Wiseco Chevy SB RED Series Piston Set 4005in Bore 1425in Compression Height 0927in Pin - Set of 8

This is a set of eight Wiseco RED Series pistons, designed for Chevrolet Small Block engines. You get the pistons themselves, along with premium rings to get your engine rebuild started. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for the demands of performance racing and applications that use power adders like turbochargers or superchargers.

Wiseco's Race Engineered Design (RED) process means these pistons are built with specific features for a competitive edge. They use dedicated forgings, allowing for an engine-specific strutted design that balances strength with a low weight. The pin bores have horizontal slot oiling, which is a smart way to keep the wrist pin and the small end of the connecting rod properly lubricated, crucial for a long service life under stress. Additionally, each piston comes with an accumulator groove designed to help maintain consistent ring seal, which is key for keeping power levels stable.

To further reduce friction and noise, these pistons feature an ArmorGlide skirt coating. This coating also helps to minimize wear on both the piston skirt and the cylinder wall. This comprehensive package means you're getting a well-built set of pistons with features aimed at durability and performance for your engine build.
