Review DAMPER DUDES Chevy Harmonic Balancer 6.75 Inch Internal Balance Solid Reman fits 350 SB 1969-88

The **Damper Dudes CH350-2 Harmonic Balancer** is a meticulously engineered, high-performance replacement for the original harmonic balancer found on 1969 through 1988 Chevrolet 350 cubic inch small-block engines, specifically designed for the iconic **SB (Small Block) series** with a **6.75-inch internal balance** a critical detail for maintaining proper crankshaft rotation and reducing vibration in high-performance applications. Crafted from premium **high-strength steel**, this balancer is built to withstand the rigors of aggressive driving, drag racing, and street tuning, offering superior durability compared to stock or aftermarket alternatives that may compromise on material quality or balance precision. The **solid core design** ensures a rigid, vibration-dampening structure that minimizes flex under heavy loads, while the **precision-machined internal balance** guarantees smooth operation and longevity, even under extreme RPM conditions. Whether you're restoring a classic muscle car, building a high-revving street machine, or preparing a competition engine, this balancer delivers the strength, balance, and reliability needed to keep your 350 SB running like new. Its **direct bolt-on compatibility** with the original mounting points ensures an easy installation, while its robust construction eliminates the need for constant adjustments or premature wear making it an essential upgrade for any serious enthusiast seeking peak performance without sacrificing reliability.

### **Pros and Cons of buying a Damper Dudes CH350-2 (1969-88 350 Chevy SB Harmonic Balancer 6.75" Internal Balance, Solid)**

1. **Direct Fit for 1969-1988 350 Chevy Small Block Engines** This balancer is specifically designed for the SB platform, ensuring compatibility without modification.

2. **Solid Construction** The solid design (non-rubber) reduces flex and potential wear over time, which can improve longevity compared to some rubberized alternatives.

3. **Internal Balance (6.75")** The larger internal diameter (6.75") provides better weight distribution and smoother operation, reducing vibration and stress on the crankshaft.

4. **High-Quality Materials** Damper Dudes is known for using durable components, which can help prevent premature failure.

5. **Easier Installation** Since it s a direct replacement, swapping it out is straightforward, requiring minimal additional work.

6. **Potential for Improved Performance** A well-balanced harmonic balancer can reduce engine strain, especially in high-RPM applications or modified engines.

7. **Warranty Coverage** Damper Dudes typically offers warranties on their products, providing some peace of mind against defects.

1. **Higher Upfront Cost** Compared to OEM or aftermarket alternatives, this balancer may be more expensive, especially if buying new.

2. **Solid Design Limitations** While solid balancers are durable, they don t absorb as much vibration as rubberized ones, which can lead to more noticeable engine shake in some cases.

3. **Potential for Looseness Over Time** If not properly torqued or if the mounting bolts stretch, a solid balancer can develop play, leading to rattling noises.

4. **Limited Compatibility with Heavy Modifications** If the engine has significant crankshaft modifications (e.g., oversized rods, extreme displacement), the stock balancer may not be ideal without further adjustments.

5. **No Built-in Damping for High-RPM Vibrations** Unlike rubberized balancers, this one doesn t dampen vibrations at high RPMs, which could be noticeable in high-performance applications.

6. **Requires Proper Installation** If not installed correctly (e.g., incorrect torque, misalignment), it can lead to premature wear or failure.

The **Damper Dudes CH350-2 harmonic balancer** is a solid choice for **1969-1988 350 Chevy SB engines** looking for a durable, direct-fit replacement with improved internal balance. It excels in longevity and compatibility but may not be the best option for engines with extreme modifications or those prioritizing vibration dampening over rigidity.

If your engine runs smoothly and you re looking for a **reliable, long-lasting balancer** without excessive vibration concerns, this is a strong option. However, if you re running a **high-performance or heavily modified engine**, you might want to consider a **rubberized balancer** (like those from **Clevite or JE**) for better vibration control, even if it means slightly less rigidity.

- **Buy it if:** You want a **direct-fit, solid balancer** for stock or mildly modified engines, and you prioritize durability over vibration dampening.

- **Consider alternatives if:** Your engine has **significant modifications**, runs at **very high RPMs**, or you notice excessive vibration in which case a **rubberized balancer** may be preferable.

- **Ensure proper installation** by using the correct torque specs (typically **100-110 ft-lbs** for the bolts) to prevent loosening over time.

For most **stock-to-mildly-modified 350 Chevy engines**, this balancer is a **good investment** that will serve reliably for years.
