Wiseco Chevy SB RED Series Piston Set 4130in Bore 112in Compression Height 0927in Pin - Set of 8

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

The Race Engineered Design (RED) philosophy behind these pistons means they're not just strong, but also precisely machined to give you an edge. You'll find horizontal slot oiling in the pin bores, which is a smart feature that keeps the wrist pin and the small end of the connecting rod well-lubricated, helping to ensure a long service life even under extreme conditions. The dedicated forgings allow for an engine-specific strutted design, meaning Wiseco has optimized the strength-to-weight ratio for this particular application. Plus, the ArmorGlide skirt coating is a notable detail that works to reduce friction and noise, while also cutting down on wear on both the piston skirt and the cylinder wall. Each set comes complete with premium rings, so you won't have to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power output.

This set is designed for a 4.130-inch bore with a 1.125-inch compression height and a 0.927-inch pin diameter. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a performance Chevy SB, these pistons offer a well-built foundation for serious power.
