Specifically engineered for blocks bored to 76mm. This 76mm hypereutectic piston, crafted from the same high-silicon alloy used in the proven Tillotson 72mm Racing Piston—now scaled up for big displacement performance without sacrificing strength or budget.

The 76mm piston delivers increased displacement—3" bore—for serious power gains. Despite its larger size, the piston assembly weighs just 195g, making it lighter than many smaller-diameter pistons on the market. Less weight means better balance, quicker acceleration, and improved durability under high-RPM loads.

The 13mm wrist pin is longer and the journal wider than the 72mm version, adding structural integrity while supporting high-performance builds. The shorter compression height of .715" (vs. .765") allows for longer billet rods like the 8282 Pinnacle Rod, optimized for use with a 58mm crankshaft to create a true 263cc engine.
