Wiseco RED Series Ford Small Block 4.000in Bore 1.280in CH -5.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for racing applications. This RED Series piston set is built for Ford Small Block engines that demand serious performance. These aren't your average pistons; they're forged from 2618 aluminum, a material chosen for its high tensile strength, which is exactly what you need when you're pushing an engine hard, especially with power adders like turbos or superchargers.

The Race Engineered Design (RED) means these pistons are specifically shaped for performance. They feature a strutted design that maximizes strength while keeping weight down, a crucial balance for racing. You'll find horizontal slot oiling in the wrist pin bores, which is a smart detail that keeps the wrist pin and the small end of the connecting rod properly lubricated, helping everything last longer under stress. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, and it also helps cut down on wear on both the piston skirt and the cylinder wall. Each set comes complete with premium rings, so you don't have to hunt for those separately.

This set is designed for a 4.000-inch bore with a 1.280-inch compression height and a -5.00cc dish, and it includes a 0.927-inch pin diameter. It's a set of 8 pistons. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
