Wiseco RED Series Chevrolet Small Block 4.135in Bore 1.425in CH -7.00 CC Piston Set

If you're building a high-performance Chevrolet Small Block engine for racing, the Wiseco RED Series pistons are designed to give you a serious competitive edge. These aren't your average replacement pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for handling the extreme demands of racing and boosted applications. Wiseco's Race Engineered Design (RED) philosophy means these pistons are meticulously crafted in the USA to offer both the brute strength needed for power adders and the precision machining that performance engines require.

You'll find some smart details here that make a real difference. The horizontal slot oiling in the pin bores is a key feature for keeping the wrist pin and small-end of the connecting rod properly lubricated, which is vital for the long service life of your engine, especially under heavy use. Wiseco uses dedicated forgings for each specific engine application, allowing them to create an optimized, strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating is a notable addition that works to reduce friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. This set comes complete with premium rings, so you won't need to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

When you're pushing an engine hard, every component matters. These RED Series pistons are a well-built choice for drag racing, circle track, or any application where durability and performance are paramount. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
