Description

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.
