rough terrain, need better handling, or are already tuning their suspension for performance.

However, if you primarily ride on paved roads, smooth trails, or prefer a plush, comfortable ride, these springs may feel too stiff and could detract from your enjoyment. In such cases, **lighter or stock springs** might be a better fit.

**Recommendation:**

- **Buy them if:** You ride aggressively off-road, want improved handling, and are willing to sacrifice some comfort for performance. Pair them with proper sag adjustments and consider other suspension tweaks (e.g., shock valving) for optimal results.

- **Skip them if:** You mostly ride on smooth terrain, prioritize comfort, or are unsure about suspension tuning. In that case, stick with OEM springs or consider a milder aftermarket option.

- **Test before committing:** If possible, borrow or rent a bike with similar springs to see if the stiffness aligns with your preferences before making a purchase.

Ultimately, suspension tuning is highly subjective what works for one rider may not suit another. Always test changes gradually and adjust based on your riding conditions and comfort.
