This is a single JE Pistons 4-valve piston, measuring 3.937 inches in diameter. It's built for Suzuki engines that use a 4-valve cylinder head configuration, often found in performance applications where improved airflow and combustion efficiency are key. If you're rebuilding or upgrading your engine, a well-made piston like this is fundamental to its performance and reliability.

JE Pistons are known for their robust construction, and this particular piston is forged, meaning it starts as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable part than cast pistons, making it suitable for higher compression ratios and more demanding engine conditions. The 3.937-inch bore size is specific, so ensure it matches your engine's requirements for a proper fit and optimal performance. This piston is sold individually, allowing you to replace exactly what you need or build a custom set.
