Wiseco RED Series Chevy LS 4.165in Bore 1.105in CH -20.00 CC Piston Set

If you're building a performance Chevy LS engine, this Wiseco RED Series piston set is designed to handle the demands of racing and power adder applications. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard. The RED series stands for Race Engineered Design, meaning Wiseco has put a lot of thought into making these pistons strong and precise for competitive use.

Wiseco machines these pistons in the USA, and they've included some smart features to help your engine run better and last longer. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pin and connecting rod small end well-lubricated, a key factor for durability. The dedicated forgings allow for an optimized strutted design, balancing strength with a manageable weight. Plus, each set comes with premium rings, so you don't have to hunt for compatible ones separately. An accumulator groove is also included to help maintain a consistent ring seal, which means more consistent power delivery.

These pistons also feature an ArmorGlide skirt coating. This isn't just for looks; it's there to reduce friction and noise from the piston skirts against the cylinder walls, which also helps cut down on wear. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are intended for off-road or racing use where emissions regulations may differ.
