What sets the SCAT 26135P apart is its **full-floating design**, where the rod bolts are securely retained by **high-strength, hardened steel caps** held in place by **Grade 8 or ARP fasteners** (sold separately), eliminating the risk of bolt stretch or failure an all-too-common issue in high-performance applications. The **smooth, polished rod journals** and **crankpin surfaces** reduce wear on bearings, extending their lifespan and ensuring consistent power delivery across the entire rev range. Whether paired with a **SCAT forged crankshaft** for a complete high-performance assembly or integrated into a custom engine build, this rod is engineered to handle **forced induction, nitrous applications, and extreme torque loads** with confidence. Built to withstand the rigors of **drag racing, street tuning, and professional motorsports**, the SCAT 26135P connecting rod is a testament to SCAT s commitment to **precision, performance, and reliability**, making it an indispensable choice for builders seeking the ultimate in internal combustion strength.
### Pros and Cons of Buying a Scat Crankshaft (Part Number 26135P) with a Connecting Rod
#### **Pros:**1. **High Performance and Durability** Scat cranks are engineered for high-performance applications, including forced induction (turbo/supercharged) and high-RPM use. They are built with precision machining and heat-treated materials to withstand extreme stress, making them ideal for modified engines.
2. **Balanced and Smooth Operation** Scat cranks are dynamically balanced, reducing vibration and improving engine smoothness. This is particularly beneficial in high-revving engines where imbalance can lead to premature wear or failure.
3. **Compatibility with Aftermarket Parts** Scat offers cranks that are designed to work seamlessly with aftermarket components, including forged pistons, high-flow heads, and turbochargers. This makes them a popular choice for builders looking to maximize power output.
4. **Warranty and Support** Scat is a reputable brand with a strong reputation for quality. Their cranks come with warranties, and they provide technical support for installation and tuning, which can be valuable for serious engine builders.
5. **Customization Options** Scat offers various crankshaft designs, including those with different journal sizes, stroke lengths, and counterweight configurations. This allows builders to tailor the crank to specific engine requirements, whether for street, drag, or racing applications.
6. **Proven Track Record** Scat cranks have been used in professional racing and high-performance applications for decades. Their reliability in extreme conditions gives builders confidence in their performance.
7. **Reduced Risk of Failure** Compared to stock cranks, Scat cranks are less likely to fail under heavy loads or high stress, which can prevent catastrophic engine damage.

#### **Cons:**1. **Higher Cost** Scat cranks are significantly more expensive than stock or aftermarket alternatives from lesser-known brands. The premium price reflects their quality and performance, but it can be a substantial investment for budget-conscious builders.
2. **Specialized Installation Requirements** Installing a Scat crank often requires additional modifications, such as machining the block, using high-quality bearings, and ensuring proper alignment. This may involve extra labor costs or specialized tools, adding to the overall expense.
3. **Limited Availability of Stock Parts** If you re working with a stock engine block, you may need to source compatible rods, bearings, and other components separately. Some aftermarket parts may not be directly compatible without modifications.
4. **Potential Overkill for Mild Modifications** If your engine is only lightly modified (e.g., mild tuning or minor upgrades), a Scat crank may be more power than you need. In such cases, a less expensive aftermarket crank or a stock crank with reinforcement could suffice.
5. **Learning Curve for Builders** High-performance cranks require careful attention to detail during installation. Improper assembly (e.g., incorrect bearing clearance, misaligned rods, or insufficient lubrication) can lead to premature failure. Builders may need to invest time in research or consult with professionals.
6. **Weight Considerations** While Scat cranks are durable, some high-performance designs may be slightly heavier than stock cranks. This can affect drivability in high-revving applications where weight reduction is desirable.
7. **Compatibility Issues with Certain Blocks** Some older or less common engine blocks may not be fully compatible with Scat cranks due to differences in rod bolt patterns, main cap designs, or crankshaft dimensions. This could require additional machining or custom parts.

### **Conclusion:**A Scat crankshaft (26135P) is an excellent choice for serious engine builders, racers, or those pursuing significant power gains through forced induction or high-RPM operation. Its superior durability, balance, and compatibility with aftermarket parts make it a reliable investment for high-performance applications. However, the higher cost, specialized installation requirements, and potential overkill for mild modifications mean it may not be the best option for casual tuners or those on a tight budget.
For most **high-performance street, drag, or racing applications**, the benefits of a Scat crank outweigh the drawbacks. If your project involves heavy modifications, forced induction, or extreme stress on the crankshaft, the investment is justified. Conversely, if you re working with a stock or lightly modified engine, a more budget-friendly alternative may be sufficient.

### **Recommendation:** - **Buy the Scat crankshaft if:**- You are building a high-performance engine for racing, heavy-duty street use, or forced induction.
- You have the budget and are willing to invest in components that will last under extreme conditions.
- You plan to pair it with other high-quality aftermarket parts (e.g., forged rods, premium bearings, turbochargers).
- You are comfortable with the installation process or have access to a professional mechanic.
- **Consider alternatives if:**- Your engine modifications are mild (e.g., basic tuning or minor upgrades).
- You are working with a limited budget and can achieve adequate performance with a less expensive crank.
- Your engine block has compatibility issues that would require extensive modifications.
- You prioritize weight reduction over absolute durability (though Scat cranks are still strong in this regard).
Ultimately, the Scat 26135P crankshaft is one of the best options available for high-performance applications, but it s essential to weigh its advantages against your specific project requirements.
