Pros and Cons of Buying a 20237 7.850 Chromoly Push Rod Set for GM Gen LT1/LT4 Engines

Introduction:

The 20237 7.850 Chromoly Push Rod Set is a popular aftermarket upgrade for GM Gen LT1 and LT4 engines. This set, manufactured by Manley Performance, is made of chromoly material to provide enhanced durability and performance. In this article, we will discuss the pros and cons of buying this push rod set to help you make an informed decision.

Pros:

1. Enhanced Durability: Chromoly material is known for its durability and resistance to fatigue. By using this material for the push rods, the set is less likely to fail under heavy load or high RPMs, making it ideal for high-performance applications.

2. Improved Performance: Chromoly push rods can help improve engine performance by reducing the weight of the valvetrain. Lighter push rods help to reduce engine friction and allow the valves to move more freely, which can lead to increased horsepower and torque.

3. Better Compatibility: The 20237 7.850 Chromoly Push Rod Set is designed specifically for GM Gen LT1 and LT4 engines, ensuring a perfect fit and eliminating the need for any modifications or customization.

4. OEM-Quality: Manley Performance is known for producing OEM-quality parts, and this push rod set is no exception. The set comes with detailed instructions, high-quality materials, and precise tolerances to ensure a smooth installation and reliable operation.

Cons:

1. Cost: The 20237 7.850 Chromoly Push Rod Set is more expensive than the OEM push rods. The price difference may be a significant factor for some buyers, especially those on a tight budget.

2. Installation Complexity: Installing aftermarket push rods can be more complicated than installing OEM parts. It may require specialized tools, and the process may take longer than a standard installation.

3. Potential Engine Noise: Some users have reported an increase in engine noise after installing aftermarket push rods, including the 20237 Chromoly set. This noise may be due to the lighter weight of the rods, which can cause the valves to slam shut more forcefully.

Conclusion:

The 20237 7.850 Chromoly Push Rod Set offers several advantages, including enhanced durability, improved performance, better compatibility, and OEM-quality manufacturing. However, it comes with a higher price tag and may require a more complex installation process. Additionally, some users have reported an increase in engine noise. Ultimately, the decision to buy this push rod set depends on your budget, performance goals, and installation capabilities.

Recommendation:

If you are looking to upgrade your GM Gen LT1 or LT4 engine with a more durable and high-performance push rod set, the 20237 7.850 Chromoly Push Rod Set from Manley Performance is an excellent choice. However, be prepared for a higher cost, potential installation complications, and the possibility of increased engine noise. If you are on a tight budget or prefer a quieter engine, you may want to consider other options or wait for a sale on this push rod set.
