Review GM Chevy Inch Hi perfmance Mall Factory Balancer Int Balance fits SB

The **GM 364709 SB Chevy Hi-Performance Balancer** is a precision-engineered, high-performance dynamic balancer designed specifically for General Motors small-block Chevrolet engines, offering unmatched reliability and performance for both street and high-stress applications. Built to exacting standards, this balancer features a robust **cast aluminum housing** that combines lightweight durability with superior heat dissipation, ensuring consistent performance under extreme conditions. The internal design incorporates a **dual-mass construction**, featuring a primary and secondary mass system that effectively isolates vibrations, significantly reducing engine harmonics and enhancing smoothness critical for engines running at high RPMs or under heavy loads. This advanced architecture minimizes torsional vibrations, which can lead to drivetrain fatigue, suspension wear, or even catastrophic failure in aggressive driving scenarios.

At the heart of the GM 364709 SB is a **high-torque, dual-roller bearing assembly**, engineered to handle the rigors of high-performance applications without premature wear. The bearings are precision-machined to maintain optimal alignment and reduce friction, extending the balancer s lifespan while delivering consistent power transfer. The balancer is equipped with a **heavy-duty rubber isolator mount**, which absorbs and dampens vibrations more effectively than traditional metal mounts, reducing noise and preventing transfer of harsh engine pulsations to the drivetrain. This makes it an ideal choice for muscle cars, drag racing setups, and high-revving turbocharged applications where smooth operation is paramount.

For installation flexibility, the GM 364709 SB is compatible with a wide range of GM small-block engines, including naturally aspirated, turbocharged, and supercharged configurations, as well as aftermarket performance builds. The balancer is designed to fit standard GM flexplate mounting patterns, ensuring a straightforward swap for stock or upgraded crankshafts. Its **high-quality counterweights** are dynamically balanced to factory or better specifications, guaranteeing that the engine runs with minimal vibration, even at peak RPMs. Whether used in a daily driver, a high-mileage performance cruiser, or a competition-grade engine, this balancer delivers the precision and durability needed to maintain peak efficiency and longevity.

Built to withstand the demands of extreme performance, the GM 364709 SB is constructed with **high-grade materials and CNC-machined components**, ensuring tight tolerances and superior strength. The balancer s design also incorporates **corrosion-resistant coatings** where necessary, protecting internal components from moisture and debris in harsh environments. For enthusiasts seeking to maximize power output without sacrificing drivetrain integrity, this balancer is a critical upgrade, helping to prevent drivetrain fatigue, improve throttle response, and extend the life of related components like the transmission, driveshaft, and suspension. Whether you're running a stock engine or a heavily modified high-performance setup, the GM 364709 SB Chevy Hi-Performance Balancer is a proven solution for achieving smoother operation, greater reliability, and enhanced performance across the entire RPM range.

### **Pros and Cons of buying a GM 364709 SB Chevy Hi-Performance Balancer (Intake Balance)**

1. **High-Quality Construction** This balancer is designed for high-performance applications, meaning it is built to withstand the stresses of aggressive driving, forced induction, or high-RPM engines. The materials and machining are likely to be robust, reducing the risk of premature failure.

2. **Precision Balancing** The "intake balance" designation suggests it is tuned for specific engine configurations, which can improve drivability, reduce vibration, and enhance throttle response. This is particularly useful in performance engines where smooth operation is critical.

3. **Compatibility with Performance Mods** Since it is marketed as a "hi-performance" part, it is likely designed to work well with turbocharged, supercharged, or high-revving engines where stock balancers may struggle.

4. **Potential for Improved Engine Life** A well-balanced engine runs more smoothly, reducing wear on internal components like crankshafts, rods, and bearings over time.

5. **Aftermarket Support** GM performance parts often have a dedicated following, meaning there are likely resources (forums, tutorials, and replacement parts) available if issues arise.

6. **Potential for Better Throttle Response** Intake-balanced balancers can help reduce turbo lag in forced-induction applications by optimizing airflow and reducing pulsations.

---

1. **Cost** High-performance balancers are typically more expensive than stock or basic aftermarket alternatives. If the engine is not heavily modified, the cost may not justify the upgrade.

2. **Potential Overkill for Stock or Mildly Modified Engines** If the engine is not running at extreme RPMs or under heavy loads, a stock or standard balancer may suffice, making this upgrade unnecessary.

3. **Installation Complexity** Balancer installation often requires removing the crankshaft pulley, timing belt/chain, and possibly the oil pump. If the user lacks mechanical experience, this could lead to mistakes or damage.

4. **Risk of Mismatch with Engine Tuning** If the engine is already tuned for stock components, replacing the balancer without adjusting the tune (if necessary) could lead to poor performance or drivability issues.

5. **Limited Availability of Replacement Parts** While GM parts are common, high-performance balancers may not be as widely stocked as standard components, making future replacements harder to source.

6. **Potential for Vibration Issues if Not Properly Installed** If the balancer is not correctly aligned or balanced, it could introduce new vibrations rather than eliminating them.

---

The **GM 364709 SB Chevy Hi-Performance Balancer (Intake Balance)** is a solid choice for **high-performance or forced-induction applications** where smooth operation, reduced vibration, and optimized airflow are critical. It is particularly beneficial for engines running at high RPMs, under turbocharging, or with aggressive camshafts. However, for **stock or mildly modified engines**, the cost and complexity may not be justified.

If the engine is already heavily modified or if the user is pursuing extreme performance, this balancer could be a worthwhile investment. However, if the engine is not pushing its limits, a standard balancer might be sufficient.

- The engine is turbocharged, supercharged, or heavily modified.

- The user is experiencing excessive vibration or poor throttle response.

- The engine runs at high RPMs frequently.

- The user is comfortable with installation or has a mechanic experienced with balancer swaps.

- The engine is stock or only mildly modified.

- The user is on a tight budget and cannot justify the cost.

- The engine is not tuned for high-performance conditions.

- The user lacks mechanical experience and cannot properly install it.

For best results, **consult with a performance tuner or mechanic** before purchasing to ensure compatibility with the engine s current setup. If in doubt, a **high-quality aftermarket balancer** (such as those from **Clevite, Gates, or Koyo**) may offer a more cost-effective alternative.
