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

Forged pistons are made by heating and hammering aluminum into shape, which creates a stronger and more durable part. This makes them better suited to handle the high pressures and temperatures found in performance or heavily used engines compared to cast pistons.

Do I need to buy more than one of these pistons for my engine?

This listing is for a single piston. If your engine has multiple cylinders that require replacement, you will need to order the appropriate quantity to match the number of cylinders you are rebuilding.

Is this piston compatible with California emissions standards?

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

Product Details

This JE Pistons 3.528 inch bore piston is built for Harley-Davidson 1200cc Sportster engines. It's a single piston designed to replace a worn or damaged unit, helping to restore your engine's performance. The 3.528 inch bore size is a specific measurement that ensures a proper fit within the cylinder, which is crucial for good compression and efficient combustion.

JE Pistons are known for their well-built forged construction, which means this piston is made from a solid block of aluminum that's heated and hammered into shape. This process creates a stronger, more durable part than cast pistons, making it better able to withstand the high pressures and temperatures inside your engine. This particular piston is designed as a single replacement, so you'll need to order the correct quantity if you're rebuilding multiple cylinders.

When installing this piston, remember that it's intended for specific Harley-Davidson 1200cc Sportster applications. Always refer to your service manual for the correct installation procedures and specifications to ensure a proper rebuild.
