---

### **Pros of Buying Mitsubishi MD117083 Connecting Rod Bolts**

1. **Original Equipment Manufacturer (OEM) Quality**

The bolts from Mitsubishi are designed and manufactured to meet the exact specifications of the engine. This ensures a precise fit, reducing the risk of misalignment or improper tensioning, which can lead to catastrophic engine failure. OEM parts are typically forged from high-strength materials, such as alloy steel, and undergo rigorous heat treatment to achieve the required tensile strength and durability.

2. **Reliability and Performance**

Connecting rod bolts are subjected to extreme stress, including high compression forces, vibrations, and thermal cycling. OEM bolts are engineered to withstand these conditions, providing consistent performance and longevity. Using genuine parts minimizes the risk of premature bolt failure, which could result in a rod breaking and causing severe engine damage.

3. **Compatibility and Fit**

Aftermarket or non-OEM bolts may not match the exact dimensions, thread pitch, or material properties of the original bolts. This can lead to issues such as improper tightening, galling (metal-to-metal wear), or even bolt stripping. Mitsubishi bolts are guaranteed to fit perfectly, reducing the likelihood of installation errors.

4. **Warranty and Support**

Purchasing OEM bolts often comes with the benefit of Mitsubishi s warranty coverage, depending on the retailer or distributor. This provides peace of mind, especially if the bolts are part of a larger engine rebuild or replacement. Additionally, Mitsubishi offers technical support and documentation to ensure proper installation and maintenance procedures are followed.

5. **Long-Term Cost Savings**

While OEM bolts may be more expensive upfront than aftermarket alternatives, they are less likely to fail prematurely. Frequent bolt failures can lead to costly repairs, downtime, and potential safety hazards. Investing in quality bolts upfront can save money in the long run by avoiding repeated replacements or catastrophic engine damage.

6. **Safety**

The connecting rod assembly is one of the most critical components in an internal combustion engine. A failure here can result in a rod striking the cylinder walls, pistons, or crankshaft, causing extensive damage. Using high-quality, properly torqued bolts significantly reduces the risk of such failures, enhancing the overall safety of the engine.

7. **Ease of Availability**

Mitsubishi bolts are widely available through authorized dealers, marine supply stores, and online retailers. This ensures that you can easily obtain replacements when needed, without relying on hard-to-find or counterfeit parts.

### **Cons of Buying Mitsubishi MD117083 Connecting Rod Bolts**

1. **Higher Cost**

The primary drawback of purchasing OEM bolts is their higher price compared to aftermarket or generic alternatives. For budget-conscious buyers, this can be a significant factor, especially if multiple bolts are required or if the engine is part of a larger project with limited funds.

2. **Potential for Overkill**

In some cases, aftermarket bolts may meet or exceed the specifications of OEM bolts, particularly if they are manufactured by reputable suppliers (e.g., ARP, Fel-Pro, or other high-quality aftermarket brands). For applications where the engine operates under less severe conditions, OEM bolts may be more expensive than necessary.

3. **Limited Customization**

OEM bolts are standardized to fit the engine s design and are not customizable. If you require specialized features (e.g., different thread coatings, unique head designs, or custom torque specifications), you may need to explore aftermarket options that offer more flexibility.

4. **Lead Time for Orders**

Depending on the retailer or distributor, there may be delays in receiving OEM parts, particularly if the bolts are not stocked locally. This can cause inconvenience, especially in time-sensitive projects or emergency repairs.

5. **Misuse or Improper Installation Risks**

Even with OEM bolts, improper installation such as overtightening, undertightening, or incorrect torque sequencing can lead to failure. While Mitsubishi provides guidelines, human error during installation remains a risk. This underscores the importance of following proper procedures, regardless of the bolt s origin.

6. **Environmental and Ethical Considerations**

Some buyers may prefer to avoid OEM parts due to environmental concerns (e.g., mining for metals, manufacturing processes) or ethical considerations (e.g., labor practices in manufacturing). While this is subjective, it is worth noting as a potential factor for some consumers.

### **Conclusion**

The decision to purchase Mitsubishi MD117083 connecting rod bolts should prioritize the critical nature of these components in engine performance and safety. The benefits of using OEM bolts such as reliability, precision fit, warranty support, and long-term cost savings far outweigh the drawbacks for most applications. While the higher cost may be a consideration, the potential consequences of using inferior bolts (e.g., engine failure, safety hazards, or costly repairs) make OEM parts the safest and most prudent choice for serious engine owners, marine operators, or industrial users.

For less demanding applications or budget constraints, high-quality aftermarket bolts from trusted manufacturers (e.g., ARP, Torq-Sek, or Fel-Pro) may offer a viable alternative, provided they meet or exceed the original specifications. However, without thorough research and verification, aftermarket bolts carry a higher risk of failure and should not be assumed to be equivalent to OEM parts.

---

### **Recommendation**

For the Mitsubishi MD117083 engine, **purchase genuine Mitsubishi connecting rod bolts** when available. Here s why:

- **Prioritize safety and reliability**: The connecting rod assembly is a high-stress component, and using OEM bolts minimizes the risk of failure.

- **Follow torque specifications**: Always use a torque wrench and adhere to Mitsubishi s recommended tightening sequence and specifications (typically around 120-140 ft-lbs for these bolts, but verify the exact value in the engine manual).

- **Consider professional installation**: If you are not experienced with engine disassembly and reassembly, consult a certified mechanic to ensure proper installation.

- **Store bolts properly**: Keep bolts in a dry, clean environment to prevent corrosion or damage before installation.

- **Documentation**: Retain the engine manual or service bulletins for future reference, as specifications may vary slightly between engine models or years.

If you are working within a tight budget and cannot afford OEM bolts, **opt for a reputable aftermarket brand** that specializes in high-performance engine components. Brands like ARP (Advanced Racing Products) or Torq-Sek are known for their quality and often provide superior strength and coatings compared to OEM bolts. However, always verify that the aftermarket bolts meet or exceed the original specifications and consult with an expert before installation.

Ultimately, the cost of a few bolts pales in comparison to the potential cost of engine damage or injury caused by a bolt failure. Investing in quality upfront is the most responsible approach.
