**Pros and Cons of buying a Zidus 90738S Engine Timing Chain Kit (VVT Cam Phaser) for Ford F-150 (2.7L EcoBoost or 3.5L V6) / Taurus (3.5L V6)**
### **Pros:**1. **Compatibility and Fitment** The Zidus 90738S is specifically designed for Ford s 3.5L V6 (Forth) and 2.7L EcoBoost (Duratec) engines, including applications like the F-150 and Taurus. It includes the timing chain, sprockets, tensioner, and VVT cam phaser, ensuring all critical components are replaced at once.
2. **High-Quality Materials** Zidus uses durable materials, including hardened sprockets and a precision-machined tensioner, which helps prevent premature wear and chain stretch. The cam phaser is designed to maintain proper valve timing for optimal engine performance.
3. **Complete Replacement Kit** Unlike aftermarket chains sold separately, this kit includes everything needed for a full timing chain service, reducing the chance of forgetting parts or needing additional purchases.
4. **OEM-Level Performance** The components are engineered to match or exceed OEM specifications, helping restore proper engine timing, reduce noise, and prevent catastrophic failure (e.g., bent valves or rod damage).
5. **Ease of Installation** The kit comes with clear instructions, and since it s a direct replacement, it should fit without extensive modifications. Many users report that it installs similarly to OEM parts, though some may require basic tools and patience.
6. **Cost-Effective Alternative to OEM** Compared to buying individual OEM parts, this kit is often more affordable while still providing reliable performance.
7. **Reduces Engine Noise and Vibration** A worn timing chain can cause rattling or ticking noises. Replacing it with this kit can eliminate those symptoms, improving drivability.
8. **Prevents Future Failures** Timing chains stretch or wear over time, leading to improper valve timing, reduced power, or complete failure. Replacing it proactively extends the engine s lifespan.

### **Cons:**1. **Potential for Counterfeit Concerns** Some Zidus products have faced allegations of being counterfeit or of lower quality than advertised. Buyers should verify the seller s authenticity (e.g., purchasing from a reputable auto parts dealer or Amazon with positive reviews).
2. **Installation Complexity** While not extremely difficult, replacing a timing chain requires careful attention to alignment, tensioner adjustment, and phaser calibration. Improper installation can lead to premature failure or engine damage. Some users may need to consult a manual or seek professional help.
3. **Limited Warranty** Zidus typically offers a limited warranty (e.g., 1 2 years), which may not cover all potential issues, especially if installation is improper. OEM parts often come with longer warranties.
4. **Mixed Reviews on Durability** Some users report that while the Zidus kit works well initially, it may not last as long as OEM parts, especially in high-mileage or performance applications. Others have no issues and find it reliable.
5. **May Not Include Additional Needed Parts** Depending on the engine s condition, additional components (e.g., water pump, tensioner seals, or guides) may need replacement. The kit itself does not always include these, requiring extra purchases.
6. **Potential for Chain Stretch Over Time** Even high-quality aftermarket chains can stretch with high mileage or aggressive driving. Some users report needing to replace it again sooner than expected.
7. **Not a "Lifetime" Solution** Unlike some OEM chains in older engines, modern Ford chains (especially in EcoBoost engines) are designed for longevity but still require eventual replacement. This kit is not a permanent fix.
