Wiseco Chevy SB RED Series Piston Set 4185in Bore 1062in Compression Height 0927in Pin - Set of 8

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of high-performance racing and power adder applications. The RED (Race Engineered Design) series uses dedicated forgings to create an optimized, strutted design that maximizes strength while keeping weight down. This is crucial for engines that see hard use, whether on the drag strip or the circle track.

You'll find horizontal slot oiling in the pin bores, which is a smart detail that ensures consistent lubrication for the wrist pin and the small end of the connecting rod. This helps extend service life under high stress. Each set also comes with an accumulator groove designed to help maintain a consistent ring seal, which is key for keeping power where it belongs. Plus, the ArmorGlide skirt coating is applied to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder walls.

This set includes premium rings, so you won't need to source those separately. Wiseco pistons are engineered, forged, and machined in the USA, ensuring a well-built component for your performance engine build.
