JE Pistons Aprilia Mana/John Deere RSX 850I Piston Single

This is a single forged piston from JE Pistons, part number 317220S, designed for the Aprilia Mana and John Deere RSX 850I. If you're rebuilding or upgrading the engine in one of these machines, a well-built piston like this is crucial for reliable performance. JE Pistons is a well-known name in high-performance engine components, and this piston reflects that reputation.

Forged pistons are made by shaping aluminum under extreme pressure, which creates a denser, stronger grain structure compared to cast pistons. This makes them more resistant to the high temperatures and pressures found in performance engines. This particular piston is designed as a direct replacement or upgrade, meaning it should fit right into your existing engine assembly with the proper supporting components and installation procedures. Its construction aims to handle the demands of these specific applications, offering a solid option for engine work.

When undertaking an engine rebuild, it's always a good idea to consult the manufacturer's service manual for the correct installation procedures and specifications. Ensure all supporting components, such as rings, connecting rods, and bearings, are also in good condition or replaced as needed for optimal engine health.
