Wiseco RED Series Chevy Small Block 350 4.020in Bore 1.125in CH -17.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance racing and power adder applications. The Race Engineered Design (RED) process means they're not just strong, but also precisely machined to give you an edge. They're a popular choice for everything from drag racing to circle track, forming the foundation for many high-performance domestic V8 engines.

You'll find horizontal slot oiling in the pin bores, which is crucial for keeping the wrist pin and small end of the connecting rod well-lubricated, contributing to a longer service life. Wiseco uses dedicated forgings for each specific engine, allowing them to create an optimized, strutted design that maximizes strength while keeping weight down. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. Each set comes complete with premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power output.

These pistons are designed for a 4.020-inch bore with a 1.125-inch compression height and a -17.00cc dish volume. Please note that these are not CARB approved and cannot be shipped to California.
