JE Pistons Honda K-Series 87.5mm Bore 10.0:1 CR 1.176 CD Dome Piston Kit - Set of 4

Forged in the USA from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is specifically designed for Honda K-Series engines, featuring an 87.5mm bore and a 10.0:1 compression ratio with a 1.176" compression distance. The 2618 aluminum alloy provides the high tensile strength needed to withstand the rigors of performance tuning and racing.

JE Pistons incorporates their proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by using a reduced skirt width. This design also saves weight by utilizing a shorter wrist pin. Depending on the specific application, an accumulator groove may be included to reduce combustion gas pressure, which helps prevent ring flutter and improves ring seal for more consistent power delivery. Some applications also feature a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This kit includes four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings, making it a complete package for rebuilding or upgrading your K-Series engine. These pistons are engineered for each specific engine and use application to offer an optimized combination of performance and durability, proven time and again in racing environments.
