Wiseco RED Series Ford Small Block 4.040in Bore 1.230in CH -5.00 CC Piston Set

If you're building a performance Ford Small Block engine, Wiseco's RED Series piston set is a solid choice. These pistons are forged from 2618 aluminum, a material known for its tensile strength, making them well-suited for the demands of racing and applications with power adders like turbochargers or superchargers. The Race Engineered Design (RED) philosophy behind these pistons means they're not just strong, but also precisely machined to give you an edge.

Wiseco has incorporated several features to ensure durability and performance. Horizontal slot oiling in the pin bores helps keep the wrist pins and connecting rod small ends properly lubricated, which is crucial for long service life under stress. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. You'll also find an accumulator groove, which helps maintain consistent ring seal and power delivery. Plus, each set comes complete with premium rings, so you won't need to source those separately.

The pistons also feature an ArmorGlide skirt coating. This coating is designed to reduce friction and noise during operation, while also minimizing wear on the piston skirts and cylinder walls. These pistons are designed for a 4.040 inch bore with a 1.230 inch compression height and a -5.00cc dish, and they use a 0.927 inch pin diameter. Please note that this piston set is not CARB approved and cannot be shipped to California.
