Wiseco Chevy Big Block 4.125in Bore 1.760in CH 15.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing or heavy-duty applications, a solid set of pistons is crucial. This Wiseco Professional Series piston set is designed to handle the extreme demands of severe duty builds, offering a significant step up from stock components. They are engineered and forged in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress.

Wiseco has packed these pistons with features aimed at maximizing performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is vital for compression and preventing detonation. The pistons also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, contributing to overall engine health and longevity under load. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins properly lubricated.

This set includes eight pistons, ready to be installed in your Chevrolet Big Block with a 4.125-inch bore. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a race-ready engine build, these Wiseco pistons are a well-built choice designed to withstand the rigors of competition.
