Wiseco Chevrolet LS -4cc Flat Top 1.294 X 4.145 - Set of 8

Wiseco is well-known for making strong, reliable engine components for performance applications. This RED Series piston set is built specifically for Chevrolet LS engines, offering the strength and precision needed for demanding builds. These aren't your average pistons; they're designed with Race Engineered Design (RED) principles to give you a competitive edge whether you're on the drag strip or the circle track.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for high-performance racing and engines with power adders. To ensure optimal lubrication and longevity, the pin bores feature horizontal slot oiling, keeping the wrist pin and small-end of the connecting rod well-lubricated. The dedicated forgings allow for an engine-specific strutted design, balancing maximum strength with a low weight. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall.

This set comes complete with premium rings, so you won't need to source them separately. An accumulator groove is also included to help maintain consistent ring seal and power delivery. Please note that these pistons are not CARB approved and cannot be shipped to California.
