Wiseco Chrysler Big Block Mopar 383/400/440 4.25 Bore 3.375 -10 Volume

When you're building a serious Mopar big block for heavy or severe duty, you need pistons that can handle the stress. This set from Wiseco gives you eight Professional Series forged pistons, ready to be installed in your Chrysler 383, 400, or 440 engine. They're designed to meet the demands of high-performance racing applications, offering a solid foundation for your engine build.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions. Wiseco has included precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The piston crowns are fully machined for accuracy, and they come with forced pin oiling to ensure proper lubrication. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when you're pushing your engine hard.

This set is specifically for a 4.25 inch bore with a -10cc volume, and features a 3.375 inch stroke. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
