Review MOLNAR TECHNOLOGIES Mopar Slant Connecting Rods Use Forged Crankshaft

The **MOLNAR DH7005UHB6-A Mopar Slant 318/360 Connecting Rods for Forged Crankshaft** are a premium, high-performance replacement set designed exclusively for the iconic **Chrysler 318/360 cubic inch Slant-6 engine**, a legendary powerplant renowned for its durability and versatility in muscle cars, trucks, and classic vehicles. Engineered with meticulous precision, these **forged steel connecting rods** feature a **6.000-inch bolt circle** and are **fully counterweighted** to ensure optimal balance and strength, critical for handling the high RPM demands and torque loads of both stock and modified Slant-6 applications. Each rod is **heat-treated to an impressive tensile strength of 140,000 PSI**, guaranteeing exceptional fatigue resistance and the ability to withstand extreme stress without warping or failure, even under aggressive forced induction or high-compression builds. The **split-pin design** secures the rod caps with **M12 x 1.25mm bolts** (included), providing a robust and reliable clamping force that minimizes rod end movement and prevents catastrophic failure an essential upgrade for engines running nitrous oxide, turbocharging, or heavy-duty towing setups. Crafted from **high-grade 4340 alloy steel**, these rods are **shot-peened** for enhanced surface hardness and fatigue life, while their **polished rod journals** ensure smooth bearing operation, reducing friction and extending bearing life. The **precision-machined oil holes** and **optimized rod length** (3.750 inches) maintain proper crankshaft alignment and minimize side loading on the bearings, contributing to a cleaner-running, more efficient engine. Whether restoring a vintage Slant-6 to factory specifications or pushing a modified engine to new performance limits, these **MOLNAR rods** deliver the strength, reliability, and performance-enhancing benefits that serious builders demand. Backed by MOLNAR s reputation for quality and a **lifetime warranty**, they represent a smart investment for anyone seeking to maximize the longevity and power potential of their Chrysler 318/360 engine.

### Pros and Cons of Buying Mopar Slant 6 Forged Crankshaft Connecting Rods (Molnar DH7005UHB6-A)

#### **Pros:**

1. **Compatibility and Fitment** These rods are specifically designed for the Mopar Slant 6 engine, ensuring a precise fit with the forged crankshaft. They are built to match the original engine specifications, reducing the risk of clearance issues or interference.

2. **High-Quality Materials** Molnar rods are forged from high-strength steel, which provides superior durability and resistance to fatigue compared to cast rods. This makes them suitable for both stock and performance applications, including forced induction builds.

3. **Balanced and Polished** The rods undergo precise machining and balancing to ensure smooth operation and reduced vibration. Proper polishing of the rod journals and caps helps maintain oil flow and reduces wear.

4. **Aftermarket Support and Availability** Molnar is a well-established manufacturer with a strong reputation in the performance and restoration market. These rods are widely available through reputable parts suppliers, making sourcing easier.

5. **Potential for Performance Upgrades** While these rods are stock-length, they are often used in builds where slight modifications (like longer rods for increased compression) are made. Their robust construction allows for minor adjustments without compromising strength.

6. **Warranty and Reliability** Molnar products typically come with a warranty, providing peace of mind against manufacturing defects. Their reputation for reliability makes them a trusted choice for engine builders.

7. **Cost-Effective for Restoration** If you re restoring a Slant 6 engine, replacing the rods with Molnar s forged options can be more cost-effective than sourcing original OEM parts, which may be scarce or expensive.

#### **Cons:**

1. **Stock-Length Limitations** These rods are designed for the original Slant 6 crankshaft and are not oversized or longer than stock. If you re planning significant modifications (e.g., a larger bore or significant compression ratio increase), you may need longer rods to avoid interference with the pistons.

2. **Installation Complexity** Installing aftermarket rods requires careful attention to torque specifications, alignment, and gapping. Improper installation can lead to rod bearing failure or catastrophic engine damage. This may require professional assistance if you lack experience.

3. **Cost Compared to Cast Rods** While forged rods are more durable, they are also more expensive than cast rods. For a stock or lightly modified engine, cast rods might suffice and save money without sacrificing reliability.

4. **Potential for Overkill** If your engine is running stock or with minimal modifications, the extra strength of forged rods may not be necessary. Forged rods are best suited for high-performance or heavily modified engines where stress is significantly increased.

5. **Compatibility with Non-Stock Crankshafts** If you re using a non-Mopar crankshaft (e.g., a Chevy or Ford crate crank), you ll need to verify that the rod dimensions match the crank s journal size and bolt pattern. Molnar rods are optimized for Mopar cranks, so mismatches could occur.

6. **Time-Consuming Rebuild** Replacing rods as part of an engine rebuild adds time and labor costs. If you re on a tight schedule or budget, this may be a drawback compared to using original or less expensive parts.

### **Conclusion:**

Molnar DH7005UHB6-A forged connecting rods are an excellent choice for Mopar Slant 6 engines, especially if you re pursuing performance modifications, forced induction, or a high-mileage restoration. Their forged construction, precise machining, and compatibility with the stock crankshaft make them a reliable upgrade. However, they may not be necessary for stock or lightly modified engines where cast rods would suffice. The decision ultimately depends on your engine s goals, budget, and intended use.

If you re building a **high-performance Slant 6** (e.g., turbocharged, supercharged, or high-RPM application), these rods are a strong recommendation due to their strength and durability. For a **stock or mildly modified engine**, they offer peace of mind but may be overkill. Always ensure proper installation and consider consulting an engine builder if you re unsure about compatibility or torque specifications.

**Final Recommendation:** Purchase the Molnar DH7005UHB6-A rods if:

- You re modifying your Slant 6 for performance (turbo, supercharger, or high-RPM use).

- You want forged rods for added strength and longevity, even in stock applications.

- You re restoring an engine and want high-quality, reliable parts.

Avoid them if:

- Your budget is tight and you re only doing minimal modifications.

- You re using a non-Mopar crankshaft and haven t verified rod compatibility.

- You lack experience with rod installation and prefer to leave it to a professional.
