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

Forged pistons are made by shaping aluminum alloy under extreme pressure. This process creates a stronger, more durable grain structure that can better withstand the high heat and pressure of performance engines compared to cast pistons.

Does this piston come with rings or a wrist pin?

This listing is for a single piston only. Rings and wrist pin are typically sold separately, so please check the product details or add them to your cart if needed for your rebuild.

Can this piston be used in California?

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

Product Details

Forged from high-strength aluminum alloy, this JE Pistons single piston is built for the demands of Harley-Davidson Twin Cam 103 engines. The material choice offers a good balance of light weight and durability, crucial for performance and longevity in a high-compression environment. This piston is designed as a direct replacement, meaning it fits right into the existing cylinder bore without modification, assuming the bore is within spec. It's a solid option if you're rebuilding the top end or looking to replace a damaged piston.

JE Pistons is a well-known name in performance engine components, and this piston reflects that reputation. The forging process creates a stronger, more uniform grain structure compared to cast pistons, which helps it withstand the higher pressures and temperatures found in performance applications. While this piston is designed for a specific engine configuration, it's always a good idea to check the exact bore and stroke specifications for your particular Twin Cam 103 build to ensure optimal performance and fit. Remember, this part is not CARB approved and cannot be shipped to California.
