JE Pistons Forged Piston Kit – Gen 3 HEMI 6.4L Apache, 4.100" Bore (Set of 8)
The JE Pistons Forged Piston Kit is a premium set of eight forged pistons engineered specifically for the Gen 3 HEMI 6.4L Apache engine. Forged from high-strength 2618 aluminum in the USA, these pistons deliver the durability and performance required for high-horsepower naturally aspirated or boosted applications.
The kit features a dish design with a -5.20cc volume, 1.210" compression height, and 0.927" wrist pin diameter. Proprietary Forged Side Relief (FSR) design reduces skirt width and friction while allowing the use of a shorter, lighter wrist pin. Accumulator grooves help control ring flutter, and the pistons are coated on the skirts (where applicable) to reduce wear and noise.
This set does not include rings or wrist pins, allowing you to choose the exact components for your build. Ideal for street, track, or heavily modified 6.4L Apache HEMI engines.
