JE Pistons PORSCHE 3.0L DM KIT Set of 6 Pistons

JE Pistons is known for making strong, reliable forged pistons that have proven themselves on the track for over 75 years. If you're rebuilding the air-cooled 6-cylinder engine in your 1978-1983 Porsche 911, this 3.0L DM KIT piston set is built to handle the demands of performance driving.

These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for high-demand engine applications. JE Pistons engineers each set specifically for the engine and intended use, aiming for the best balance of durability and performance. This kit includes everything you need to get your engine back together: the six pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. The pistons feature a dome design for a 10.50:1 compression ratio and a 3.740-inch bore size, with a 1.335-inch compression distance and a 0.866-inch pin diameter.

Features like the proprietary Forged Side Relief (FSR) design help minimize friction and weight, while an accumulator groove can help reduce combustion gas pressure for better ring seal. Some applications may also include a skirt coating to further reduce friction, wear, and noise. This is a complete set designed to give your Porsche 911 engine a solid foundation for power and longevity.
