### **Pros and Cons of buying a Plus/Westar EM-4066 Engine Torque Strut Mount**

The **Plus/Westar EM-4066** is a torque strut mount designed to replace the stock torque strut assembly on certain Ford vehicles, particularly those with the **4.6L (Modular) or 5.4L (Trusted-Tec) engines** (e.g., F-150, Expedition, Navigator). Below is a detailed breakdown of its advantages and disadvantages.

---

### **Pros**

1. **Improved Durability and Strength**

The EM-4066 is constructed from **high-quality steel**, often thicker and more robust than the stock torque strut mount. This reduces the risk of **premature failure**, which is a common issue with OEM parts due to weak welds or thin material. Many users report that this mount lasts significantly longer than the factory unit, especially under heavy loads or towing conditions.

2. **Better Resistance to Vibration and Stress**

The stock torque strut mount is prone to **fatigue failure** over time, particularly in vehicles used for towing or off-roading. The EM-4066 is designed with **reinforced welds and a more rigid structure**, which helps absorb engine torque more effectively, reducing excessive movement and wear on related components (such as the engine mounts and transmission mounts).

3. **Easier Installation**

Unlike some aftermarket torque strut mounts that require extensive modifications, the **EM-4066 is designed to be a direct replacement** for the stock unit. It typically fits without requiring additional drilling or welding, making it a **plumber s drop-in solution** for those who want a simple upgrade without major fabrication.

4. **Compatibility with Aftermarket Upgrades**

Many users install the EM-4066 as part of a **torque strut mount kit** (often paired with upgraded engine mounts or transmission mounts). This makes it a **versatile choice** for those looking to improve driveline rigidity, reduce engine movement, and enhance overall drivability, especially in performance or towing applications.

5. **Positive User Feedback and Reputation**

Plus/Westar is a well-regarded brand in the aftermarket performance and towing community. The **EM-4066 has received favorable reviews** for its **reliability, ease of installation, and effectiveness** in reducing engine bounce and driveline stress. Many forums (e.g., Ford Truck Forum, Truckin 101) feature success stories from users who have seen noticeable improvements in their vehicle s handling and longevity after installing this part.

6. **Cost-Effective Upgrade**

Compared to **full torque strut mount kits** or custom fabrication, the EM-4066 is **relatively affordable**. It provides a **significant upgrade over the stock part** without the high cost of premium brands like **Mega-Mounts or Heavy-Duty Torque Strut Mounts**. For many, it offers the best balance of **performance and value**.

7. **Reduces Engine and Transmission Wear**

By minimizing excessive movement in the driveline, the EM-4066 helps **prevent premature wear** on the **engine mounts, transmission mounts, and even the engine itself**. This can lead to **longer component life** and fewer costly repairs over time.

8. **Works Well with Stock and Modified Engines**

Whether the vehicle is running a **stock 4.6L or a modified engine (e.g., supercharged, turbocharged, or high-torque builds)**, the EM-4066 provides **enhanced support**. It is particularly beneficial for **high-horsepower applications** where the stock mount would likely fail under stress.

---

### **Cons**

1. **Not a Complete Driveline Solution**

While the EM-4066 is an **excellent torque strut mount**, it is **not a full torque strut mount kit**. If you install it alone, you may still experience **excessive engine movement** unless you also upgrade the **engine mounts or transmission mounts**. Some users report that pairing it with **stock mounts can lead to uneven stress distribution**, potentially causing issues elsewhere in the driveline.

2. **Requires Proper Installation**

Like any mechanical upgrade, the **EM-4066 must be installed correctly** to avoid voiding its benefits. Improper alignment, loose bolts, or incorrect torque settings can **negate its advantages** and may even cause **new problems** (e.g., binding, excessive strain on other mounts). Users should follow **manufacturer guidelines** or consult a professional if unsure.

3. **Limited Customization**

The EM-4066 is a **standardized replacement part** and does not offer **adjustable or modular features** like some high-end torque strut mount kits. If a vehicle has **unique driveline dynamics** (e.g., extreme angles or custom builds), the stock fit may not be perfect, requiring additional modifications.

4. **Weight Consideration**

While the EM-4066 is **heavier than the stock mount**, this is generally a **positive** (as it improves rigidity). However, in **lightweight or high-performance applications**, some users may prefer **lighter aftermarket options** for tuning purposes. That said, the weight difference is minimal compared to the benefits.

5. **Potential for Over-Tightening**

Because the EM-4066 is so strong, **over-tightening the bolts** can lead to **warping or stress cracks** in the mount or surrounding components. Users must follow **torque specifications** carefully to avoid damaging the part or the vehicle s frame.

6. **Not a Substitute for Full Driveline Upgrades**

If a vehicle has **worn or failing engine mounts, transmission mounts, or sway bar links**, installing just the EM-4066 will **not fully resolve driveline issues**. A **comprehensive torque strut mount kit** (including all related components) may be necessary for optimal results.

7. **Availability and Fitment Variations**

While the EM-4066 is widely compatible with **Ford 4.6L/5.4L vehicles**, there may be **slight variations in fitment** depending on the **model year, trim, or driveline configuration** (e.g., 4x4 vs. 2WD). Some users report needing to **file or adjust** the mount slightly for a perfect fit. Always **verify fitment** before purchasing.

8. **No Warranty on Installation Issues**

Plus/Westar typically offers a **limited warranty on the part itself**, but **installation errors are not covered**. If a user damages the mount (or the vehicle) during installation, they are responsible for repairs.

---

### **Ending Conclusion**

The **Plus/Westar EM-4066 Engine Torque Strut Mount** is a **highly effective and reliable upgrade** for Ford vehicles with the **4.6L or 5.4L engine**, particularly those used for **towing, hauling, or performance applications**. Its **superior durability, ease of installation, and positive user feedback** make it one of the best **budget-friendly torque strut mounts** available.

However, it is **not a standalone solution** for best results, it should be paired with **compatible engine and transmission mounts** to ensure balanced driveline support. Proper installation is **critical**, and users should not expect it to **completely eliminate engine movement** without additional upgrades.

If your primary goal is to **extend the life of your torque strut mount, reduce driveline stress, and improve overall rigidity**, the EM-4066 is an **excellent choice**. For **extreme applications** (e.g., heavy-duty towing, high-horsepower builds, or custom fabrications), a **full torque strut mount kit** may be more appropriate.

---

### **Final Recommendation**

**Buy the Plus/Westar EM-4066 if:**
