IRP forged pistons / rods, FORD 2.3LTR. ECO BOOST (Focus RS, Focus ST, Mustang..)

Italian RP (IRP) Forged Pistons & Connecting Rods kit

Forged pistons and high-performance connecting rods, engineered for high-load applications such as Stage 3 builds and dedicated racing use. The components replace OEM parts to improve reliability under sustained boost, heat, and high RPM. Sets are available in multiple bore sizes and compression ratios (selectable from the variant menu). By default, this product is supplied as a combined pistons+rods kit, but a pistons-only option is also available from the drop-down menu if preferred.

By upgrading to forged pistons and rods, enthusiasts gain a solid foundation for tuning beyond stock limits. These components are designed to handle increased cylinder pressures and provide long-term reliability in both street and track builds.

What’s included

• Forged piston set with pins, locks, and rings
• Forged H-beam connecting rod set
• Rod bolts: VIMI2500 (standard). L19 or Custom Age upgrades available separately (see Related Products).

Kit levels
