Review GMC Replacement Front Engine Mount Set Hd 6.6l V8 fits SIERRA 3500 2011–2016

The **45PZRQ Front Engine Mount Set** is a premium, high-performance replacement part designed specifically for the **2011 2016 GMC Sierra 3500 HD** equipped with the **6.6L Duramax V8 diesel engine**. Engine mounts are critical components that isolate the engine from the vehicle s chassis, absorbing vibrations, reducing noise, and ensuring smooth operation while maintaining proper alignment. This set features **heavy-duty construction** with **reinforced rubber and steel components**, engineered to withstand the demanding stresses of heavy-duty towing, hauling, and off-road use. The mounts are precision-molded to match the original equipment manufacturer (OEM) specifications, ensuring a perfect fit without compromising performance or durability. Whether you re a fleet operator, a professional trucker, or an enthusiast who demands reliability, this mount set delivers **superior vibration dampening**, **enhanced engine stability**, and **long-lasting performance** critical for maintaining optimal engine function and preventing premature wear on related components. Built to meet or exceed factory standards, these mounts are an essential upgrade for anyone looking to extend the lifespan of their Duramax engine while minimizing fatigue and operational noise.

### **Pros and Cons of buying a 45PZRQ Front Engine Mount Set for a 2011-2016 GMC Sierra 3500 (6.6L V8)**

1. **Improved Engine Mount Durability** The stock engine mounts on a 6.6L Duramax diesel are known to wear out over time, leading to excessive vibration, rattling, and potential engine damage. Replacing them with an aftermarket set like the 45PZRQ can restore stability and reduce wear on surrounding components.

2. **Reduced Vibration and Noise** Worn mounts allow the engine to shift, causing increased vibration that can be felt through the steering wheel, floorboards, and cabin. New mounts help dampen these vibrations, leading to a quieter and smoother ride.

3. **Prevents Further Damage** If the mounts fail completely, the engine can move excessively, damaging the transmission, exhaust system, or even the firewall. Replacing them proactively can avoid costly repairs down the line.

4. **Better Fit and Compatibility** The 45PZRQ set is specifically designed for the 2011-2016 GMC Sierra 3500 with the 6.6L V8, ensuring a proper fit without modifications. This reduces the risk of installation issues compared to generic mounts.

5. **Long-Term Reliability** High-quality rubber mounts (assuming the 45PZRQ set is well-made) will last significantly longer than OEM parts, which often fail prematurely due to heat and stress.

6. **Potential Improvement in Drivability** A properly mounted engine can reduce harshness during acceleration and deceleration, leading to a more refined driving experience.

7. **Warranty Coverage** Many reputable aftermarket brands offer warranties on their mounts, providing peace of mind in case of early failure.

---

1. **Cost** While not excessively expensive, the price of a quality engine mount set (typically $100 $200) adds up when combined with labor costs (if not doing it yourself). For a DIYer, the parts alone may be the main expense.

2. **Installation Difficulty** Replacing engine mounts requires lifting the vehicle, disconnecting the battery, and potentially removing the radiator or other components for better access. This can be time-consuming and physically demanding, especially for those without mechanical experience.

3. **Potential for Counterfeit Parts** Some aftermarket mounts sold under similar part numbers may be low-quality or counterfeit. Buying from a trusted supplier (e.g., RockAuto, Summit Racing, or a local diesel specialty shop) helps mitigate this risk.

4. **Limited Lifespan Compared to Other Components** While better than OEM, engine mounts still degrade over time due to heat, vibration, and age. They may need replacement again in 5 10 years, depending on driving conditions.

5. **Possible Additional Work Needed** If the mounts are extremely worn, the surrounding areas (like the engine cradle or firewall) may also need inspection or repair, adding to the cost.

6. **Not a Permanent Fix for All Issues** If the problem stems from something else (e.g., a failing transmission mount, exhaust hangers, or a damaged subframe), replacing just the front engine mounts may not fully resolve vibration or noise issues.

The **45PZRQ front engine mount set is a worthwhile upgrade for a 2011-2016 GMC Sierra 3500 with a 6.6L V8**, especially if the stock mounts are worn or failing. The benefits reduced vibration, improved stability, and prevention of further damage outweigh the drawbacks for most owners. However, the installation process is labor-intensive, and the parts must be sourced from a reliable supplier to ensure quality.

If you re experiencing noticeable engine movement, rattling, or excessive vibration, replacing the mounts is a **cost-effective preventive measure** that can extend the life of your engine and transmission. For those comfortable with basic mechanical work, it s a manageable DIY project. If not, factoring in labor costs is still a reasonable investment compared to potential future damage.

- **Buy from a trusted source** (e.g., RockAuto, Summit Racing, or a local diesel shop) to avoid counterfeit or low-quality parts.

- **Inspect the mounts before purchasing** if they re already cracked or degraded, replacement is urgent.

- **Consider a full engine support system upgrade** (e.g., replacing all three mounts or adding a transmission mount) if you re doing the work, as it provides better long-term stability.

- **Follow proper installation procedures**, including torque specifications and alignment, to ensure the new mounts function correctly.

- **Monitor for any lingering issues** after installation if vibration persists, check other components like exhaust hangers or subframe bushings.

**Final Verdict:** **Highly recommended** for owners experiencing engine mount wear, as it s a straightforward and effective solution to prevent further damage and improve drivability.
