Wiseco RED Series Ford Small Block 4.000in Bore 1.165in CH -15.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance applications. This RED Series piston set is built for Ford Small Block engines and uses their Race Engineered Design (RED) philosophy to give you a competitive edge. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them the tensile strength needed for serious racing and engines with power adders like turbos or superchargers.

You'll find some smart details on these pistons that make a real difference. The horizontal slot oiling in the pin bores keeps the wrist pin and small end of the connecting rod well-lubricated, which is key for a long service life under stress. Wiseco uses dedicated forgings for each engine application, allowing them to create a strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also cutting down on wear on the piston skirt and cylinder walls. An accumulator groove is included to help maintain consistent ring seal and power delivery.

This set includes premium rings, so you won't need to source those separately. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Ford Small Block, this set is a solid option for the core of your engine.
