Ford 4.6L/5.4L 2V Piston Set 3.572 Bore -1.6cc

The Ford 4.6L/5.4L 2V Piston Set 3.572 Bore -1.6cc by RACE TEC PISTONS is engineered for serious engine builders and performance enthusiasts targeting displacement and compression optimization in modular Ford applications. These pistons serve as drop-in replacements for factory units in two-valve 4.6L and 5.4L engines, making them ideal for street builds, mild boost applications, and naturally aspirated performance packages. Whether you're refreshing a tired engine or building a high-revving platform, this piston set delivers the geometry and material science needed to support reliable power gains.

Each piston in this set features a 3.572-inch bore diameter and a -1.6cc dome compression profile, which lowers effective compression ratio compared to flat-top designs—a critical consideration when adding boost or running on pump fuel in vintage or street-driven vehicles. The negative dome cavity reduces detonation risk while maintaining adequate quench clearance over the spark plug electrodes. RACE TEC PISTONS manufactures these components to OEM tolerances, ensuring proper ring seating, reduced blowby, and extended engine life. The low-compression design pairs well with forced induction systems or alternative fuel blends, giving builders flexibility in tuning strategy without sacrificing reliability or throttle response.

Mechanics and engine builders restoring 2004–2010 Ford Mustangs, F-150s, and Expedition platforms with 4.6L engines, as well as 2003–2010 Superduty trucks and newer Mustangs with 5.4L mills, will find this piston set compatible with factory blocks and cylinder heads when used with appropriate connecting rods and rings. Installation requires honing to exact bore specifications and careful piston-to-wall clearance verification. The complete 10-pound set covers a full engine, reducing the need for multiple sourcing trips and ensuring matched thermal expansion across all cylinders. For builders upgrading fuel systems, ignition timing, or adding turbo or supercharger hardware, this piston set provides the internal support needed to reach 400+ horsepower safely on the street.
