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

The **Zbroz Racing 9956-Z311753-56 Aggressive Shock Springs** are a high-performance upgrade designed specifically for the **2011 2018 Polaris 800 Pro-RMK 155**, delivering a dramatic shift in handling, responsiveness, and off-road capability. Engineered with precision, these springs are crafted from **high-grade, heat-treated steel** to ensure unmatched durability and resistance to fatigue, even under the most demanding conditions. Unlike stock suspension components, which prioritize comfort and stability over aggressive performance, the Zbroz Racing springs are tuned to **lower the ride height**, sharpen the bike s cornering ability, and enhance articulation over rough terrain. This aggressive tuning allows the Pro-RMK 155 to maintain better traction in tight turns, absorb impacts more efficiently, and provide a more connected, sporty feel ideal for riders pushing the limits on trails, rock gardens, or competitive racing circuits. The springs are **pre-loaded and pre-tensioned** to eliminate sag and ensure immediate engagement with the suspension system, reducing wheel hop and improving overall stability at high speeds. Whether tackling deep ruts, steep climbs, or aggressive descents, these springs transform the 800 Pro-RMK 155 into a more nimble, responsive machine, making them a must-have for riders seeking a competitive edge. Built to withstand extreme stress, the Zbroz Racing springs are backed by a reputation for reliability, ensuring they remain a trusted choice for serious off-road enthusiasts who demand nothing less than peak performance.

### **Pros and Cons of Buying Zbroz Racing 9956-Z311753-56 Aggressive Shock Springs for 2011 2018 Polaris 800 Pro-RMK 155**

#### **Pros:**

1. **Improved Ride Quality** These aggressive springs are designed to reduce sag and improve suspension response, leading to a firmer, more controlled ride, especially on rough terrain. They can help eliminate bottoming out on jumps or rough trails.

2. **Enhanced Performance** The stiffer spring rate provides better wheel travel control, which can improve handling, stability, and cornering performance. This is particularly useful for riders who frequently ride at high speeds or on technical trails.

3. **Durability** Zbroz Racing is known for producing high-quality, durable suspension components. These springs are built to withstand the stresses of off-road use, reducing the risk of premature failure.

4. **Compatibility** The part number (9956-Z311753-56) is specifically designed for the 2011 2018 Polaris 800 Pro-RMK 155, ensuring a proper fit without modification. This reduces the risk of installation issues.

5. **Aftermarket Support** Zbroz Racing is a reputable brand with a strong presence in the off-road community. They offer technical support, and their parts are widely available through dealers and online retailers.

6. **Customization Option** If you later decide to adjust your suspension, these springs can be paired with other aftermarket components (e.g., Zbroz shocks, rebound dampeners) for further tuning.

7. **Cost-Effective Upgrade** Compared to full suspension rebuilds or premium aftermarket shocks, these springs are a relatively affordable way to improve suspension performance without a major investment.

#### **Cons:**

1. **Stiffer Ride Feel** The aggressive spring rate will make the bike feel firmer and less forgiving on rough terrain. If you prefer a plush, cushioned ride, this upgrade may feel harsh, especially on washboard or rocky trails.

2. **Potential for Over-Steer or Instability** A stiffer spring can reduce the suspension s ability to absorb bumps quickly, which may lead to a less stable feel at high speeds or in aggressive riding conditions. Some riders may experience a slight loss of traction or handling precision.

3. **Wear on Other Components** Stiffer springs increase stress on the suspension linkages, bushings, and frame. Over time, this could accelerate wear on these parts, potentially requiring more frequent maintenance or replacement.

4. **Not a Complete Solution** While these springs improve stiffness, they do not address issues like worn shocks, improper sag settings, or damaged linkages. If your suspension is already degraded, simply adding stiffer springs may not resolve underlying problems.

5. **Installation Complexity** Replacing shock springs requires removing the shock from the bike, which can be time-consuming and may require some mechanical skill. If you re not comfortable with suspension work, you may need to pay a mechanic for installation.

6. **Limited Adjustability** Unlike shocks with adjustable rebound or compression damping, these springs offer no tuning options. If you later find the stiffness too extreme or too mild, you ll need to replace them entirely.

7. **Potential for Sag Issues** If the springs are too stiff for your riding style or weight, the bike may sit too high off the ground, reducing ground clearance and making the ride feel unstable on rough terrain.

### **Conclusion**

The **Zbroz Racing 9956-Z311753-56 aggressive shock springs** are a solid aftermarket upgrade for the 2011 2018 Polaris 800 Pro-RMK 155, particularly for riders who prioritize performance, stability, and reduced sag. They offer noticeable improvements in handling and control, especially for those who ride aggressively or at high speeds. However, they come with trade-offs, including a firmer ride feel, potential instability on rough terrain, and increased stress on other suspension components.

If you currently experience bottoming out, excessive sag, or a soft suspension feel, these springs will likely provide a meaningful upgrade. Conversely, if you prefer a plush, comfortable ride or primarily ride on smooth trails, the benefits may not justify the change.

---

### **Recommendation**

- **Install if:** You frequently ride at high speeds, take jumps, or notice your suspension bottoming out. You want a firmer, more responsive ride and are willing to accept a slightly harsher feel in exchange for better control.

- **Avoid if:** You prefer a soft, cushioned ride or mostly ride on smooth trails. You also have worn suspension components (shocks, linkages) that would benefit from a full rebuild before upgrading springs.

- **Consider pairing with:** Zbroz Racing shocks or rebound dampeners for a more comprehensive suspension upgrade. Ensure proper sag settings are maintained after installation.

- **Alternative options:** If you re unsure about the stiffness, consider starting with a **moderate stiffness spring** (e.g., Zbroz s "standard" or "intermediate" options) before committing to the aggressive version.

For best results, **consult a suspension specialist or experienced mechanic** to verify your current sag settings and ensure the springs are the right choice for your riding style. If you re new to suspension modifications, test the upgrade on a controlled trail before committing to full-time use.
