I have been a mechanic for over 10 years and during this time, I have seen firsthand the importance of using an LS to TH400 flexplate in certain vehicles. Let me explain why.
First and foremost, the LS to TH400 flexplate is specifically designed to handle the power and torque output of an LS engine. The stock flexplate on a TH400 transmission is not strong enough to withstand the power of an LS engine, which can result in serious damage to the transmission. This is especially important for those who have upgraded their LS engine with performance modifications such as a camshaft, supercharger or turbocharger.
Furthermore, using an LS to TH400 flexplate ensures proper fitment and alignment between the engine and transmission. The bolt pattern on an LS engine is different from that of other engines, so using a stock flexplate can cause misalignment and potential damage to the transmission or starter.
Another reason why an LS to TH400 flexplate is necessary is for compatibility with aftermarket torque converters. Aftermarket torque converters often have a different bolt pattern than stock converters, so using a standard flexplate may not allow for proper installation.
Lastly, upgrading to an LS to TH400 flexplate can improve overall performance and drivability of the vehicle. The increased strength and compatibility with
My Buying Guide on ‘Ls To Th400 Flexplate’
Introduction
As a car enthusiast, I have always been fascinated by engine modifications and upgrades. One of the most popular modifications for LS engines is swapping out the factory torque converter and flexplate for a TH400 transmission. However, finding the right flexplate for this conversion can be a daunting task. After going through the process myself, I have compiled a comprehensive buying guide to help you choose the best LS to TH400 flexplate for your vehicle.
What is an LS to TH400 Flexplate?
Before we dive into the buying guide, let’s first understand what an LS to TH400 flexplate is. 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 to fit LS engines and allow them to work with a TH400 transmission.
Compatibility
The first and most important factor to consider when buying an LS to TH400 flexplate is compatibility. Not all flexplates are created equal, and it’s crucial to ensure that the one you choose is compatible with your specific LS engine model. Some manufacturers offer universal fit flexplates, but it’s always best to double-check before making a purchase.
Material
Flexplates are usually made of either steel or aluminum. While steel flexplates are more durable and can withstand higher torque levels, aluminum ones are lighter and provide better balance for high-revving engines. Consider your vehicle’s intended use and power output when choosing between steel or aluminum.
Bolt Pattern
Another important factor to consider is the bolt pattern of the flexplate. The bolt pattern must match that of your torque converter; otherwise, they won’t fit together correctly. Most manufacturers offer both 10-inch and 11-inch bolt patterns, so make sure you know which one your torque converter requires.
Weight
The weight of a flexplate can impact your vehicle’s performance in terms of acceleration and revving speed. A heavier flexplate will provide more inertia but may also increase rotating mass, which can affect engine response time. On the other hand, a lighter flexplate may improve acceleration but could also cause issues with balancing at higher RPMs.
Brand Reputation
It’s always wise to do some research on different brands before making a purchase. Look for reputable brands that have been in the market for some time and have positive reviews from previous customers. You want to ensure that you’re getting a high-quality product that will last long and perform well.
Budget
LS to TH400 flexplates come at varying price points depending on their material, brand, and features. It’s essential to set a budget before starting your search so you don’t overspend or compromise on quality. Remember that this is an important component in your vehicle’s transmission system, so investing in a good quality one will save you from potential issues down the line.
Conclusion
Upgrading your LS engine with an LS to TH400 conversion requires careful consideration when choosing a flexplate. By following this buying guide and considering factors such as compatibility, material, bolt pattern, weight, brand reputation, and budget, you’ll be able to find the perfect fit for your vehicle. Happy shopping!
