Review ZBROZ RACING Aggressive Shock Springs Polaris Pro rmk Le fits RMK 800 2017

The **Zbroz Racing 1315-Z312471-55 Aggressive Shock Springs** are a high-performance upgrade designed specifically for the **2017 Polaris 800 Pro-RMK 174 LE**, delivering a dramatic shift in handling, suspension response, and off-road capability. Engineered with precision, these springs are crafted from premium aircraft-grade aluminum alloy, ensuring exceptional durability and resistance to fatigue even under the most demanding conditions. The aggressive spring rate of **55 lbs/in** provides a noticeably firmer and more responsive ride, allowing the suspension to react instantly to uneven terrain, potholes, and aggressive riding techniques. Unlike stock springs, which prioritize comfort over performance, these Zbroz Racing springs eliminate sag and bottoming out, ensuring optimal wheel travel and consistent contact with the ground. This translates to improved traction, better cornering stability, and a more controlled, athletic feel when navigating technical trails, jumps, or high-speed maneuvers. The aggressive design also reduces unnecessary suspension movement, minimizing energy loss and enhancing overall power transfer to the wheels. Whether tackling rocky descents, fast descents, or aggressive wheelies, these springs transform the 800 Pro-RMK into a more nimble, responsive, and capable off-road machine. Installation is straightforward, requiring only basic tools, and the universal fitment ensures a perfect match for the stock Polaris suspension components. For riders seeking a significant performance boost without sacrificing reliability, the **Zbroz Racing 1315-Z312471-55 Aggressive Shock Springs** are an essential upgrade for those pushing the limits of their Polaris 800 Pro-RMK.

### **Pros and Cons of Buying Zbroz Racing 1315-Z312471-55 Aggressive Shock Springs for 2017 Polaris 800 Pro-RMK**

1. **Improved Ride Quality** Aggressive springs can reduce sag and improve stability, especially on rough terrain, by better controlling suspension movement.

2. **Enhanced Handling** Stiffer springs may reduce body roll and improve cornering performance, making the bike feel more responsive in aggressive riding conditions.

3. **Durability** High-quality springs like those from Zbroz Racing are designed to withstand heavy use, reducing the risk of premature failure compared to stock components.

4. **Customization** These springs offer a more aggressive suspension setup, allowing riders to fine-tune their bike s feel for off-road or high-speed riding.

5. **Compatibility** The part is specifically designed for the 2017 Polaris 800 Pro-RMK, ensuring a proper fit without modification.

6. **Potential for Better Performance** For riders who frequently push their bike s limits, stiffer springs can help maintain control and reduce bottoming out on rough trails.

1. **Harsh Ride on Smooth Terrain** Stiffer springs may make the bike feel less comfortable on paved roads or smooth trails, as they resist compression more aggressively.

2. **Increased Rider Fatigue** A firmer suspension can transmit more vibrations and impacts to the rider, leading to discomfort over long rides.

3. **Potential for Over-Steer or Under-Steer** If not properly tuned with other suspension components (e.g., shocks, fork settings), aggressive springs could lead to instability.

4. **Cost** While not excessively expensive, aftermarket springs are typically more costly than OEM replacements, and installation may require professional labor.

5. **Compatibility Risks** If the springs are not installed correctly or paired with mismatched shocks, they could cause binding or premature wear on other suspension parts.

6. **Limited Use Case** If the rider primarily does light trail riding or prefers a plush, forgiving suspension, these springs may not offer a noticeable benefit and could even detract from the ride.

The **Zbroz Racing 1315-Z312471-55 aggressive shock springs** are a solid upgrade for riders who prioritize **aggressive off-road performance, stability at high speeds, and a firmer suspension feel**. They are well-suited for riders who frequently tackle **rough terrain, jumps, or technical trails** and want to reduce sag while maintaining control.

However, they may **not be ideal** for riders who prefer a **softer, more comfortable ride** on mixed terrain or paved roads. If comfort and vibration dampening are a priority, these springs could make the bike feel harsher than necessary.

Additionally, **proper installation and suspension tuning** are critical these springs should ideally be paired with compatible shocks and adjusted for the rider s weight and riding style to avoid issues like binding or excessive harshness.

---

- **Buy if:** You ride aggressively on rough terrain, want a firmer suspension for better control, and are willing to trade some comfort for performance.

- **Skip if:** You prefer a plush, forgiving ride, mostly ride on smooth trails or pavement, or are unsure about tuning the suspension properly.

- **Consider alternatives:** If you want a middle-ground solution, look for **medium-stiffness aftermarket springs** or **adjustable shocks** that allow you to fine-tune stiffness without committing to a permanent upgrade.

For the best results, **consult with a suspension specialist or Polaris dealer** to ensure proper installation and tuning, especially if you re new to aggressive suspension modifications.
