Wiseco RED Series Chevrolet Small Block 4.165in Bore 1.062in CH -9.00 CC Piston Set

If you're building a performance Chevrolet Small Block engine, this set of Wiseco RED Series pistons is a solid choice. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is essential for the demands of racing and engines with power adders like turbochargers or superchargers. The RED series stands for Race Engineered Design, meaning Wiseco has focused on features that give you a competitive edge on the track or strip.

Wiseco has incorporated several thoughtful details into these pistons. The horizontal slot oiling in the pin bores is a critical feature that ensures consistent lubrication for the wrist pin and the connecting rod's small end, which helps extend the life of these high-stress components. Each piston uses a dedicated forging, allowing Wiseco to optimize the strutted design for maximum strength while keeping the weight down. You'll also find an accumulator groove, which helps maintain a consistent ring seal, ensuring you get the most power out of every combustion cycle. Plus, 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 set includes premium rings, so you won't need to source those separately, making your build process smoother. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for a 4.165-inch bore with a 1.062-inch compression height and a -9.00cc dish volume.
