Wiseco RED Series Chevy LS 4.135in Bore 1.105in CH -10.00 CC Piston Set

These Wiseco RED Series pistons start with a 2618 aluminum forging, chosen for the high tensile strength needed in performance racing and power adder applications. The RED (Race Engineered Design) series is built to give your Chevy LS engine the durability and precision it needs to compete, whether you're on the drag strip or the circle track.

Wiseco machines these pistons in the USA, incorporating features like horizontal slot oiling in the pin bores. This design detail is crucial for keeping the wrist pin and the small end of the connecting rod properly lubricated, which directly impacts the longevity of your engine's internals. The dedicated forgings are shaped into an engine-specific strutted design, balancing strength with a low weight for better overall performance. Each set also comes with an ArmorGlide skirt coating that works to reduce friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. An accumulator groove is included to help maintain consistent ring seal and power delivery.

This set includes premium rings, so you won't need to source those separately. Please note that these pistons are not CARB approved and cannot be shipped to California.
