The **SP1 6679-S395199-19 suspension spring** is a precision-engineered, high-performance replacement part designed specifically for the **rear left suspension** of **Polaris Sport models** manufactured between **1989 and 1996**. Crafted from **high-grade, heat-treated chrome-vanadium steel**, this spring is built to withstand the rigorous demands of off-road riding, delivering consistent performance and durability even under extreme conditions. The spring features a **tight coil winding and uniform pitch**, ensuring optimal load distribution and minimizing fatigue over time, which is crucial for maintaining ride quality and handling on rough terrain.

### Pros and Cons of buying a SP1 6679-S395199-19 Suspension Spring for a 1989 1996 Polaris Sport (Rear Left)

1. **OEM Replacement Part** This spring is an original equipment manufacturer (OEM) part, meaning it is designed to match the specifications of your Polaris Sport s factory suspension. This ensures compatibility, performance, and longevity similar to the original component.

2. **Improved Ride Comfort** If the original spring is worn or sagging, replacing it with a new OEM spring can restore proper suspension function, leading to a smoother ride, better handling, and reduced fatigue during long rides.

3. **Enhanced Handling and Stability** A properly functioning rear suspension spring helps maintain wheel contact with the ground, improving traction, cornering, and overall control especially important for off-road or aggressive riding.

4. **Prevents Further Damage** A failing spring can cause excessive wear on other suspension components, such as shocks, bushings, or the frame. Replacing it early can prevent costly damage to these parts.

5. **Reliability** OEM parts are built to withstand the stresses of off-road use, reducing the risk of sudden failure during a ride.

6. **Easy Installation** As a direct replacement, this spring should fit without modification, making it a straightforward upgrade for DIYers or mechanics.

7. **Warranty Coverage** If purchased from a reputable dealer or supplier, the spring may come with a warranty, providing peace of mind against defects.

1. **Cost** OEM parts can be more expensive than aftermarket alternatives, especially if sourced directly from Polaris or authorized dealers. The price may be higher than generic or third-party suspension springs.

2. **Limited Customization** Unlike aftermarket springs, which may offer stiffer or softer options for tuning ride quality, OEM springs provide no flexibility in adjusting suspension characteristics to personal preferences.

3. **Potential Availability Issues** Depending on the supplier, OEM parts may not always be in stock, requiring additional time or effort to locate. Some older Polaris models may have discontinued parts, though this spring appears to be widely available.

4. **Wear and Tear Over Time** Even an OEM spring will degrade with age and use. While it may last longer than a worn-out original, it will eventually need replacement again, depending on riding conditions and maintenance.

5. **Installation Skill Required** While straightforward, replacing a suspension spring may require basic mechanical skills, tools, and access to a lift or sturdy stand. Improper installation could lead to safety issues or premature failure.

6. **No Performance Upgrades** If you re looking to modify your bike for aggressive off-roading or racing, OEM springs may not provide the extra stiffness or responsiveness of aftermarket options designed for those purposes.

The **SP1 6679-S395199-19 suspension spring** is a reliable and high-quality choice for restoring your 1989 1996 Polaris Sport s rear suspension to factory specifications. It offers the benefits of OEM reliability, improved ride quality, and compatibility, making it an ideal replacement for worn or damaged springs. However, the higher cost and lack of customization options may deter those seeking aftermarket performance upgrades.

If your primary goal is **restoring functionality, safety, and comfort** without altering the bike s stock characteristics, this is an excellent and practical choice. For riders looking to **modify suspension stiffness or performance**, exploring aftermarket alternatives may be worth considering.

- **Buy the OEM spring** if you prioritize **reliability, ease of installation, and a direct replacement** that matches your bike s original specifications.

- **Consider aftermarket options** (e.g., stiffer or softer springs) if you want to **customize ride feel** for specific terrains or riding styles.

- **Inspect other suspension components** (shocks, bushings, frame) during installation to ensure they are in good condition, as worn parts can affect performance.

- **Purchase from a trusted supplier** (e.g., Polaris dealership, reputable online retailers like Amazon, or specialty ATV parts stores) to ensure authenticity and warranty coverage.

For most riders maintaining a stock or near-stock setup, this spring is a **solid and recommended choice**.
