Wiseco RED Series Ford Small Block 4.040in Bore 1.090in CH -5.00 CC Piston Set

This Wiseco RED Series piston set gives you everything you need to rebuild the heart of your Ford Small Block engine. You get a complete set of eight forged pistons, each with a 4.040-inch bore and a 1.090-inch compression height. These pistons feature a -5.00cc dish, which is important for setting your desired compression ratio when paired with your cylinder heads and gasket thickness.

Wiseco builds these RED Series pistons using 2618 aluminum, a strong material chosen for its tensile strength, making them well-suited for performance racing and engines with power adders like turbos or superchargers. They've incorporated horizontal slot oiling in the pin bores to ensure the wrist pins and small-end of the connecting rods stay well-lubricated, which is key for long service life under demanding conditions. The dedicated forgings allow for an optimized, engine-specific strutted design that maximizes strength while keeping weight down. Plus, each set comes with premium rings, so you won't have to source those separately. An accumulator groove is also included to help maintain consistent ring seal and power output.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal results, always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
