Wiseco Chevy SB RED Series Piston Set 4135in Bore 1550in Compression Height 0927in Pin - Set of 8

When you're building a performance V8 engine, especially for demanding applications like drag racing or circle track, you need pistons that can handle the stress. This Wiseco RED Series piston set gives you exactly that. You get a complete set of eight forged pistons, ready to be installed in your Chevrolet Small Block engine. Each piston is forged and machined right here in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for performance racing and when you're adding power adders.

Wiseco's Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're smart. They feature dedicated forgings that allow for an optimized, engine-specific strutted design, balancing strength with a low weight. You'll also find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pin and small-end of the connecting rod properly lubricated, helping to ensure a long service life. Plus, each set comes complete with premium rings, so you don't have to hunt for compatible ones separately. An accumulator groove is also included to help maintain consistent ring seal and power output.

To further reduce friction and wear, these pistons are treated with an ArmorGlide skirt coating. This not only helps quiet things down but also reduces wear on both the piston skirt and the cylinder wall. This set is designed for a 4.135-inch bore, a 1.550-inch compression height, and uses a 0.927-inch pin. Please note that these pistons are not CARB approved and cannot be shipped to California.
