Wiseco Chrysler HEMI 426 4.280in Bore 1.765 Compression Height +80cc Dome Top Pistons

When you're building a serious performance engine, especially a legendary Chrysler 426 Hemi, you need components that can handle the stress. This set includes eight forged pistons, precision-machined from 2618 aluminum, known for its improved tensile strength. They feature a +80cc dome top, a 4.280-inch bore size, and a 1.765-inch compression height, designed to work with specific engine configurations.

Wiseco engineers these pistons with features aimed at durability and performance in heavy to severe duty race applications. You'll find precision ring grooves, anti-detonation grooves, and other features to improve ring seal. The pistons also come with an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The fully machined crown and forced pin oiling further contribute to their robust design, making them a solid choice for demanding builds.

These pistons are forged and machined in the USA. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
