Wiseco RED Series Chevy Small Block 400 4.125in Bore 1.125in CH -12.00 CC Piston Set

If you're building a performance Chevrolet Small Block 400 engine, this Wiseco RED Series piston set is built to handle the demands of racing and power adder applications. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see hard use like drag racing or circle track. Wiseco's Race Engineered Design (RED) process ensures each piston is optimized for its specific application, balancing strength with a manageable weight.

You'll find features like horizontal slot oiling in the pin bores, which helps keep the wrist pin and connecting rod small end properly lubricated for a longer service life. The accumulator groove is included to help maintain consistent ring seal, ensuring you get the most power out of every combustion cycle. Plus, each set comes complete with premium rings, so you don't have to source them separately. The ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall.

This set is designed for a 4.125 inch bore with a 1.125 inch compression height and includes a 0.927 inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that needs reliable, strong components, this Wiseco RED Series piston set is a solid option.
