Wiseco Chevy Big Block 4.605in Bore 1.060in CH 28.00 CC Piston Set

When you're building a serious performance Chevrolet Big Block engine, especially for racing or heavy-duty applications, the pistons are a critical component. This set from Wiseco is designed to handle the extreme demands of high-horsepower builds. They're crafted from 2618 aluminum, a material chosen for its excellent tensile strength, which is essential for maintaining integrity under intense combustion pressures and temperatures.

Wiseco has packed a lot of thought into these pistons. You'll find precision ring grooves that help ensure a solid seal, along with anti-detonation grooves to prevent pre-ignition. They also feature additional features aimed at improving ring seal, which is key for both power and efficiency. The crown of each piston is fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins well-lubricated. Plus, they include an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, all contributing to a more durable and efficient engine build.

This set is intended for 4.605-inch bore applications and includes eight pistons, along with premium rings. Remember that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for a robust, high-performance Big Block, these Wiseco pistons are built to take on the challenge.
