Wiseco Chevy Big Block 4.350in Bore 1.270in CH 25.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who need top-tier performance and durability in their Chevy Big Block engines. These aren't just any pistons; they're designed and forged in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial when you're pushing an engine hard.

You'll find a lot of attention to detail here. The precision ring grooves, anti-detonation grooves, and other features are there to improve ring seal, meaning better compression and more power. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and keep things quieter. The fully machined crown and forced pin oiling are further evidence that these pistons are built to handle the demands of heavy to severe duty race builds. If you're serious about getting the most out of your Big Block, these pistons are made to help you remove your limits.

This set includes eight pistons, designed for a 4.350-inch bore with a 1.270-inch compression height. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For optimal installation and performance, always refer to the manufacturer's detailed instructions and specifications.
