Wiseco RED Series Chevy LS 4.165in Bore 1.294in CH -15.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of high-performance racing and power adder applications. The Race Engineered Design (RED) philosophy means these pistons offer the strength you need for serious engine builds, combined with precision machining for a competitive edge. They are specifically designed for popular domestic V8 platforms, making them a cornerstone for everything from drag racing to circle track competition.

Wiseco incorporates several thoughtful features to ensure longevity and performance. Horizontal slot oiling in the pin bores keeps the wrist pin and connecting rod small end properly lubricated, which is crucial for extended service life under stress. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an ArmorGlide skirt coating, which works to reduce friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. An accumulator groove is included to help maintain consistent ring seal and power delivery.

This set includes premium rings, so you won't need to source them separately. 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 anyone rebuilding a Chevy LS engine for serious use.
