Wiseco Chevy SB RED Series Piston Set 4060in Bore 1425in Compression Height 0927in Pin - Set of 8

Starting with a 2618 aluminum forging, these Wiseco RED Series pistons are built for the demands of performance racing and power adder applications. The RED (Race Engineered Design) series is specifically crafted to offer the strength and durability that high-output engines require, combined with precision machining for a competitive edge. These pistons are a cornerstone for anyone building a domestic V8 for serious performance, whether it's for drag racing or circle track competition.

Wiseco has incorporated several features to ensure longevity and optimal performance. The horizontal slot oiling in the pin bores is a critical detail that maintains proper lubrication for the wrist pin and the small end of the connecting rod, which is essential for long service life under stress. Dedicated forgings allow for an engine-specific strutted design, maximizing the strength-to-weight ratio. Additionally, the ArmorGlide skirt coating is applied to reduce operating friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. Each set comes complete with premium rings, so you don't have to source them separately, and an accumulator groove is included to help maintain consistent ring seal and power output.

This set includes eight pistons, each with a 4.060-inch bore, 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 where strength and reliability are paramount.
