Review MAXPEEDINGRODS 4x Connecting Rods Arp Bolts Mitsubishi Space 1.8 5.248 Inch fits LANCER MIRAGE

The **Maxpeeding Rods 59TUHV 4x ARP 10000 PSI High-Strength Connecting Rods and ARP 10000 PSI Bolts** are a premium, high-performance upgrade designed exclusively for Mitsubishi 4G93 engines found in iconic models like the Lancer, Mirage, and Space Star, all equipped with the 1.8L turbocharged (5.248-inch stroke) configuration. These rods and bolts represent a meticulously engineered solution for enthusiasts seeking to maximize power output, durability, and reliability while pushing the limits of forced induction. Crafted from **forged 4340 steel**, the **59TUHV rods** feature a **5.248-inch stroke length**, precisely matching the stock dimensions while incorporating a **thicker, more robust cross-section** than OEM components. This design enhances rigidity, reduces flex under extreme loads, and minimizes the risk of catastrophic failure critical considerations for engines running high boost levels, aggressive turbocharging, or heavy modifications. The **ARP 10000 PSI bolts** paired with these rods are a game-changer, offering **100,000 psi tensile strength**, significantly surpassing the stock bolts capacity. These bolts are **pre-stretched to 100% of their yield strength** and feature **ARP s proprietary thread-locking compound**, ensuring a permanent, vibration-resistant clamp that prevents loosening under the most demanding conditions. Together, this combination eliminates the weakest link in the crankshaft-to-piston assembly, allowing for **higher boost pressures, increased RPM stability, and prolonged engine life** even under the most aggressive tuning scenarios. Whether you re running a **turbocharged, supercharged, or nitrous-boosted 4G93**, these rods and bolts provide the structural integrity needed to handle the forces generated by modern forced induction setups. The **precision machining and heat treatment** of the rods ensure they meet or exceed OEM tolerances while offering superior fatigue resistance, making them ideal for both street and track applications. For the Mitsubishi 4G93 owner looking to unlock serious power without compromising safety or longevity, the Maxpeeding Rods 59TUHV and ARP 10000 PSI bolts are an indispensable upgrade that bridges the gap between stock reliability and high-performance demands.

**Pros and Cons of Buying Maxpeedingrods 59TUHV 4x Connecting Rods with ARP Bolts for the Mitsubishi 4G93 (Lancer, Mirage, Space 1.8, 5.248" Stroke)**

### **Pros**

1. **Enhanced Durability and Strength** The 59TUHV rods are forged from high-quality 4340 steel, which is significantly stronger than stock rods. This reduces the risk of catastrophic failure under high stress, making them ideal for forced induction or aggressive tuning. The ARP bolts further reinforce the rod-to-crank interface, ensuring better clamping force and reliability.

2. **Improved Performance** The larger 5.248" stroke (compared to the stock 5.125") increases displacement, which can lead to better low-end torque and power output. This is particularly beneficial for naturally aspirated or mildly turbocharged engines, as it allows for more efficient combustion and smoother power delivery.

3. **Compatibility with High-Performance Modifications** The 4G93 engine is a popular platform for tuning, and these rods are designed to handle the stresses of forced induction (turbocharging, supercharging) and high RPM applications. They are a common upgrade for engines running nitrous oxide, aggressive camshafts, or high compression ratios.

4. **Aftermarket Support and Community Trust** Maxpeedingrods is a well-regarded brand in the tuning community, known for producing high-quality, precision-machined components. The combination of rods and ARP bolts is a popular choice among Mitsubishi 4G93 builders, with many positive reviews for reliability and performance gains.

5. **Potential for Increased Reliability** Stock rods on the 4G93 are known to be weak points, especially under heavy loads. Upgrading to these rods eliminates this concern, making the engine more resilient to stress from aggressive driving, modifications, or prolonged high-RPM operation.

6. **Easier Installation and Maintenance** The rods are designed to fit standard crankshafts (assuming the crank is in good condition), and the ARP bolts provide a straightforward, high-torque solution for securing them. Many builders report that the installation process is manageable with basic tools and mechanical experience.

### **Cons**

1. **Cost** The price of these rods and bolts is significantly higher than stock components. A full set of 4x rods with ARP bolts can cost several hundred dollars, which may be a substantial investment for a naturally aspirated engine or a project car. This cost must be justified by the level of tuning or performance gains you intend to achieve.

2. **Requires Additional Modifications** Simply installing these rods may not be enough to fully realize their potential. To safely and effectively use them, you may need to pair them with other upgrades such as:

- A stronger crankshaft (if the stock one is worn or weak).

- Upgraded pistons (to match the increased stroke and stress).

- A reinforced oil pump or upgraded lubrication system.

- A tuned ignition system or fuel delivery (for forced induction).

- A stronger clutch and transmission (if the engine is being used for high-power applications).

These additional costs can add up quickly.

3. **Potential for Overkill on Mildly Tuned Engines** If your engine is only mildly modified (e.g., stock or with minor upgrades like a cold air intake), the benefits of these rods may not be significant enough to justify the cost. In such cases, the stock rods might suffice, and the extra money could be better spent on other performance upgrades (e.g., exhaust, suspension, or drivetrain components).

4. **Installation Complexity** While the rods themselves are straightforward to install, the process requires careful attention to detail. Improper installation (e.g., incorrect torque specs for ARP bolts, misalignment, or damage to rod journals) can lead to failure. If you lack mechanical experience, you may need to consult a professional, which adds to the cost.

5. **Weight** Forged rods are heavier than stock cast rods. While the weight difference is minimal in most cases, it may have a negligible impact on handling or acceleration in high-performance applications where every gram counts.

6. **Limited Stock Availability** These are aftermarket parts, and while they are widely available, they may not be as easily accessible as OEM components. You ll need to order them from a reputable supplier, which could involve shipping delays or potential counterfeit risks if purchasing from untrusted sources.

### **Conclusion**

The Maxpeedingrods 59TUHV 4x connecting rods with ARP bolts are a **high-quality, performance-oriented upgrade** for the Mitsubishi 4G93 engine, particularly if you are planning significant modifications such as forced induction, nitrous, or aggressive tuning. They offer **superior durability, increased displacement, and reliability**, making them a strong choice for builders who prioritize long-term engine integrity and power gains.

However, they are **not a necessary upgrade for stock or mildly modified engines**, as the cost and additional requirements may not be justified. If you are running a naturally aspirated engine with minimal modifications, the stock rods might be sufficient, and the money could be better spent elsewhere.

For **forced induction or high-stress applications**, these rods are an excellent investment. They are a **popular and trusted choice** in the 4G93 community, and when paired with complementary upgrades (strong crank, pistons, fueling, etc.), they can significantly enhance the engine s lifespan and performance.

---

### **Recommendation**

- You are running or planning forced induction (turbo/supercharger).

- You are using nitrous oxide or aggressive camshafts.

- You want to increase displacement for better low-end torque.

- You are building a high-performance or competition engine where reliability is critical.

- You are willing to invest in a full engine support package (crank, pistons, fueling, etc.).

- Your engine is stock or only mildly modified (e.g., intake, exhaust, minor tuning).

- You are on a tight budget and can achieve similar performance gains with less expensive upgrades.

- You lack the mechanical experience to install them correctly or support them with additional modifications.

**Final Verdict:** For serious tuners and builders pushing the 4G93 engine, these rods are a **worthwhile upgrade** that pays off in reliability and performance. For casual or lightly modified engines, they are **overkill** and may not be the best use of your budget. Always ensure that the rest of your engine is properly supported to maximize the benefits of these rods.
