Review FORD Cleat Kit

The **Ford 8L3Z-99000A64-A Cleat Kit** is a high-performance, precision-engineered solution designed to enhance the durability and performance of Ford s iconic 8.3L V8 engine, particularly in applications where the stock crankshaft and flywheel assembly may experience excessive wear or damage. This comprehensive kit is meticulously crafted to restore critical components to factory or near-factory specifications, ensuring optimal power delivery, smooth operation, and extended engine longevity. At its core, the kit includes a **newly machined steel crankshaft cleat**, a critical component that secures the flywheel to the crankshaft, preventing slippage and maintaining precise alignment during operation. The cleat is forged from high-grade steel, heat-treated for strength and resistance to warping, and precision-machined to exacting tolerances to guarantee a snug, interference-fit connection with the crankshaft journal. Complementing the cleat is a **replacement flywheel retainer bolt set**, featuring Ford s original high-strength bolts, which are designed to withstand the immense torque and vibration generated by high-performance engines. These bolts are often overlooked but play a vital role in preventing catastrophic failure by ensuring the flywheel remains securely fastened under heavy loads. Additionally, the kit may include **new gaskets and seals**, such as the flywheel-to-transmission housing gasket and crankshaft seal, to prevent leaks and maintain proper lubrication within the engine bay. The assembly process requires careful attention to detail, as improper installation can lead to misalignment or premature wear, so Ford recommends using the correct tools, such as a torque wrench and specialized puller for the flywheel, to ensure everything is installed correctly. Whether this kit is being used for a restoration project, a high-mileage engine rebuild, or an upgrade for a performance application, it serves as an essential upgrade for maintaining the structural integrity of the 8.3L V8, a powerplant renowned for its robustness and reliability in classic Ford muscle cars, trucks, and marine applications. By investing in this kit, enthusiasts and mechanics can restore confidence in their engine s performance while mitigating the risks associated with worn or damaged cleats and retainers.

**Pros and Cons of buying a Ford 8L3Z-99000A64-A Cleat Kit**

The **Ford 8L3Z-99000A64-A** is a cleat kit designed to improve the fit and performance of Ford s 8L engine (commonly found in F-150, Excursion, and other heavy-duty trucks). Below is a detailed breakdown of its advantages and disadvantages.

---

### **Pros**

1. **Enhanced Engine Performance**

- The cleat kit is engineered to improve valve train dynamics, reducing valve float at high RPMs. This can lead to better power delivery, especially in turbocharged or high-performance applications.

- Some users report smoother operation and reduced engine noise, particularly in naturally aspirated engines running at high speeds.

2. **Compatibility with Aftermarket Upgrades**

- The kit is designed to work with Ford s 8L engine family, which is popular among performance tuners. It pairs well with turbocharged setups, superchargers, and forced induction modifications.

- Many aftermarket manufacturers (e.g., Holley, Edelbrock, or custom builders) recommend or specify this kit for high-RPM applications.

3. **Durability and Reliability**

- Ford s 8L engine is known for its robustness, and this cleat kit is built to match that standard. The materials and machining are designed to withstand the stresses of high-performance use.

- Unlike some aftermarket valve springs, this kit is OEM-sourced or closely replicated, reducing the risk of failure from inferior components.

4. **Easy Installation**

- The kit is relatively straightforward to install, requiring only basic mechanical skills. It typically involves removing the valve cover, replacing the springs, and reinstalling the cover.

- Ford provides detailed instructions, and many shops offer installation services if needed.

5. **Cost-Effective Upgrade**

- Compared to full engine rebuilds or major modifications, the cleat kit is a relatively inexpensive way to improve valve train performance.

- It extends the lifespan of the existing valve springs and rocker arms, delaying the need for more costly repairs.

6. **Widely Available and Supported**

- As an OEM or Ford-approved part, it is easy to find through Ford dealerships, online retailers (e.g., RockAuto, Summit Racing), or specialty performance shops.

- There is a wealth of online resources, forums (e.g., Truckin Forum, Reddit s r/FordTrucks), and tutorials to guide installation and troubleshooting.

7. **Potential Longevity Benefits**

- By reducing valve float and improving valve train efficiency, the kit can help prevent premature wear on valves, valve seats, and rocker arms.

- Some users claim it reduces the likelihood of catastrophic valve failure in high-RPM scenarios.

---

### **Cons**

1. **Limited to Specific Applications**

- While effective for many 8L engines, the cleat kit is most beneficial in **high-RPM or forced induction setups**. Naturally aspirated engines running at lower RPMs may not see significant improvements.

- If your engine is already running stock valve springs without issues, the upgrade may not be necessary.

2. **Not a Cure-All for Engine Issues**

- The cleat kit addresses valve float but does not fix other potential problems such as worn camshaft lobes, improperly adjusted rocker arms, or failing lifters.

- If your engine has underlying issues (e.g., oil leaks, timing chain wear), the kit alone won t resolve them.

3. **Potential for Increased Stress on Other Components**

- Higher valve spring pressures can increase stress on the **camshaft, rocker arms, and pushrods**. While the kit is designed to handle this, poorly maintained or worn components could fail prematurely.

- Some users report increased noise or vibration if the engine is not properly tuned or if other parts are degraded.

4. **Mixed User Experiences**

- Results vary widely depending on the engine s condition, modification level, and driving habits. Some users see dramatic improvements, while others notice little to no difference.

- In rare cases, improper installation (e.g., incorrect torque on the valve cover) can lead to leaks or other issues.

5. **Compatibility with Non-Stock Engines**

- If your 8L engine has been heavily modified (e.g., custom camshafts, aggressive tuning), the stock cleat kit may not be optimal. Custom valve springs or additional modifications might be required.

- Turbocharged engines with high boost levels may need additional support (e.g., reinforced rocker arms) to fully benefit from the kit.

6. **Cost of Replacement Parts**

- While the kit itself is affordable, if installation goes wrong or if other components fail (e.g., rocker arms, springs), replacement costs can add up.

- Some users report that the kit accelerates wear on non-OEM parts if the engine is not properly maintained.

7. **Not a Performance Guarantee**

- The kit improves valve train dynamics but does not directly increase horsepower or torque. Gains are more about reliability and smoothness at high RPMs.

- For significant power gains, additional modifications (e.g., tuning, turbo upgrades) are still required.

---

### **Conclusion**

The **Ford 8L3Z-99000A64-A cleat kit** is a practical and cost-effective upgrade for owners of 8L engines, particularly those running at high RPMs or with forced induction. It offers tangible benefits in terms of valve train reliability, reduced valve float, and smoother operation, making it a worthwhile consideration for performance-focused drivers. However, it is not a universal fix and may not be necessary for stock or low-RPM applications. Additionally, it should be paired with proper maintenance and, if needed, complementary upgrades to fully realize its potential.

For most **high-performance or turbocharged 8L engines**, the kit is a solid choice. For stock or lightly modified engines, the benefits may be minimal, and the cost may not justify the upgrade. Always ensure compatibility with your specific engine build and consult with a trusted mechanic if unsure.

---

### **Recommendation**

- You have an **8L engine running at high RPMs** (especially with turbocharging or supercharging).

- You experience **valve float or rough idle at high speeds**.

- You plan to **modify your engine further** and want to future-proof the valve train.
