JE Pistons Toyota 4A-GE 20V 82mm Bore (Size +1.0mm) 11.5:1 CR 6.1cc Dome Piston (Set of 4)

If you're rebuilding the engine for your Toyota 4A-GE 20V, these JE Pistons are a solid choice for serious performance. This set includes four pistons, each measuring 82mm in bore size with a +1.0mm overbore, designed to achieve an 11.5:1 compression ratio with a 6.1cc dome volume. JE Pistons brings over 75 years of experience to the table, engineering and manufacturing these pistons entirely in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for high-demand applications.

These pistons feature JE's proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, you might find an accumulator groove, which works to reduce pressure from combustion gases, helping to prevent ring flutter and improve ring seal for more consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation. This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have the essential components for a proper installation.

Because these pistons are specifically designed for the 4A-GE 20V engine, they are optimized for performance and durability. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance on fitting these pistons to your engine.
