Review KAWASAKI Snowmobile Left Hand Rear Suspension Bracket Drifter fits 1980–1981

The **Kawasaki 39020-3503 Left Rear Suspension Bracket** is a meticulously crafted, high-performance component designed exclusively for the **1980-1981 Kawasaki Drifter**, a legendary motorcycle known for its aggressive styling, nimble handling, and timeless appeal. This bracket serves as a critical structural element of the rear suspension system, anchoring the swingarm and shock absorber assembly to the frame while ensuring precise alignment and durability under the demands of spirited riding. Crafted from high-grade steel, this bracket is engineered to withstand the rigors of daily use, from cruising on open highways to tackling tight, technical trails, all while maintaining the Drifter s signature balance between comfort and sportiness. The **39020-3503** part number identifies it as a left-side component, distinguishing it from its right-side counterpart and ensuring a perfect fit when paired with the matching right rear suspension bracket. Its robust construction not only enhances the motorcycle s structural integrity but also contributes to the Drifter s iconic, muscular stance, reinforcing the frame s rigidity where it matters most. Whether restoring a classic Drifter to its original glory or upgrading an existing bike for improved performance, this suspension bracket is an essential part that bridges form and function, embodying Kawasaki s commitment to both heritage and innovation.

**Pros and Cons of buying a Kawasaki 39020-3503 Left Rear Suspension Bracket (80-81 Drifter)**

### **Pros:**

1. **Direct Fitment** This part is specifically designed for the 1980 and 1981 Kawasaki Drifter models, ensuring compatibility without modification. This eliminates the need for custom fabrication or aftermarket adjustments.

2. **Authentic Replacement** Purchasing an OEM or high-quality aftermarket part ensures that the suspension bracket will match the original specifications, maintaining the bike s handling and ride quality. This is particularly important for maintaining the bike s structural integrity and alignment.

3. **Reliability** Kawasaki parts, especially OEM or reputable aftermarket replicas, are built to withstand the stresses of daily riding. A well-made suspension bracket reduces the risk of premature failure, which could lead to handling issues or accidents.

4. **Ease of Installation** Since this is a common part for the Drifter, many mechanics and riders have experience installing it. The process typically involves removing the rear wheel, disconnecting the swingarm, and replacing the bracket, which can be done with basic tools. Instructions are widely available online.

5. **Cost-Effective for Long-Term Use** While the upfront cost may seem high, replacing a worn or damaged suspension bracket prevents more expensive issues down the line, such as damaged swingarms, axle housings, or suspension components. It also avoids the hassle of searching for rare parts if the bracket fails completely.

6. **Improved Safety** A functioning suspension bracket is critical for proper rear suspension operation. A faulty bracket can lead to uneven wheel alignment, poor shock absorption, or even sudden detachment, which poses a significant safety risk. Replacing it ensures the bike remains safe to ride.

7. **Preservation of Value** If you plan to sell or restore the Drifter in the future, maintaining original or high-quality aftermarket parts preserves its value. A complete and well-preserved suspension system is attractive to collectors and enthusiasts.

### **Cons:**

1. **Limited Availability** OEM Kawasaki parts for older models like the Drifter can be difficult to find, especially if the bike is no longer in production. You may need to source the part from specialty motorcycle dealers, online marketplaces, or eBay, which could involve shipping delays or higher prices.

2. **Potential for Counterfeit Parts** If purchasing from third-party sellers, there is a risk of receiving a counterfeit or low-quality replica. These parts may not fit correctly, could fail prematurely, or may not meet safety standards. Always verify the seller s reputation and check for authenticity markings.

3. **Additional Labor Costs** If you lack mechanical experience, installing the bracket may require professional labor. Labor costs can add up, especially if the bike needs additional work (e.g., alignment, brake adjustments) after the installation.

4. **Compatibility Concerns** While this part is designed for the 80-81 Drifter, slight variations in later models or custom builds might require additional modifications. Double-checking the part number and model year compatibility is essential to avoid mismatches.

5. **Cost** Depending on whether you buy OEM or aftermarket, the price can range from moderate to high. For enthusiasts on a tight budget, this may be a significant expense, especially if other suspension components (e.g., shocks, linkages) also need replacement.

6. **Time-Consuming Installation** Replacing the rear suspension bracket involves disassembling parts of the rear end, which can be time-consuming. Riders with busy schedules may find the process inconvenient, particularly if they lack the necessary tools or workspace.

7. **Risk of Hidden Damage** If the bracket is being replaced due to an accident or wear, there may be underlying damage to other components (e.g., swingarm, axle housing, or suspension links). Inspecting these parts during installation is crucial to avoid future issues.

### **Conclusion:**

The Kawasaki 39020-3503 left rear suspension bracket is a critical and highly recommended replacement for 1980 and 1981 Drifter owners experiencing suspension issues. The benefits of reliability, safety, and proper fitment far outweigh the potential drawbacks, provided you source the part from a trusted supplier and ensure proper installation. The cons such as availability, cost, or installation complexity are manageable with careful planning and research.

If you are experiencing rear suspension problems (e.g., rattling, misalignment, or poor handling), replacing this bracket is a proactive step to restore the bike s performance and safety. For those on a budget, prioritize other suspension components (e.g., shocks, bushings) if this bracket is in good condition, but if it is visibly damaged or worn, replacement is strongly advised.

---

### **Recommendation:**

1. **Verify the Part Number and Model Year** Confirm that the 39020-3503 bracket is the correct fit for your Drifter. Cross-reference with your bike s build year and any modifications.

2. **Source from a Reputable Supplier** Purchase from a trusted dealer, Kawasaki-approved parts distributor, or a well-reviewed online seller (e.g., Cycle World, Iron Horse, or eBay with verified feedback). Avoid untested or suspiciously cheap options.

3. **Inspect Other Suspension Components** While replacing the bracket, check the swingarm, axle housing, shocks, and linkages for wear. Address any issues to prevent future problems.

4. **Consider Professional Installation** If you are not experienced with motorcycle suspension work, have a mechanic perform the installation to ensure proper alignment and torque specifications.

5. **Budget for Additional Costs** Account for labor (if applicable), tools, and potential follow-up repairs. While the bracket itself is a one-time fix, it prevents more costly damage down the road.

6. **Document the Process** Take photos or videos during installation for reference if you need to troubleshoot later. This also helps when selling or restoring the bike.

**Final Verdict:** **Buy the part if your Drifter s rear suspension bracket is damaged or worn.** The long-term benefits of safety, reliability, and proper handling justify the investment. Treat it as a necessary maintenance step rather than an optional upgrade.
