Wiseco Chevy SB RED Series Piston Set 4000in Bore 1250in Compression Height 0927in Pin - Set of 8

Wiseco is well-known for making strong, reliable internal engine components for performance applications. Their RED? series pistons are built using Race Engineered Design? principles, meaning they offer the strength and durability that performance engines demand, along with precision-machined features to give you a competitive edge. These piston kits are available for a range of popular domestic V8 platforms, which are the backbone of racing from drag strips to circle tracks.

These pistons are forged and machined in the USA from 2618 aluminum, giving them the tensile strength needed for high-performance racing and applications with power adders. They feature horizontal slot oiling in the pin bores to keep the wrist pin and small-end of the connecting rod properly lubricated, which is crucial for a long service life. The dedicated forgings allow for an engine-specific, strutted design that maximizes strength while keeping weight down. An accumulator groove is included to help maintain consistent ring seal and power output. Plus, each set comes with premium rings, so you won't need to source those separately.

The pistons also have an ArmorGlide? skirt coating. This coating helps reduce operating friction and noise, while also minimizing wear on the piston skirt and cylinder wall. This is a comprehensive set designed for serious engine builds where reliability and performance are paramount.
