Review KAWASAKI Zx-7r/zx-7 Crankshaft Bushing Black #2 Nos fits ZX-7R ZX-7

The **Kawasaki 92028-1630 ZX-7R/ZX-7 Crankshaft Bushing (NOS)** is a high-performance, factory-specification component designed to ensure optimal engine function and longevity in Kawasaki s legendary ZX-7R and ZX-7 models. This **new-old-stock (NOS)** bushing is a precision-engineered, machined part that fits seamlessly into the crankshaft housing, providing critical support and alignment for the crankshaft assembly. Crafted from high-grade, wear-resistant materials, it is engineered to withstand the extreme stresses of high-revving, high-performance riding, delivering smooth operation and minimizing friction within the engine s internal mechanics. The bushing s tight tolerances and durable construction ensure that it maintains its integrity even under the demanding conditions of aggressive throttle inputs, aggressive riding styles, or aftermarket modifications, such as increased displacement or forced induction. Whether used in stock applications or as part of a rebuild, this bushing is a vital component for preserving the engine s efficiency, reducing the risk of premature wear, and maintaining the ZX-7 s reputation for reliability and power. Its compatibility with both the **ZX-7R (1998 2004)** and **ZX-7 (1996 1997)** models makes it an essential replacement for mechanics and enthusiasts seeking to restore or enhance the performance of these iconic sportbikes. With its stock specifications and pristine condition, this NOS bushing is a trusted choice for those who demand nothing less than factory-level quality in their restoration or maintenance projects.

### **Pros and Cons of buying a Kawasaki 92028-1630 ZX-7R/ZX-7 Crankshaft Bushing (NOS)**

1. **Original Equipment Quality (OEM)** The part is new-old-stock (NOS), meaning it is factory-fresh and has not been installed or used. This ensures it meets Kawasaki s original specifications and quality standards, reducing the risk of premature wear or failure.

2. **Direct Fitment** Designed specifically for the ZX-7R/ZX-7 engine, this bushing is engineered to match the exact dimensions and tolerances required for proper crankshaft alignment and smooth operation. No modifications or additional machining are typically needed.

3. **Durability and Longevity** Kawasaki uses high-quality materials in their OEM components, which are built to withstand the stresses of high-performance riding. A properly installed NOS bushing should last the lifespan of the engine if maintained correctly.

4. **Reliability** Since it is a genuine part, it eliminates concerns about aftermarket knockoffs that may fail prematurely or introduce compatibility issues. This is particularly important for critical components like crankshaft bushings, which affect engine stability.

5. **Warranty Coverage** If purchased directly from Kawasaki or an authorized dealer, the part may still come with warranty protection, offering recourse in case of defects. Third-party sellers may not provide this, so verification is necessary.

6. **Preservation of Engine Performance** A worn or damaged crankshaft bushing can lead to excessive play, vibration, or even catastrophic failure (e.g., crankshaft damage). Replacing it with a NOS part restores the engine to its intended performance and reliability.

7. **Ease of Installation** As an OEM part, it is designed to fit seamlessly into the engine s existing bushing housing. This simplifies the replacement process compared to aftermarket parts that might require additional tools or adjustments.

8. **Resale Value** If you plan to sell or trade in your bike later, having OEM parts installed can make the vehicle more appealing to buyers who prioritize original or high-quality components.

1. **Cost** NOS parts are significantly more expensive than aftermarket alternatives. The price reflects the brand reputation, quality, and direct sourcing from Kawasaki. For budget-conscious buyers, this can be a major drawback.

2. **Limited Availability** Finding NOS parts can be challenging, especially if the bike model is older or no longer in production. Prices may also fluctuate based on demand, making it harder to secure the part at a reasonable time.

3. **Potential for Overkill** If the bushing is only slightly worn or the failure is due to a minor issue (e.g., improper installation in the past), replacing it with a NOS part may be unnecessary. In such cases, an aftermarket part of comparable quality could suffice at a lower cost.

4. **Long Lead Times** Even if available, NOS parts may take weeks or months to arrive, especially if ordering from a distributor or overseas supplier. This can delay repairs or engine work.

5. **Risk of Counterfeit Parts** When purchasing from third-party sellers (e.g., eBay, Facebook Marketplace), there is a risk of receiving counterfeit or refurbished parts labeled as NOS. Always verify the seller s reputation and authenticity of the part.

6. **Installation Expertise Required** While the part itself is straightforward, improper installation (e.g., incorrect torque, misalignment, or contamination) can void its benefits and even cause damage. This requires mechanical skill or access to a professional.

7. **Environmental and Ethical Concerns** NOS parts are sourced from stockpiles, which may raise ethical questions about warehousing and disposal. Some buyers prefer supporting aftermarket manufacturers that produce parts sustainably.

8. **No Upgrades or Performance Gains** Unlike some aftermarket bushings designed for reduced friction or enhanced durability, a NOS part will not improve performance beyond the original specifications. If tuning or modifications are planned, aftermarket options might offer better compatibility.

### **Conclusion**

The Kawasaki 92028-1630 ZX-7R/ZX-7 crankshaft bushing (NOS) is a high-quality, reliable replacement that ensures proper engine function and longevity. It is ideal for riders who prioritize original equipment quality, long-term reliability, and the assurance of a direct fit. However, the higher cost, potential availability issues, and the need for careful installation must be weighed against the benefits.

For most serious riders or those restoring a classic bike, the investment in a NOS part is justified. However, if budget or urgency is a concern, a high-quality aftermarket bushing from a reputable manufacturer (e.g., JE, SC Motorworks, or DID) can offer comparable performance at a lower cost, provided the part meets OEM specifications.

---

### **Recommendation**

- You value original equipment quality and are willing to pay for it.

- You have access to a reliable seller (e.g., Kawasaki dealer, trusted online retailer).

- The part is critical to restoring the engine to factory specifications.

- You have the time and expertise to install it correctly.

- You are on a tight budget and can find a high-quality, OEM-compatible bushing.

- The part is only slightly worn, and a refurbished or aftermarket option would suffice.

- You need the part urgently and cannot wait for NOS delivery.

**Final Tip:** Always inspect the part upon arrival (if possible) and verify its authenticity. If purchasing from a third party, request a return policy or proof of authenticity (e.g., original packaging, invoice). For critical components like crankshaft bushings, err on the side of caution and prioritize quality over cost.
