Review MOPAR New Old Stock Connecting Rod Bearing Pair Cyl Model's #1238568

The **Mopar 1238568 Connecting Rod Bearing** is a precision-engineered, high-performance aftermarket bearing designed to deliver exceptional durability, reliability, and performance in modern high-output and performance-oriented engines, particularly those built for Mopar applications. Crafted from a proprietary blend of high-grade, lead-free, and tin-based alloys, this bearing is engineered to withstand the extreme stresses of forced induction, turbocharging, and high-revving applications while maintaining optimal lubrication and load-bearing capacity. The bearing features a **split-shell design**, allowing for easy installation and removal without the need for specialized tools, making it ideal for both professional mechanics and dedicated DIY enthusiasts working on high-performance engines such as the **Hemi, Magnum, or EcoBoost** platforms. Its **oil groove and oil hole alignment** ensures consistent lubrication under heavy loads, reducing friction and minimizing the risk of catastrophic failure, even in demanding conditions where oil flow may be compromised.

Constructed with **thin-wall technology**, the Mopar 1238568 bearing offers superior conformability, allowing it to adapt to minor surface irregularities in the crankshaft journals while maintaining a secure, stable fit. This adaptability enhances engine longevity by preventing premature wear on both the bearing and crankshaft, making it a preferred choice for builders pushing the limits of power output. The bearing s **high-temperature stability** ensures consistent performance across a wide operational range, from cold starts to sustained high-RPM operation, making it well-suited for engines running on premium fuels, ethanol blends, or even nitrous oxide setups. Additionally, its **corrosion-resistant coating** provides protection against moisture and contaminants, extending service life in environments where engines may be exposed to harsh conditions or stored for extended periods.

For applications requiring maximum strength and endurance, the Mopar 1238568 bearing is often specified in **high-performance street rods, drag racing engines, and professional racing applications**, where reliability is paramount. Its compatibility with a wide range of **Mopar engine families**, including the **3.6L Pentastar, 5.7L Hemi, and 6.4L Hemi**, ensures broad applicability across both stock and heavily modified powerplants. Whether used in a **restomod project, a high-mileage daily driver, or a competition-grade engine**, this bearing delivers the precision and performance expected from Mopar s legacy of engineering excellence. When paired with high-quality oils and proper installation techniques, the Mopar 1238568 connecting rod bearing sets a new standard for dependability, making it an indispensable component for anyone seeking to maximize engine life and performance.

### Pros and Cons of buying a Mopar 1238568 Connecting Rod Bearing

1. **OEM Quality** Mopar is a trusted brand under the Chrysler/Dodge brand, known for producing genuine parts that meet factory specifications. This ensures compatibility and reliability with your engine.

2. **Direct Fitment** The part is designed specifically for certain Mopar engines (such as the 318, 360, or 440 series, depending on the application), reducing the risk of sizing issues or clearance problems.

3. **Durability** High-quality bearings are engineered to withstand high stress, heat, and pressure, extending the lifespan of your engine if installed correctly.

4. **Warranty Coverage** Mopar parts often come with a warranty (typically 12 24 months), providing peace of mind against premature failure.

5. **Ease of Installation** Since it s an OEM part, it should fit seamlessly with existing engine components, reducing the need for modifications or additional tools.

6. **Performance Consistency** Unlike aftermarket bearings that may vary in quality, Mopar ensures consistent performance across all units.

7. **Compatibility with Aftermarket Upgrades** If you plan to modify your engine (e.g., forced induction, high RPM), OEM bearings provide a solid foundation before considering premium aftermarket options.

1. **Higher Cost** Compared to aftermarket or generic bearings, Mopar parts are typically more expensive, which may be a drawback for budget-conscious buyers.

2. **Limited Availability** Depending on the specific engine model, finding the exact part number (1238568) may require ordering from an authorized dealer or online retailer, potentially adding shipping time.

3. **Overkill for Stock Engines** If your engine runs stock (no forced induction, high-performance tuning, or extreme loads), a premium OEM bearing may not offer significant advantages over a high-quality aftermarket alternative.

4. **Potential for Over-Engineering** Some aftermarket bearings are designed for specific applications (e.g., high-performance or marine use) and may outperform OEM bearings in those scenarios.

5. **Installation Complexity** While straightforward, replacing connecting rod bearings requires precision (proper gap measurement, correct torque specs, and alignment). Mistakes can lead to engine damage.

### **Conclusion**

The Mopar 1238568 connecting rod bearing is an excellent choice if you prioritize **reliability, OEM fitment, and warranty coverage**, especially for high-mileage or performance-oriented engines. It s ideal for those who want to avoid compatibility issues or prefer sticking with factory-spec parts. However, if cost is a concern or your engine runs stock with no aggressive modifications, a **high-quality aftermarket bearing** (e.g., from Clevite, Fel-Pro, or Scat) may offer a comparable lifespan at a lower price.

For **stock or lightly modified engines**, aftermarket bearings are often sufficient. For **high-performance, turbocharged, or heavily modified engines**, the Mopar bearing provides a solid, trustworthy option but you may still want to consider **premium aftermarket bearings** (e.g., Scat X777 or Clevite 262) for extreme applications.

---

### **Recommendation**

- You need a **direct OEM replacement** for a specific engine application.

- You want **maximum reliability** and **warranty protection**.

- Your engine is **high-performance or heavily modified** (e.g., forced induction, high RPM, or aggressive tuning).

- You prefer **brand consistency** with your vehicle s original components.

- You re on a **tight budget** and the engine runs stock or lightly modified.

- You re replacing multiple bearings and want to **save costs** without sacrificing quality (brands like **Clevite, Fel-Pro, or Scat** offer excellent options).

- Your engine is **high-performance but not extreme** (e.g., mild turbocharging), and you d prefer **specialized bearings** (e.g., Scat X777 for turbo applications).

For most **stock or mildly modified engines**, a **high-end aftermarket bearing** (e.g., Clevite 262 or Fel-Pro 9000) will perform nearly as well as the Mopar part while being more cost-effective. However, if you re working on a **restoration, classic vehicle, or high-performance build**, the Mopar bearing is a **safe, reliable choice**.
