Review HARLEY DAVIDSON Nos Lower Slide Bushing 39mm Fork

The **Harley-Davidson 45465-87 NOS Lower Slide Bushing (39mm Fork, Part Number 45465-07)** is a meticulously crafted, high-performance component designed to enhance the ride quality, handling, and longevity of Harley-Davidson s classic and modern forks, particularly those in the 39mm diameter range. This **new-old-stock (NOS)** lower slide bushing represents a premium upgrade for riders seeking to restore factory precision or improve suspension performance in their Harley-Davidson motorcycles, including models like the Sportster, Softail, or Dyna series. Engineered from durable, high-grade **polyurethane or rubber** (depending on the specific variant), this bushing is precision-molded to fit seamlessly within the lower slide assembly, reducing friction, minimizing wear, and ensuring smooth articulation of the fork s sliding components. The **original equipment quality** of this part guarantees a tight, interference-free fit, allowing the fork to operate with optimal responsiveness and damping efficiency critical for both on-road comfort and off-road adaptability. Whether you re restoring a vintage Harley to its original specifications or fine-tuning a modern bike for superior handling, this bushing is an essential component for maintaining the fork s structural integrity and performance. Its **authentic Harley-Davidson compatibility** ensures seamless integration with the bike s suspension system, while its **new condition** (when sourced as NOS) eliminates concerns about degraded materials or premature failure. For enthusiasts and mechanics alike, this part is a testament to Harley-Davidson s commitment to durability and performance, offering a straightforward yet impactful solution for those looking to preserve or elevate their motorcycle s ride dynamics.

### **Pros and Cons of buying a Harley-Davidson 45465-87 NOS Lower Slide Bushing (39mm Fork, Part 45465-07)**

1. **New Old Stock (NOS) Quality** Since this part is NOS, it is unopened and in original condition, ensuring it has not been exposed to wear or damage from previous use. This means it should perform as if brand new, reducing the risk of premature failure.

2. **Direct Fitment** The part number (45465-07) is specific to Harley-Davidson s 39mm fork lower slide bushings, meaning it is designed to fit perfectly without modification. This eliminates the need for custom machining or adjustments.

3. **Reliability** Harley-Davidson parts, especially those from their original stock, are built to withstand the stresses of motorcycle use. A properly functioning lower slide bushing ensures smooth fork operation, reducing vibration and improving handling.

4. **Prevents Fork Damage** Worn or damaged lower slide bushings can cause excessive play in the fork, leading to binding, uneven suspension, and even fork tube damage. Replacing this part can restore proper fork function and extend the life of the suspension components.

5. **Easier Maintenance** Since this is a single part replacement, it is a straightforward upgrade compared to overhauling the entire fork. It can be installed by a mechanic or a skilled DIY rider with basic tools.

6. **Cost-Effective for Long-Term Use** While the upfront cost may seem high, replacing a worn bushing prevents more expensive fork damage down the line. It is a preventive maintenance measure that saves money in the long run.

7. **Authentic Harley-Davidson Build** If you value original equipment quality, NOS parts like this maintain the authenticity of your bike s construction, which can be important for enthusiasts who prefer OEM components.

---

1. **High Cost** Harley-Davidson parts, especially NOS items, can be expensive. The price may be prohibitive for riders on a tight budget, particularly if they need multiple parts or have other maintenance needs.

2. **Limited Availability** NOS parts may not always be in stock, especially for older or discontinued models. You may need to wait for restocking or purchase from a secondary seller, which could increase the price.

3. **Installation Complexity** While replacing a lower slide bushing is simpler than a full fork rebuild, it still requires disassembling the fork, which can be tricky for inexperienced riders. Improper installation could lead to damage or premature wear.

4. **Potential for Counterfeit Parts** Since NOS parts are valuable, there is a risk of purchasing counterfeit or refurbished parts disguised as NOS. Always verify the seller s reputation and authenticity before buying.

5. **Not a Permanent Fix for All Issues** If the fork has other problems (e.g., worn seals, damaged stanchions, or misaligned components), replacing just the bushing may not fully resolve suspension issues. A full fork service might be necessary for optimal performance.

6. **Time-Consuming** Fork disassembly and reassembly can take several hours, especially if you are unfamiliar with the process. This may require scheduling time off or hiring a mechanic, adding to the overall cost.

7. **Environmental and Ethical Concerns** If you prioritize sustainability, purchasing a single NOS part may not be the most eco-friendly option, as it contributes to waste from unused packaging and potential overproduction of spare parts.

The Harley-Davidson 45465-87 NOS lower slide bushing (39mm fork) is a high-quality, direct-fit replacement that offers significant benefits for maintaining or restoring your bike s suspension performance. Its unopened condition ensures reliability, and replacing a worn bushing can prevent more costly fork damage. However, the high cost, potential availability issues, and the technical skill required for installation are drawbacks that must be considered.

If you are experiencing fork binding, uneven handling, or excessive play in your suspension, this part is a worthwhile investment for long-term bike health. On the other hand, if budget constraints or lack of mechanical experience are concerns, weigh the cost against the potential savings from avoiding fork damage. For most serious riders who prioritize performance and longevity, the pros outweigh the cons.

---

- **Buy if:** You are experiencing fork-related issues (e.g., binding, uneven suspension), you have the budget for a quality NOS part, and you are either comfortable installing it yourself or have access to a trusted mechanic. This part is ideal for riders who want to maintain their bike s original specifications and avoid suspension-related failures.

- **Avoid if:** You are on a tight budget, the part is difficult to source, or you lack the time/skills to install it properly. In such cases, consider a refurbished part (if available) or a full fork service to address all potential issues at once.

- **Additional Tip:** If you are unsure about the condition of your fork, have a mechanic inspect it first. They can confirm whether the bushing is the sole issue or if other components (e.g., seals, springs) need attention. Always purchase from a reputable dealer to ensure authenticity.
