Wiseco RED Series Ford Small Block 4.000in Bore 1.230in CH -5.00 CC Piston Set

If you're building a performance Ford Small Block engine, Wiseco's RED Series pistons are a solid option. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for handling the demands of racing and boosted applications. They are engineered and machined right here in the USA, ensuring a high level of precision in their construction.

Wiseco has incorporated several thoughtful features into these pistons to enhance performance and longevity. The horizontal slot oiling in the pin bores helps keep the wrist pin and connecting rod small end well-lubricated, which is vital for extended service life under stress. Dedicated forgings allow for an engine-specific strutted design, meaning Wiseco has optimized the strength-to-weight ratio for this particular application. Additionally, the ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall. An accumulator groove is also included to help maintain consistent ring seal and power output.

This set includes eight pistons, each designed for a 4.000-inch bore with a 1.230-inch compression height and a -5.00cc dish volume. Premium rings are included with each set, so you won't need to source those separately. Please note that these pistons are not CARB approved and cannot be shipped to California.
