CP Pistons are well-known in performance circles for their robust construction and attention to detail. These particular pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process creates a much stronger and more durable piston than cast aluminum, making them ideal for high-performance applications where increased cylinder pressures and temperatures are common. The dish volume of -27.2cc is a key specification that affects your engine's compression ratio, so make sure it aligns with your camshaft, cylinder head, and intended use. The 1.270 inch compression height is also critical for proper piston-to-valve clearance and deck height, ensuring everything fits together correctly within the cylinder block.

Because these pistons are made-to-order, they require a lead time to manufacture. It's also important to note that this product is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation instructions to ensure proper fitment and performance for your specific engine build.
