About this part

Product Details

This adapter plate from Clutch Masters is machined from a solid block of 6061-T6 aluminum, a strong yet lightweight material chosen for its durability and ease of machining. It's designed to connect a Chevrolet LS-series engine to a Subaru transmission, allowing you to swap a powerful LS V8 into a Subaru chassis. This specific plate is 0.75 inches thick, providing the necessary spacing and alignment for a proper drivetrain connection.

Swapping an LS engine into a Subaru chassis is a popular modification for those seeking a significant power increase. This adapter plate is a critical component in making that swap a reality, ensuring that the engine and transmission bolt up correctly. Clutch Masters has engineered this plate to be a direct fit for the specified components, meaning you won't need to modify the transmission bellhousing or the engine block itself for the plate to mount. The precise machining ensures that the crankshaft centerline of the LS engine aligns with the input shaft centerline of the Subaru transmission, which is crucial for drivetrain longevity.

When undertaking an LS to Subaru transmission swap, you'll also need to consider other supporting components. This adapter plate is designed to work with the factory Subaru transmission bellhousing and the Chevrolet LS engine's rear main seal area. You will need to source appropriate hardware to bolt the plate to both the engine and the transmission, as well as a compatible flywheel or flexplate and clutch assembly. Clutch Masters is known for producing well-built drivetrain components, and this adapter plate is no exception, offering a solid solution for your LS swap project.
