Wiseco RED Series Chevy LS 4.045in Bore 1.105in CH -20.00 CC Piston Set

Starting with a 2618 aluminum forging, these Wiseco RED Series pistons are built for the demands of high-performance Chevy LS engines. The Race Engineered Design (RED) process means they're not just strong, but also precisely machined to give you an edge, whether you're on the drag strip or the circle track. These are a popular choice for serious engine builds where durability and consistent performance are key.

You'll find features like horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and connecting rod small end well-lubricated, helping to ensure a long service life for your engine. The dedicated forgings allow for a strutted design that maximizes strength while keeping weight down, a smart balance for performance applications. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the piston skirt and cylinder walls.

This set comes complete with premium rings, so you won't need to source those separately. An accumulator groove is also included, which helps maintain a consistent seal for the piston rings, contributing to steady power output. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
