The **Maxpeeding Rods ZAE4VD 4x ARP 2000 5.657" Connecting Rods** are a premium, high-performance upgrade designed specifically for the **Mitsubishi 4B12 2.4L inline-four engine**, offering unmatched strength, reliability, and durability for both street and track applications. Engineered to exceed the factory rod s limitations, these rods are crafted from **forged 4340 chrome-molybdenum steel**, a material renowned for its exceptional fatigue resistance, tensile strength, and ability to withstand extreme stress without deformation. Each rod is **precision-machined to ARP s proprietary 2000 series specifications**, ensuring a near-perfect balance of weight, stiffness, and load-bearing capacity, which translates to improved power transfer, reduced vibration, and enhanced engine longevity. The **5.657-inch bolt circle** is meticulously maintained, guaranteeing seamless compatibility with the stock crankshaft and main bearings while allowing for a slight increase in displacement or compression ratios if desired. The rods feature **ARP s signature high-strength ARP 2000 bolts**, which are heat-treated to **200,000 PSI tensile strength**, eliminating the risk of bolt stretch or failure under high RPM or aggressive driving conditions. Unlike aftermarket rods that may compromise on material quality or machining precision, these rods are **fully balanced and dynamically tested** to ensure flawless operation, even under extreme loads. Whether you're pushing the limits on the track, modifying for increased horsepower, or simply seeking a bulletproof upgrade for daily driving, these rods deliver the ultimate combination of strength and performance. Built to withstand the rigors of forced induction, nitrous, or high-revving applications, the **ZAE4VD rods** are a game-changer for Mitsubishi 4B12 engines, offering a direct path to greater reliability and power without sacrificing durability.
### **Pros and Cons of Buying Maxpeedingrods ZAE4VD 4x ARP 2000 Connecting Rods for the Mitsubishi 4B12 2.4L Engine**
#### **Pros:**1. **Enhanced Durability and Strength** ARP 2000 rods are forged from high-strength steel, significantly improving resistance to fatigue, bending, and torsional stress compared to stock rods. This is particularly beneficial for high-performance applications, forced induction, or aggressive driving styles.
2. **Increased Compression Ratio Tolerance** The 4B12 engine is known for its tendency to suffer from rod failure under high compression (especially with turbocharging or nitrous). These rods are designed to handle higher loads, reducing the risk of catastrophic failure.
3. **Better Weight Distribution** The rods are slightly heavier than stock, which can improve inertia and reduce flex under extreme loads, leading to better power delivery and longevity.
4. **Compatibility with Aftermarket Parts** The ZAE4VD kit is specifically designed for the 4B12, ensuring proper fitment with common upgrades like turbochargers, superchargers, or high-flow heads.
5. **Warranty and Reputation** ARP is a well-respected brand in the performance parts industry, offering a strong warranty (typically 1 year) and a proven track record in high-performance applications.
6. **Potential for Increased Power Output** By reducing the risk of rod failure, these rods allow for more aggressive tuning, enabling higher boost levels, larger turbos, or more aggressive camshafts without immediate failure concerns.
7. **Retains Stock Dimensions** The rods maintain the same bolt pattern and length as stock, meaning no modifications to the engine block or crankshaft are required for installation.
---
#### **Cons:**1. **Cost** ARP rods are significantly more expensive than stock or aftermarket alternatives (e.g., OEM replacement rods or budget brands). The ZAE4VD kit (4x rods) will likely cost several hundred dollars, making it a substantial investment.
2. **Installation Complexity** Replacing connecting rods requires significant mechanical skill, specialized tools (rod jig, torque wrench, etc.), and disassembly of the engine. If not done correctly, it can lead to further damage or improper fitment.
3. **Potential for Overkill** If the engine is not heavily modified (e.g., stock or mild turbo), the stock rods may still be adequate. Upgrading to ARP rods may be unnecessary unless planning significant power increases.
4. **Maintenance and Cost of Engine Work** Installing these rods requires a full engine teardown, which includes labor costs if done professionally. This may not be practical for casual drivers or those with limited budgets.
5. **Risk of Improper Installation** If not installed correctly (e.g., incorrect torque, misalignment, or improper bearing clearance), the rods could fail prematurely or cause engine damage. This requires precision and experience.
6. **Limited Availability of Parts** While ARP is reliable, finding a local mechanic familiar with their installation may be difficult in some areas, potentially requiring shipping or specialized labor.
7. **Not a Cure for Poor Engine Condition** If the engine has existing wear (e.g., cracked blocks, worn crankshafts, or poor maintenance history), upgrading rods alone will not fix underlying issues. A full engine rebuild may still be necessary.

### **Conclusion:**The **Maxpeedingrods ZAE4VD ARP 2000 connecting rods** are a **highly recommended upgrade** for the **Mitsubishi 4B12 2.4L engine** if you are planning **forced induction (turbo/supercharger), aggressive tuning, or high-performance applications**. They provide **superior strength, reliability, and peace of mind** compared to stock rods, especially in scenarios where the engine is pushed beyond its original limits.
However, they are **not a necessary upgrade** for **stock or mildly modified engines** where the stock rods remain adequate. The **cost, installation difficulty, and potential overkill** for low-power applications must be weighed against the benefits.
If you are **serious about building a high-performance 4B12** (e.g., turbocharged, nitrous, or high-compression builds), these rods are a **wise investment** to prevent catastrophic failure. If you are on a budget or only doing mild modifications, consider **stock rods or a less expensive alternative** until you reach a power level where rod failure becomes a real risk.
### **Recommendation:** - **Buy the ARP rods if:**- You are running or planning **forced induction (boost >10 psi, nitrous, or large turbos).**
- You are building a **high-compression, high-RPM engine** (e.g., 10:1 CR with forced induction).
- You want **maximum reliability** and are willing to invest in **long-term engine durability.**
- You have **mechanical experience** or are working with a **trusted engine builder.**
- **Avoid or delay purchasing if:**- Your engine is **stock or mildly modified** (e.g., stock turbo, no nitrous, low boost).
- You are **not comfortable with engine disassembly** or lack access to a **qualified mechanic.**
- You are **operating on a tight budget** and can achieve your goals with less expensive upgrades.
For best results, pair these rods with a **full engine support package** (e.g., ARP main studs, upgraded crankshaft, high-quality bearings, and proper lubrication). Always follow **ARP s installation guidelines** and consult a **performance engine specialist** before installation.
