Wiseco Chevy SB RED Series Piston Set 4185in Bore 1550in Compression Height 0927in Pin - Set of 8

Forged from 2618 aluminum, 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?, offers a strong foundation for engines used in everything from drag racing to circle track. Each piston is meticulously machined in the USA to ensure it meets the high standards required for competitive performance.

Wiseco has incorporated several thoughtful features to enhance durability and performance. Horizontal slot oiling in the pin bores is crucial for keeping the wrist pin and small-end of the connecting rod properly lubricated, which directly contributes to a longer service life. The dedicated forgings allow for an engine-specific, strutted design that maximizes strength while keeping weight down. Additionally, an accumulator groove is included to help maintain consistent ring seal and power output under stress. The ArmorGlide skirt coating is a notable touch, working to reduce operating friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall.

This set comes complete with premium rings, so you won't need to source those separately. This comprehensive approach ensures you have a well-matched set of components ready for installation. Please note that these pistons are not CARB approved and cannot be shipped to California.
