Wiseco RED Series Chevrolet Small Block 4.185in Bore 1.550in CH -1.00 CC Piston Set

If you're building a high-performance Chevrolet Small Block engine, Wiseco's RED Series pistons are a solid option. These pistons are forged from 2618 aluminum, a material chosen for its tensile strength, which is crucial for handling the demands of racing and boosted applications. The RED Series stands for Race Engineered Design, meaning they're built with precision-machined features to give you a competitive edge on the track or strip.

Wiseco machines these pistons in the USA, and they come with several thoughtful details. The horizontal slot oiling in the pin bores helps keep the wrist pin and small-end of the connecting rod properly lubricated, which is key for a long service life. Dedicated forgings are used to create an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an ArmorGlide skirt coating that works to reduce friction and noise, while also cutting down on skirt and cylinder wear. Plus, each set includes premium rings, so you won't need to source those separately, and an accumulator groove helps maintain consistent ring seal and power delivery.

This set is designed for a 4.185-inch bore with a 1.550-inch compression height and a -1.00 CC valve relief. It's important to note that these pistons are not CARB approved and cannot be shipped to California. They are intended for off-road use and performance applications where durability and precise engineering are paramount.
