Wiseco RED Series Ford Small Block 4.030in Bore 1.280in CH -5.00 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 available for many popular domestic V8 engines, making them a cornerstone for everything from drag racing to circle track builds.

Each piston features horizontal slot oiling in the pin bores to keep the wrist pin and small end of the connecting rod well-lubricated, which is crucial for a long service life. The dedicated forgings allow for an engine-specific strutted design that maximizes strength while keeping weight down. You'll also find an accumulator groove that helps maintain consistent ring seal and power output. Plus, the ArmorGlide skirt coating works to reduce friction and noise, while also cutting down on skirt and cylinder wear. This set comes complete with premium rings, so you won't need to source those separately.

This piston set is designed for a 4.030 inch bore with a 1.280 inch compression height and a -5.00cc dish volume. The pin diameter is 0.927 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning.
