Wiseco RED Series Chevrolet Big Block 4.560in Bore 1.215in CH 18.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of high-performance Chevrolet Big Block engines. The RED (Race Engineered Design) series uses dedicated forgings to create an optimized strutted design, maximizing strength while keeping weight down. This is crucial for engines that see heavy use in drag racing or circle track applications.

You'll find horizontal slot oiling in the pin bores, which is a smart detail that ensures the wrist pin and small end of the connecting rod stay well-lubricated, contributing to a longer service life under stress. Each set also comes with an accumulator groove designed to help maintain a consistent ring seal, keeping power delivery steady. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the piston skirt and cylinder wall.

This set includes premium rings, so you won't need to source those separately. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a serious performance engine, these pistons offer a well-built foundation.
