If you're rebuilding the engine in your Harley-Davidson 1340cc motorcycle, a strong, well-made piston is crucial for reliable performance. This single forged piston from JE Pistons is built to handle the demands of a high-compression V-twin. It's designed as a direct replacement for your stock piston, ensuring it fits right into your existing engine assembly.

JE Pistons are known for their robust construction, and this particular piston is forged from high-strength aluminum alloy. This forging process creates a denser, more durable component than cast pistons, making it better able to withstand the heat and pressure generated in a performance engine. The 3.508-inch bore size is specific to the Harley-Davidson 1340cc engine, often referred to as the Evolution or Evo engine. This piston is sold individually, so you can replace exactly what you need or build a complete set for your project.
