Wiseco RED Series Chevy LS 4.045in Bore 1.294in CH -15.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance Chevy LS engines. The RED (Race Engineered Design) series is all about combining the strength needed for racing and power adder applications with precision machining that gives you an edge. Whether you're building for drag racing or circle track, these pistons are a solid foundation.

Wiseco engineers these pistons with specific features to ensure longevity and performance. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and connecting rod small end properly lubricated under high stress. The dedicated forgings allow for an optimized, strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, lessening wear on both the piston skirt and the cylinder wall. Each set comes complete with premium rings, so you don't have to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set is designed for a 4.045-inch bore and features a 1.294-inch compression height, with a 0.927-inch pin diameter. Remember, these pistons are not CARB approved and cannot be shipped to California. They are sold as a set of 8.
