Wiseco RED Series Chevrolet Small Block 4.165in Bore 1.550in CH -1.00 CC Piston Set

Wiseco's RED Series pistons are built for Chevrolet Small Block engines that demand serious strength and durability. These pistons use Race Engineered Design (RED) principles, meaning they're forged and machined in the USA from 2618 aluminum to handle the rigors of racing and power adder applications. If you're building a performance engine for drag racing or circle track, these pistons are a solid foundation.

You'll find some well-thought-out features here. The horizontal slot oiling in the pin bores helps keep the wrist pin and small end of the connecting rod properly lubricated, which is crucial for long service life under high stress. Wiseco uses dedicated forgings for each engine application, allowing them to optimize the strutted design for the best possible strength-to-weight ratio. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also cutting down on skirt and cylinder wear. This set comes complete with premium rings, so you won't need to source those separately.

An accumulator groove is also included to help maintain consistent ring seal and power delivery. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're looking for a well-built, performance-focused piston set for your Chevrolet Small Block, this Wiseco RED Series set is a strong contender.
