Wiseco Chevy LS 4.185in Bore 1.165in CH -12.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of severe duty race applications. The 4.185-inch bore size and 1.165-inch compression height, combined with a -12.00cc dish volume, are specific choices for builders aiming for high-performance LS engine builds. Wiseco machines these pistons in the USA, ensuring precise tolerances for critical components like the ring grooves, which feature anti-detonation designs and additional sealing features to improve overall ring seal. This attention to detail helps maintain cylinder pressure and efficiency under extreme conditions.

Beyond the core construction, these pistons include an ArmorGlide skirt coating. This specialized coating is designed to reduce friction, resist seizure, and contribute to quieter operation, all of which are important factors when building a high-output engine that needs to perform reliably. The crown is also fully machined, and the design incorporates forced pin oiling to ensure the wrist pin receives adequate lubrication, a crucial element for longevity in racing engines. This set includes eight pistons, ready for your next serious engine project.

Please 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.
