JE Pistons Toyota 3S-GE 3.396 Bore 12.5:1 CR (Set of 4)

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications, offering the tensile strength needed for serious engine builds. This set is specifically designed for the Toyota 3S-GE BEAMS engine, featuring a 3.396-inch bore and a 12.5:1 compression ratio. JE Pistons brings over 75 years of experience to the table, with every piston engineered, forged, and machined in the USA to deliver a combination of durability and performance proven on the track.

This piston set includes JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin for added weight savings. Depending on the specific application, an accumulator groove may be included to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power output. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation. This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have everything needed for a proper installation.

When rebuilding or modifying your 3S-GE engine for performance, these pistons are a solid option. They are designed specifically for the engine and intended use, aiming for optimized performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California.
