JE Pistons Toyota 3SGTE Ultra Series - Set of 4 Pistons

If you're building a high-performance Toyota 3S-GTE engine, especially one that will see significant boost, a strong set of pistons is crucial. These Ultra Series pistons from JE Pistons are designed to handle the extreme cylinder pressures that come with power-adder builds. They are a set of four, ready to replace your stock pistons and form the foundation of a robust engine.

What sets these pistons apart is JE's proprietary Aligned Grain Flow forging technology. This process maximizes the material's tensile strength, making them incredibly strong for demanding engine environments. You also get custom-level features usually found only in fully custom builds. The thermal barrier crown coating helps reflect heat back into the combustion chamber, which can improve exhaust scavenging and keep piston crown temperatures in check. For reduced friction and wear, the skirts are coated, and these coatings also help quiet down the engine, especially during cold starts. Lateral gas ports are included to help maintain a solid seal on the top compression ring, even under high RPM and high boost conditions, which is vital for consistent power production. These pistons are built with high-strength wrist pins from Trend Performance, designed to handle the rigors of performance builds. Every feature is optimized for high-horsepower racing engines, and importantly, they are made 100% in the USA.

This set includes four pistons, each with a 3.406-inch bore and an inverted dome/dish design, aiming for a 9.00:1 compression ratio. They come with 0.866-inch pins. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're pushing the limits of your 3S-GTE, these pistons offer a well-built, feature-rich solution.
