Wiseco RED Series Chevrolet Big Block 4.280in Bore 1.270in CH 28.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for racing, like drag or circle track, you need pistons that can handle the stress. This Wiseco RED Series piston set is built for those demanding applications. They're forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing serious power, especially with forced induction or other power adders.

Wiseco's Race Engineered Design (RED) process means these pistons are more than just strong; they're precisely machined for a competitive edge. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pin and connecting rod small end well-lubricated, helping to ensure a long service life even under heavy use. The dedicated forgings allow for an engine-specific strutted design, maximizing strength while keeping weight down. Plus, the ArmorGlide skirt coating isn't just for show – it actively reduces friction and noise, and it cuts down on skirt and cylinder wall wear. Each set comes complete with premium rings, so you won't have to hunt for compatible parts, and an accumulator groove helps maintain consistent ring seal for reliable power delivery.

This set is designed for a 4.280-inch bore and features a 1.270-inch compression height. Remember, these pistons are not CARB approved and cannot be shipped to California. They are made in the USA.
