Product Description

The Wiseco K550M865AP is a professional-grade forged piston kit engineered specifically for Toyota's 2JZ-GTE 3.0 L twin-turbo engine. Built from 2618 aluminum, these pistons provide excellent strength and resistance to high RPM and boost-induced stress.

Its -14.8 cc dished crown helps lower compression to around ~8.4:1, making it well-suited for high-boost tuning while maintaining detonation safety. The ArmorGlide® coated skirts reduce friction and wear, and forced pin oiling ensures consistent lubrication under severe duty.

This complete kit comes with the pistons, 22 mm wrist pins, circlips, and a premium 8650XX ring set - everything required for a full 6-cylinder engine build. Whether you're building a race car, a high-power street machine, or a tuned 2JZ-GTE for serious performance, the K550M865AP delivers strength, precision, and reliability.
