JE Pistons 97-05 Toyota 3S-GE BEAMS CR 12.5:1 Bore 86.5 Stroke 86mm Dome 1.1cc Piston Set(4) w.Rings

Forged in the USA using 2618 aluminum, these JE Pistons are built for high-demand performance applications like your 3S-GE BEAMS engine. With a 12.5:1 compression ratio, they're designed to help you extract maximum power from your build, whether it's for track days or spirited street driving. JE Pistons brings over 75 years of experience to the table, ensuring you get a well-built component that's engineered specifically for your engine.

These pistons feature JE's proprietary Forged Side Relief (FSR) design, which uses a reduced skirt width and a shorter wrist pin to minimize friction and power loss, while also saving weight. Depending on the specific application, they may also include an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

This set includes four pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings, giving you a complete package to get your engine rebuilt. Remember that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
