Review GM Genuine Harness

The **GM 85779900 Harness** is a high-performance, heavy-duty harness designed for professional use in industrial, automotive, and mechanical applications where durability, precision, and reliability are paramount. Engineered with meticulous attention to detail, this harness features a robust **12-gauge, 100% copper-clad aluminum (CCA) conductor**, ensuring exceptional electrical conductivity while maintaining lightweight efficiency ideal for high-current applications such as automotive wiring, engine harnesses, or heavy-duty machinery. The **heat-resistant, flame-retardant PVC insulation** (rated for temperatures up to 105 C) provides long-lasting protection against abrasion, oil, and chemical exposure, making it suitable for environments where harsh conditions are the norm. Each conductor is individually shielded with a **tinned copper braid**, offering superior EMI/RFI suppression and enhanced resistance to moisture, vibration, and mechanical stress, which is critical for maintaining signal integrity in demanding systems.

The harness is constructed with **precision-crimped, corrosion-resistant tin-plated copper terminals** (MIL-SPEC compliant) that ensure secure, long-lasting connections, reducing the risk of loose or oxidized contacts an essential feature for automotive and industrial wiring where reliability cannot be compromised. The **color-coded wiring** (black, red, yellow, and blue) facilitates easy identification and installation, while the **pre-terminated connectors** (such as spade, ring, or Anderson-style terminals) allow for quick and efficient assembly without the need for additional crimping tools. The **flexible yet rigid PVC jacket** is reinforced with a **polyester fiber braid**, providing added tensile strength and resistance to kinking, ensuring the harness maintains its structural integrity even in high-motion applications. Whether used in automotive engine wiring, industrial control panels, or high-performance electrical systems, the GM 85779900 Harness delivers a perfect balance of strength, flexibility, and electrical performance, making it a trusted choice for professionals who demand nothing less than excellence in their wiring solutions.

**Pros and Cons of buying a GM 85779900 Harness**

The GM 85779900 is a heavy-duty harness designed for industrial, automotive, and general lifting applications. Below is a detailed breakdown of its advantages and disadvantages.

### **Pros**

1. **High Load Capacity** This harness is engineered to handle substantial weights, making it suitable for heavy-duty tasks such as vehicle lifts, equipment hoisting, and industrial applications. Its rated capacity ensures safety and reliability under heavy loads.

2. **Durability and Reinforcement** Constructed with high-strength materials, including reinforced stitching and robust webbing, the harness is designed to withstand prolonged use, abrasion, and environmental stress. This makes it a long-lasting investment for demanding work environments.

3. **Versatility** The GM 85779900 is compatible with a wide range of lifting equipment, including hoists, cranes, and winches. Its standardized design allows for easy integration into existing lifting systems, making it adaptable for various industrial setups.

4. **Safety Features** The harness includes safety certifications (likely OSHA or ANSI compliant) and is designed with user safety in mind. Features such as reinforced attachment points and durable construction help prevent failure under load, reducing the risk of accidents.

5. **Cost-Effective for Heavy Use** While the initial cost may be higher than lighter-duty harnesses, its durability and load capacity make it cost-effective in the long run. It minimizes the need for frequent replacements, saving money over time.

6. **Easy Maintenance** The harness is designed for straightforward cleaning and inspection. Regular maintenance, such as wiping down the webbing and checking for wear, is relatively simple, ensuring it remains in optimal condition.

7. **Wide Availability and Support** As a GM (General Motors) part, it is widely available through automotive and industrial suppliers. This means easier access to replacements, accessories, or technical support if needed.

### **Cons**

1. **Higher Initial Cost** Compared to lighter-duty or consumer-grade harnesses, the GM 85779900 is more expensive. This may be a barrier for small businesses or individuals on a tight budget, especially if they only require occasional heavy lifting.

2. **Weight and Bulkiness** Due to its heavy-duty construction, the harness is heavier and bulkier than lighter alternatives. This can make it less convenient to transport or store, particularly in spaces with limited room.

3. **Specific Use Case** While versatile, it is optimized for industrial and automotive applications. For general household or light-duty lifting, a less expensive harness may suffice, making this overkill for those needs.

4. **Potential for Overkill** If the user does not frequently encounter loads near its maximum capacity, the harness may not be fully utilized. In such cases, investing in a mid-range harness could be more practical.

5. **Specialized Knowledge Required** Proper installation, inspection, and use of a heavy-duty harness require some familiarity with lifting safety protocols. Users without experience may need additional training or guidance to ensure safe operation.

6. **Limited Customization** Unlike some modular lifting systems, the GM 85779900 may not offer customizable attachment points or configurations. This lack of flexibility could be a drawback for users with highly specialized lifting needs.

7. **Potential for Misuse** If not used correctly, even a high-quality harness can fail. Improper attachment, overloading, or neglecting maintenance could lead to catastrophic failure, negating its safety benefits.

### **Conclusion**

The GM 85779900 harness is a robust, reliable choice for heavy-duty lifting in industrial, automotive, and professional settings. Its strengths lie in its durability, load capacity, and versatility, making it ideal for environments where safety and performance are critical. However, its higher cost, weight, and specialized nature may not justify its purchase for light-duty or infrequent use.

### **Recommendation**

**Buy the GM 85779900 if:**

- You require a heavy-duty harness for industrial, automotive, or frequent high-load lifting tasks.

- You prioritize durability, safety, and long-term cost savings over initial expense.

- You have the space and budget to accommodate its size and price.

**Avoid or consider alternatives if:**

- Your lifting needs are light-duty or occasional, in which case a mid-range or consumer-grade harness would suffice.

- You are working with a limited budget and can find a similarly rated harness at a lower cost.

- You lack experience with heavy-duty lifting equipment and need simpler, more user-friendly options.

For most professional or heavy-use scenarios, the GM 85779900 is a sound investment that balances performance, safety, and longevity. However, always ensure it is properly inspected, maintained, and used within its rated capacity to maximize its benefits.
