JE Pistons Ferrari 330 4.0L V12 77.50mm Bore - Set of 2

If you're rebuilding the heart of your Ferrari 330 with the 4.0L V12 engine, these JE Pistons are a solid choice. This set includes two pistons, each with a 77.50mm bore and designed for a 10.00:1 compression ratio, specifically tailored for your V12 application.

JE Pistons has been in the forged piston game for over 75 years, and they build these right here in the USA from 2618 aluminum. This material gives them the strong tensile strength needed for high-demand performance builds. They use a proprietary Forged Side Relief (FSR) design which helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons might also feature an accumulator groove to help manage combustion gas pressure, improving ring seal and preventing flutter. Some applications also include a skirt coating to further reduce friction and wear on the cylinder walls, which also helps quiet down the engine operation.

This kit comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have the essential components to get your engine back together. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
