Wiseco Chevy SB RED Series Piston Set 4125in Bore 1000in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine for racing, the Wiseco RED Series pistons are a solid choice. These pistons are forged from 2618 aluminum, a material known for its tensile strength, making them well-suited for the demands of racing and boosted applications. They are designed to give you a competitive edge on the track, whether you're competing in drag racing or circle track events.

Wiseco's Race Engineered Design (RED) process means these pistons are not only strong but also precisely machined. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and small end of the connecting rod properly lubricated, extending their service life. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a low weight. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls. This set comes complete with premium rings, so you won't need to source them separately, and an accumulator groove is included to help maintain consistent ring seal and power output.

This set includes eight pistons, all with a 4.125-inch bore, a 1.000-inch compression height, and a 0.927-inch pin diameter. Please note that 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 procedures.
