Wiseco RED Series Ford Small Block 4.020in Bore 1.230in CH -5.00 CC Piston Set

Starting with the 2618 aluminum construction, these Wiseco RED Series pistons are built for the demands of performance racing and power adder applications. The RED? series, which stands for Race Engineered Design?, means these pistons are precision-machined to give you a competitive edge, whether you're on the drag strip or the circle track. They are forged and machined right here in the USA, ensuring a well-built component for your engine.

You'll find horizontal slot oiling in the pin bores, a detail that's crucial for keeping the wrist pin and small-end of the connecting rod properly lubricated. This helps ensure a long service life, even under high stress. Wiseco uses dedicated forgings for each engine application, allowing for an optimized strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the piston skirt and cylinder walls. This set includes premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set is designed for Ford Small Block engines with a 4.020-inch bore and features a 1.230-inch compression height with a -5.00cc dish. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
