JE Pistons ACURA K20 10:1 KIT Set of 4 Pistons

Starting with a 2618 aluminum forging, these JE Pistons are built for serious performance in your 2006-2013 Chevrolet Corvette. This kit includes four pistons, each designed with a specific dome shape to achieve a 10.00:1 compression ratio, which is a notable bump over stock for improved power output. JE Pistons has been making forged pistons for over 75 years, and they machine these entirely in the USA to ensure they meet strict quality standards for durability and performance.

You'll find JE's proprietary Forged Side Relief (FSR) design on these pistons. This means they have reduced skirt width and a shorter wrist pin, which helps minimize friction and power loss while also saving weight. Depending on the specific application, these pistons might also feature an accumulator groove to help control combustion gas pressure, reducing ring flutter and improving the seal for consistent power delivery. Some applications also include a skirt coating to further reduce friction and wear on the cylinder walls, which can also lead to quieter operation.

This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components needed for installation. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
