JE Pistons Honda B18C1/C2/C3/C4 83mm Bore 8.2cc Dome 12:5:1 CR Kit - Set of 4 Pistons

Starting with a 2618 aluminum forging, these JE Pistons are built for serious performance in your Honda B18C1, C2, C3, or C4 engine. This set is designed for an 83mm bore and features a dome shape that results in a 12.5:1 compression ratio, giving you a notable bump in power potential. JE Pistons has been making forged pistons for over 75 years, and they engineer and machine these right here in the USA to handle the stresses of high-demand applications.

The design incorporates JE's proprietary Forged Side Relief (FSR) forging, which uses a reduced skirt width and a shorter wrist pin. This not only saves weight but also helps minimize friction and power loss. Depending on the specific application, you might also find an accumulator groove, which helps control combustion gas pressure to prevent ring flutter and maintain a consistent ring seal. Some applications also include a skirt coating to further reduce friction and wear on the cylinder walls, leading to quieter operation and longer life.

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