Wiseco RED Series Chevy Small Block 350 4.000in Bore 1.425in CH -9.00 CC Piston Set

When you're building a performance Chevy Small Block 350, you need parts that can handle the stress. This Wiseco RED Series piston set is designed for just that. You get a full set of eight pistons, each forged from 2618 aluminum for the strength needed in demanding racing and power adder applications. The 4.000-inch bore size is a common starting point for many performance builds, and the 1.425-inch compression height works with a variety of popular combinations.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're smart. They feature horizontal slot oiling in the pin bores to keep the wrist pins and connecting rod small ends well-lubricated, which is crucial for longevity under high loads. The dedicated forgings allow for an optimized, strutted design that maximizes strength while keeping weight down. Plus, each set comes complete with premium rings, so you don't have to source those separately. An accumulator groove is also included to help maintain consistent ring seal and power delivery.

These pistons also feature an ArmorGlide skirt coating. This isn't just for looks; it helps reduce friction and noise during operation, and it also works to reduce wear on both the piston skirt and the cylinder wall. It's a well-built set designed to give you a competitive edge whether you're on the drag strip or the circle track. Keep in mind these are not CARB approved and cannot be shipped to California.
