What is the main advantage of a forged piston over a cast piston?

Forged pistons are made by heating aluminum and forcing it into shape under extreme pressure. This process creates a denser, stronger grain structure compared to cast pistons, making them more resistant to heat and detonation.

Does this piston come with rings or wrist pins?

This listing is for a single piston only. Rings and wrist pins are typically sold separately and should be confirmed before purchase to ensure compatibility.

Can this piston be shipped to California?

No, this piston is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're rebuilding the engine in your Harley-Davidson Evo 1340, a strong piston is key to getting it back on the road reliably. This single forged piston from JE Pistons is built to handle the demands of that V-twin motor. It's designed to fit the stock 3.508-inch bore, making it a direct replacement for a worn-out or damaged piston.

JE Pistons are known for their well-built forged construction, which is significantly stronger than cast aluminum. This means it can better withstand the heat and pressure generated inside the combustion chamber, especially if you're looking to get more performance out of your rebuild. The 3.508-inch bore size is specific to the Evo 1340 engine, ensuring a proper fit and seal within the cylinder.

When you're putting an engine back together, using quality components like this forged piston will make a difference in its longevity and performance. Make sure to check all other necessary components for your rebuild, such as rings, bearings, and gaskets, to ensure a complete and successful engine overhaul.
