Wiseco Chevy Small Block 4.040in Bore 1.000in CH -25.00 CC Piston Set

If you're rebuilding a high-performance Chevrolet small block engine for serious racing or heavy-duty use, a strong set of pistons is crucial. This Wiseco Professional Series piston set is built from 2618 aluminum, a material chosen for its improved tensile strength, making these pistons well-suited for the demands of severe duty applications. The 4.040-inch bore size and -25.00cc dish volume are specific dimensions to consider for your engine build.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features designed to improve ring seal. They also include an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown and forced pin oiling further demonstrate the focus on durability and performance for racing environments. This set includes eight pistons, ready for your next build.

When planning your engine build, remember that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or refer to Wiseco's technical documentation for specific installation requirements and compatibility with other engine components.
