Why I Recommend Using an LS to TH400 Flexplate
As a car enthusiast and mechanic, I have worked on countless engine swaps and upgrades. One of the most common upgrades is replacing the stock engine with an LS engine, known for its power and reliability. However, when it comes to mating an LS engine with a TH400 transmission, many people overlook the importance of using a proper flexplate.
The flexplate is a critical component that connects the engine to the transmission and allows for smooth power transfer. The stock flexplate on the TH400 is designed for use with a traditional small block Chevy engine, not an LS. This means that it may not have the correct bolt pattern or starter ring gear size for the LS engine, leading to potential problems during installation.
Using an LS to TH400 flexplate solves this issue by providing the correct bolt pattern and starter ring gear size for the LS engine. This ensures that there are no compatibility issues during installation and guarantees proper alignment between the engine and transmission.
Another reason why I highly recommend using an LS to TH400 flexplate is for its strength and durability. The stock flexplate may not be able to handle the increased power and torque of an LS engine, leading to premature wear or even failure.
My Buying Guide on ‘Ls To Th400 Flexplate’
As someone who has recently upgraded my LS engine to a TH400 transmission, I understand the importance of finding the right flexplate for this conversion. After researching and testing out different options, I have put together a buying guide to help others in their search for the perfect LS to TH400 flexplate.
What is an LS to TH400 Flexplate?
A flexplate is a circular metal disc that connects the engine’s crankshaft to the torque converter in an automatic transmission. The LS to TH400 flexplate is specifically designed for LS engines and TH400 transmissions, allowing them to work together seamlessly.
Why Do I Need an LS to TH400 Flexplate?
If you are upgrading your LS engine to a TH400 transmission, you will need an LS to TH400 flexplate. This is because the bolt pattern on the crankshaft of an LS engine is different from that of a traditional small block Chevy engine. The flexplate ensures that these two components can be properly connected and function together.
Factors to Consider
- Material: The material of the flexplate is important as it affects its strength and durability. Look for one made from high-grade steel or aluminum for maximum performance.
- Tooth Count: The tooth count on the flexplate should match that of your torque converter. This ensures proper fitment and avoids any potential issues with starting or shifting.
- Bolt Pattern: As mentioned earlier, the bolt pattern on an LS engine is different from traditional small block Chevy engines. Make sure the flexplate you choose has the correct bolt pattern for your specific engine model.
- Balancing: Some flexplates come already balanced while others may require balancing before installation. It is important to check this before purchasing as unbalanced components can cause vibrations and damage to your engine.
Tips for Installation
- Cleanliness: Before installing the new flexplate, make sure both surfaces (crankshaft and torque converter) are clean and free from any debris or oil residue.
- Torque Specs: When tightening the bolts, make sure to follow the manufacturer’s recommended torque specs. This will ensure proper fitment and avoid any potential issues down the road.
- Bolt Locking Mechanism: To prevent any bolts from coming loose during operation, it is recommended to use a thread-locking compound or lock washers when installing the bolts onto the crankshaft.
In Conclusion
An LS to TH400 flexplate may seem like a small component in your engine conversion project, but it plays a crucial role in ensuring proper functionality and performance of your vehicle. By considering factors such as material, tooth count, bolt pattern, and balancing when making your purchase decision, you can rest assured that you have chosen a quality product that will meet your needs.
I hope my buying guide has been helpful in your search for an LS to TH400 flexplate. Happy shopping!
