Wiseco Chevy SB RED Series Piston Set 4185in Bore 1250in Compression Height 0927in Pin - Set of 8

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This RED Series piston set is built for Chevrolet Small Block engines, designed to handle the demands of racing and high-horsepower builds. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its excellent tensile strength, which is crucial when you're pushing an engine hard, especially with power adders like turbochargers or superchargers.

The Race Engineered Design (RED) philosophy behind these pistons means they're not just strong, but also precisely machined for a competitive edge. You'll find horizontal slot oiling in the pin bores, which is a smart feature that keeps the wrist pin and small-end of the connecting rod well-lubricated, helping to ensure a long service life even under heavy use. The dedicated forgings allow for an optimized, engine-specific strutted design, which means Wiseco engineers were able to maximize strength while keeping the weight down. Plus, each set comes with premium rings already included, so you don't have to hunt for compatible ones. The ArmorGlide skirt coating is another notable detail, working to reduce friction and noise while also cutting down on wear to the piston skirt and cylinder wall.

An accumulator groove is also part of the design, helping to maintain consistent ring seal and keep power levels steady. If you're building a performance Chevy SB engine for drag racing, circle track, or any application where durability and precise performance are key, this set is a solid option. Please note that these pistons are not CARB approved and cannot be shipped to California.
