Wiseco RED Series Chevrolet Small Block 4.155in Bore 1.550in CH -1.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance applications. This RED Series piston set is built for Chevrolet Small Block engines and uses their Race Engineered Design (RED) philosophy to give you the strength and durability needed for demanding racing and power adder setups. These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, making it ideal for the stresses of performance racing.

You'll find features like horizontal slot oiling in the pin bores, which is a smart way to keep the wrist pin and small-end of the connecting rod properly lubricated, helping to ensure a long service life even under heavy use. The dedicated forgings allow for an engine-specific strutted design, meaning Wiseco has optimized the shape to give you the best possible strength-to-weight ratio. Plus, each set comes with premium rings, so you won't have to hunt for those separately. The accumulator groove is another detail that helps maintain consistent ring seal and power delivery.

This set is designed for a 4.155 inch bore and has a compression height of 1.550 inches, with a -1.00 CC dish. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevrolet Small Block, these pistons are a solid option for serious power.
