Wiseco RED Series Chevy LS 4.035in Bore 1.105in CH -20.00 CC Piston Set

Forged from 2618 aluminum, 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. This set is designed for a 4.035-inch bore with a 1.105-inch compression height and a -20.00cc dish, making them a solid choice for rebuilding or upgrading your LS power plant.

Wiseco uses dedicated forgings for each engine application, allowing them to optimize the strutted design for maximum strength while keeping weight down. You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pins and small-end of the connecting rods properly lubricated for a long service life. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the skirts 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 to help maintain consistent ring seal and ensure you're getting the most power out of every combustion cycle. These pistons are engineered and machined in the USA, reflecting Wiseco's commitment to quality for performance racing and power adder applications. Please note that these are not CARB approved and cannot be shipped to California.
