Wiseco RED Series Chevrolet Small Block 4.185in Bore 1.125in CH -7.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of high-performance Chevrolet Small Block engines. The RED (Race Engineered Design) series is all about giving you the strength and durability needed for serious racing and power adder applications, with precision features that help you get the most out of your build. Whether you're hitting the drag strip or the circle track, these pistons are a solid foundation for a powerful engine.

Each piston in this set features horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pin and small-end of the connecting rod well-lubricated. This is critical for ensuring a long service life, especially under high stress. Wiseco also uses dedicated forgings for each engine application, allowing them to create an optimized strutted design that maximizes strength while keeping weight down. You'll also find an ArmorGlide skirt coating, which works to reduce friction and noise, while also cutting down on wear on both the piston skirt and the cylinder wall. This set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set is designed for a 4.185-inch bore with a 1.125-inch compression height and includes a 0.927-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
