Wiseco RED Series Chevy LS 4.010in Bore 1.105in CH -20.00 CC Piston Set

Starting with dedicated forgings from 2618 aluminum, Wiseco's RED Series pistons are built for the demands of performance racing and power adder applications. These pistons are engineered and machined in the USA, featuring a Race Engineered Design (RED) to give you a competitive edge. The 4.010-inch bore size is specific for many Chevrolet LS engines, and the -20.00 CC dish helps achieve your desired compression ratio.

Wiseco has incorporated several features to ensure durability and performance. Horizontal slot oiling in the pin bores keeps the wrist pin and small-end of the connecting rod properly lubricated, which is crucial for a long service life under stress. An accumulator groove is included to help maintain consistent ring seal and power output. The ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall.

This set includes eight pistons, each designed with an optimized, engine-specific strutted design to maximize strength while keeping weight down. Premium rings are included with each set, so you won't need to source them separately. Please note that these pistons are not CARB approved and cannot be shipped to California.
