Wiseco RED Series Chevy LS 4.040in Bore 1.294in CH -15.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance applications. This RED Series piston set is built for Chevy LS engines and uses their Race Engineered Design (RED) philosophy to give you the strength and durability needed for demanding builds. Whether you're hitting the drag strip or the circle track, these pistons are designed to handle the stress of high-performance racing.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see a lot of power, especially with forced induction or other power adders. To help with lubrication and extend service life, they feature horizontal slot oiling in the pin bores, ensuring the wrist pin and small-end of the connecting rod stay well-lubricated. The dedicated forgings allow for an optimized, strutted design that balances strength with a low weight. Plus, each set comes with premium rings, so you won't have to hunt for compatible ones separately. An accumulator groove is also included to help maintain consistent ring seal and keep power output steady.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
