The KingTec Racing P1UZ forged piston set is engineered for performance tuning on the Toyota 1UZ-FE 4.0L V8 engine, commonly found in vehicles such as the Toyota Soarer, Toyota Crown, and Lexus LS400, SC400, and GS400.

The kit comes as a complete set of 8 pistons with pins and rings included. These components are intended for users performing internal engine upgrades to support increased horsepower. They are designed to match standard compression height and ratio specifications for the 1UZ-FE platform, ensuring compatibility with standard bore configurations of 87.5mm.
