Wiseco Chevy SB RED Series Piston Set 4130in Bore 1215in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine, this Wiseco RED Series piston set is designed to handle the demands of racing and power adder applications. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see extreme stress from drag racing, circle track, or forced induction. Wiseco's Race Engineered Design (RED) process ensures these pistons are precisely machined for optimal performance and durability.

Each piston in this set features a horizontal slot oiling system in the pin bores. This design helps maintain consistent lubrication for the wrist pin and the connecting rod's small end, which is vital for preventing premature wear and ensuring a long service life under high loads. The dedicated forgings allow for an engine-specific, strutted design that maximizes the strength-to-weight ratio, meaning you get robust pistons without unnecessary mass. Additionally, the ArmorGlide skirt coating is applied to reduce friction and noise during operation, while also minimizing wear on the piston skirt and cylinder wall. This coating contributes to a smoother running engine and extends the life of your components.

This set includes premium rings, so you won't need to source them separately, simplifying your build process. An accumulator groove is also incorporated into the piston design to help maintain consistent ring seal, which is essential for maximizing compression and power output. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance applications where strength and precision are paramount.
