Review ENGINETECH Crankshaft Kit Main And Connecting Rod Bearings Direct Fit

The **Enginetech 138600 Crankshaft Kit with Connecting Rod Bearings** represents a premium, high-performance upgrade designed for enthusiasts and professionals seeking to restore or enhance the durability, efficiency, and power output of their engine. Engineered with precision and built to exacting standards, this kit is meticulously crafted to deliver seamless operation and extended longevity, making it an ideal choice for both classic and modern high-performance applications. The crankshaft in this kit is forged from high-grade alloy steel, ensuring superior strength, resistance to fatigue, and the ability to withstand the intense stresses of high-revving engines without compromising structural integrity. Its polished surfaces and finely balanced design minimize friction, allowing for smoother operation and reduced wear on associated components, such as the rod bearings and main journals. The connecting rod bearings included in this kit are constructed from high-quality, oil-impregnated bronze or composite materials, depending on the specific application, providing exceptional load-bearing capacity and thermal stability. These bearings are designed to maintain a consistent oil film under extreme conditions, preventing metal-to-metal contact and reducing the risk of catastrophic failure. The kit is compatible with a wide range of engine displacements and configurations, including but not limited to inline-four, inline-six, and V8 applications, making it a versatile solution for a diverse array of automotive and performance tuning scenarios. Whether you are restoring a vintage engine to its former glory or pushing a modern performance engine to its limits, this crankshaft kit offers the reliability and performance necessary to meet demanding requirements. Enginetech s commitment to quality ensures that every component is rigorously inspected and tested to guarantee a perfect fit and optimal performance, allowing you to focus on achieving your engine s full potential without the worry of premature wear or failure.

**Pros and Cons of buying a EngineTech 138600 Crankshaft Kit with Connecting Rod Bearings**

The EngineTech 138600 crankshaft kit, which includes connecting rod bearings, is a popular choice among performance and restoration enthusiasts for several reasons:

1. **High-Quality Materials** EngineTech products are known for using premium materials, including high-grade steel and advanced coatings, which enhance durability and resistance to wear. The crankshaft is precision-machined to tight tolerances, ensuring smooth operation and longevity.

2. **Performance Enhancements** This kit is designed for high-performance applications, including forced induction (turbocharged or supercharged) engines. The upgraded crankshaft and bearings can improve power output, reduce friction, and increase engine reliability under heavy loads.

3. **Compatibility** EngineTech offers kits for a wide range of engine displacements and applications, including popular V8 and inline engines. The 138600 kit is specifically designed for certain GM small-block and big-block applications, ensuring a proper fit without modifications.

4. **Warranty and Support** EngineTech provides a solid warranty (typically 12 months or more) and reliable customer support. This gives buyers confidence in the product s quality and reduces the risk of premature failure.

5. **Ease of Installation** The kit is designed with installation in mind, often including detailed instructions and sometimes even gasket sets or other necessary components. This can simplify the rebuild process for DIYers.

6. **Aftermarket Reputation** EngineTech is a well-established brand with a strong reputation in the aftermarket for producing reliable, high-performance parts. Many mechanics and enthusiasts trust their products for critical engine components.

7. **Balanced Weight** The crankshaft is often dynamically balanced, which helps reduce vibration and improve engine smoothness, especially at high RPMs.

---

1. **Cost** High-performance crankshaft kits are not cheap. The EngineTech 138600 kit, depending on the specific application and additional components included, can be significantly more expensive than OEM or basic aftermarket alternatives. This may be a barrier for budget-conscious builders.

2. **Specialized Applications** While EngineTech covers many popular engines, not all applications may have a direct-fit kit. Some builds may require additional machining or custom work, increasing labor costs and complexity.

3. **Installation Expertise Required** Replacing a crankshaft and bearings is a labor-intensive process that requires mechanical skill. Mistakes during installation (e.g., improper bearing alignment, incorrect torque specs, or contamination) can lead to catastrophic engine failure. Professional installation is often recommended.

4. **Potential for Overkill** If the engine is not being heavily modified or stressed (e.g., stock or lightly modified daily drivers), the benefits of a high-performance crankshaft kit may not be fully realized. In such cases, a standard OEM or lightly upgraded kit might suffice.

5. **Compatibility with Other Components** Upgrading the crankshaft may require complementary upgrades, such as stronger rods, pistons, or a reinforced block, to fully leverage the kit s potential. Failure to address these can limit performance or lead to premature wear.

6. **Lead Time** Like many high-performance parts, EngineTech kits may have longer lead times due to custom manufacturing. Buyers should plan accordingly, especially if they are on a tight timeline.

7. **Resale Value Impact** While not a con for most enthusiasts, heavily modified engines with aftermarket crankshafts may have lower resale value compared to stock or lightly modified engines, depending on the market.

The EngineTech 138600 crankshaft kit with connecting rod bearings is an excellent choice for enthusiasts and builders who prioritize performance, reliability, and durability in their engines. It is particularly well-suited for forced induction applications, high-RPM use, or engines that will be subjected to heavy loads. The kit s high-quality materials, precision engineering, and strong aftermarket reputation make it a trusted option for those willing to invest in a long-term, high-performance solution.

However, the kit is not without drawbacks. The cost, specialized nature, and complexity of installation mean it is best suited for experienced builders or those working with a trusted mechanic. It may also be overkill for stock or lightly modified engines where simpler, more affordable alternatives could suffice.

---

- You are building or modifying an engine for high-performance use, such as forced induction, racing, or heavy-duty applications.

- You have the budget to invest in a premium, long-lasting solution.

- You are comfortable with or have access to professional installation services to ensure proper fitment and assembly.

- Your engine s application aligns closely with EngineTech s supported configurations (verify compatibility with your specific engine displacement and application).

- You value the brand s reputation for quality and reliability, and are willing to accept the higher upfront cost for potential long-term benefits.

- Your engine is a stock or lightly modified daily driver where the benefits of a high-performance crankshaft are not necessary.

- You are working with a tight budget and could achieve similar results with a more affordable OEM or mid-range aftermarket kit.

- You lack experience with engine rebuilds and are not confident in handling the installation yourself.

- Your engine s application does not have a direct-fit EngineTech kit, requiring additional custom work or compromises.

- You prioritize resale value or plan to return the vehicle to stock-like condition in the future.

For most performance-focused builds especially those involving forced induction or aggressive modifications the EngineTech 138600 kit is a strong recommendation. Just ensure you pair it with the rest of the engine s components (rods, pistons, block reinforcement, etc.) to fully realize its potential. Always consult with a trusted mechanic or engine builder to confirm compatibility and installation best practices.
