Wiseco Chevy SB RED Series Piston Set 4185in Bore 1425in Compression Height 0927in Pin - Set of 8

If you're building a performance Chevy Small Block engine, this Wiseco RED Series piston set is designed to handle the demands of racing and power adder applications. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see high RPMs and significant stress. The RED series, standing for Race Engineered Design, means these pistons have specific features aimed at giving you a competitive edge on the track or strip.

Wiseco machines these pistons in the USA, and they come with several well-built features to ensure longevity and performance. The horizontal slot oiling in the pin bores keeps the wrist pin and connecting rod small end properly lubricated, which is vital for preventing wear. Dedicated forgings are used to create an engine-specific strutted design, balancing strength with a low weight. Each set also includes premium rings, so you won't need to source those separately, and an accumulator groove is incorporated to help maintain consistent ring seal and power delivery under pressure.

This set is for a 4.185 inch bore with a 1.425 inch compression height and a 0.927 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance applications and are a solid option for serious engine builds.
