Wiseco Chevy SB RED Series Piston Set 4005in Bore 1550in 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 Chevy Small Block engines that demand serious durability and precision. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard, especially with power adders like turbos or superchargers.

What sets these RED Series pistons apart is their Race Engineered Design. You get horizontal slot oiling in the pin bores, which is a smart way to make sure the wrist pin and the small end of the connecting rod stay well-lubricated, crucial for keeping things running smoothly over the long haul. The dedicated forgings mean Wiseco can optimize the strutted design for each specific engine, getting you the best possible strength-to-weight ratio. Plus, the ArmorGlide skirt coating is a nice touch; it cuts down on friction and noise, and it also helps reduce wear on both the piston skirt and the cylinder wall. You also get premium rings included with each set, so you don't have to hunt for compatible ones.

This set is designed for a 4.005-inch bore with a 1.550-inch compression height and a 0.927-inch pin diameter. An accumulator groove is also part of the design, helping to maintain consistent ring seal and keep power levels steady. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
