Wiseco RED Series Chevrolet Big Block 4.530in Bore 1.155in CH 15.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for racing, like drag or circle track, you need pistons that can handle serious stress. The Wiseco RED Series pistons are built for exactly that. They use Race Engineered Design (RED) principles to give you the strength and durability required for demanding applications, along with precision machining for a competitive edge.

These pistons are forged and machined right here in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for racing and engines with power adders. Wiseco includes a lot of thoughtful details to ensure longevity and performance. For instance, the horizontal slot oiling in the pin bores keeps the wrist pin and small-end of the connecting rod properly lubricated, which is crucial for long service life. The dedicated forgings are designed specifically for each engine application, creating a strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirt and 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 4.530-inch bore with a 1.155-inch compression height and a 0.990-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
