Wiseco RED Series Ford Small Block 4.030in Bore 1.090in CH -5.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance applications. This RED Series piston set is built using their Race Engineered Design philosophy, meaning it's made for the demands of racing and power adder setups. These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them the tensile strength needed for serious performance engines, whether you're on the drag strip or the circle track.

You'll find some smart features on these pistons that make a real difference. The horizontal slot oiling in the pin bores is a key detail that keeps the wrist pin and small end of the connecting rod properly lubricated, which is crucial for a long service life under stress. Wiseco uses dedicated forgings for these pistons, allowing them to create an optimized, engine-specific strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, and it also cuts down on wear to the piston skirt and cylinder wall. This set comes complete with premium rings, so you won't need to source those separately.

An accumulator groove is also included to help maintain consistent ring seal and ensure you're getting maximum power from each cylinder. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning.
