Wiseco Chevy Big Block 4.625in Bore 1.270in CH 28.00 CC Piston Set

If you're building a serious performance engine for your Chevy Big Block, this Wiseco Professional Series piston set is a solid choice. These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over standard aluminum. That means they can handle the intense pressures and heat found in heavy to severe duty race builds without flexing or failing.

Wiseco has packed these pistons with features to ensure top performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for compression and power. They also come with a special ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and even makes operation quieter. The fully machined crown and forced pin oiling further contribute to their ability to withstand demanding applications.

This set includes eight pistons, each designed for a 4.625-inch bore with a 1.270-inch compression height and a 0.990-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for maximum performance and reliability in a high-stress engine build, these Wiseco pistons are built to go the distance.
