Wiseco RED Series Chevy LS 4.130in Bore 1.105in CH -20.00 CC Piston Set

If you're building a high-performance Chevy LS engine for serious racing, the Wiseco RED Series pistons are designed to handle the stress. These aren't your average replacement pistons; they're forged from 2618 aluminum, a material chosen for its tensile strength, which is crucial when you're pushing an engine hard, whether that's on the drag strip or the circle track. The Race Engineered Design, or RED, means these pistons are specifically shaped to give you a competitive edge.

Wiseco machines these pistons in the USA with features that matter for longevity and performance. You'll find horizontal slot oiling in the pin bores to keep the wrist pins and connecting rod small ends well-lubricated, which is key for preventing premature wear. The dedicated forgings allow for an optimized, engine-specific strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the skirts and cylinder walls. This set comes complete with premium rings, so you won't need to hunt for those separately.

An accumulator groove is also included to help maintain consistent ring seal, which directly translates to consistent power delivery. These pistons are built for power adder applications and demanding performance builds where reliability under extreme conditions is a must. Please note that these are not CARB approved and cannot be shipped to California.
