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

If you're building a high-horsepower Toyota 3S-GTE engine, these Ultra Series pistons from JE Pistons are a solid choice. They're forged from 2618 aluminum, which is known for its strength and ability to handle extreme temperatures and pressures. This set is designed for a 3.386-inch bore and includes four pistons, ready to be installed in your 4-cylinder engine.

What sets these pistons apart is JE's proprietary Aligned Grain Flow forging technology. This process maximizes the metal's tensile strength, making them incredibly robust for high-boost applications. You also get custom-level features like a thermal barrier crown coating that reflects heat, helping to keep crown temperatures down and improve exhaust gas scavenging. The skirt coating reduces friction and wear on both the piston and cylinder walls, which also makes for quieter operation, especially when the engine is cold. Plus, they've got lateral gas ports to help maintain a strong ring seal even at high RPMs and under significant boost pressure.

These pistons come with high-strength wrist pins manufactured by Trend Performance, built to handle the demands of performance engines. They also feature optimized pin oiling to ensure everything stays well-lubricated, reducing heat and wear. Every feature on these Ultra Series pistons is geared towards high-horsepower performance, and they're made entirely in the USA. Keep in mind these are not CARB approved and cannot be shipped to California.
