Wiseco RED Series Chevrolet Small Block 4.185in Bore 1.250in CH -1.00 CC Piston Set

If you're rebuilding a performance Chevrolet Small Block engine, Wiseco's RED Series pistons are built to handle the demands of racing and high-power applications. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for the stresses of drag racing, circle track, and engines with power adders. The Race Engineered Design (RED) process ensures these pistons are precisely machined for optimal performance and durability.

Wiseco engineers these pistons with specific features to enhance longevity and power delivery. 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 under high loads. The dedicated forgings allow for an engine-specific, strutted design that maximizes strength while keeping weight down. Additionally, each set comes complete with premium rings, so you won't need to source those separately. The accumulator groove is also included to help maintain consistent ring seal and sustained power output.

This set is designed for a 4.185-inch bore with a 1.250-inch compression height and a -1.00cc volume dish. Please note that these pistons are not CARB approved and cannot be shipped to California.
