Wiseco Chevy Big Block 4.560in Bore 1.270in CH 15.00 CC Piston Set

If you're rebuilding the heart of a Chevy Big Block for serious racing or heavy-duty performance, you need pistons that can handle the stress. This set from Wiseco is built from the ground up for those demanding applications. They're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to resist deformation under extreme pressure.

Wiseco packs a lot of smart features into these pistons. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is critical for both power and engine longevity. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and even quiet things down a bit. The fully machined crown and forced pin oiling are details that show these are made for the long haul in tough conditions.

This set includes eight pistons, designed for a 4.560-inch bore with a 1.270-inch compression height. Keep in mind that these are not CARB approved and cannot be shipped to California. For a severe duty build, these are a solid option to consider.
