Wiseco RED Series Ford Small Block 4.030in Bore 1.090in CH -5.00 CC Piston Set

If you're building a performance Ford Small Block engine, especially one that will see heavy use like drag racing or circle track, you need pistons that can handle the stress. The Wiseco RED Series pistons are built for exactly that kind of demanding application. They use Race Engineered Design (RED) principles to give you the strength and durability needed for high-horsepower builds and power adder setups.

These pistons are forged and machined right here in the USA from 2618 aluminum, a material known for its tensile strength, which is crucial when you're pushing an engine hard. Wiseco also includes some smart features to help them last. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pins and the small end of the connecting rods well-lubricated. The dedicated forgings mean they're optimized for specific engines, giving you a strong yet lightweight piston. Plus, the ArmorGlide skirt coating helps cut down on friction and noise, while also reducing wear on the skirts and cylinder walls. Each set comes complete with premium rings, so you don't have to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set is for an 8-cylinder engine with a 4.030-inch bore and a -5.00cc dish, giving you a specific compression ratio target. Keep in mind these are not CARB approved and cannot be shipped to California. For a serious performance build, these pistons offer a well-built foundation.
