Wiseco RED Series Ford Small Block 4.040in Bore 1.280in CH -5.00 CC Piston Set

If you're building a high-performance Ford Small Block engine for racing, the Wiseco RED Series pistons are a solid choice. These aren't your average pistons; they're built using Race Engineered Design (RED) principles to give you the strength and durability needed for demanding applications like drag racing and circle track, while also incorporating precision features that help you gain a competitive edge.

Crafted in the USA from 2618 aluminum, these pistons are forged and then machined to maximize their strength-to-weight ratio, meaning they can handle serious abuse without adding unnecessary mass to your rotating assembly. They feature horizontal slot oiling in the pin bores to ensure the wrist pin and small end of the connecting rod stay well-lubricated, which is crucial for long service life under high stress. The ArmorGlide skirt coating is a nice touch, as it helps reduce friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. Plus, each set comes complete with premium rings, so you won't have to hunt for those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

This set is specifically designed for a 4.040-inch bore with a 1.280-inch compression height and a -5.00cc dish, making them suitable for a variety of performance builds. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
