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

Forged pistons are made by shaping aluminum under extreme pressure, which creates a denser and stronger material. This makes them more resistant to heat and stress, ideal for performance applications or engines that will be pushed harder than stock.

Does this piston come with rings or a wrist pin?

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

Can I ship this piston 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 top end of your Milwaukee 8 engine, a strong set of forged pistons is key to handling increased performance or just ensuring long-term reliability. These single pistons from JE Pistons are built for that purpose. They are designed to be a direct replacement for the stock piston, making the rebuild process more straightforward.

JE Pistons are well-known in the performance engine world, and these are made from a strong aluminum alloy that's forged for improved durability. This process creates a denser, more robust piston that can withstand higher compression ratios and more aggressive tuning than cast pistons. The specific bore size is 4.125 inches, and the wrist pin diameter is 1.080 inches, ensuring it pairs correctly with compatible connecting rods and crankshafts for a precise fit within the cylinder.

Remember, this piston is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
