Wiseco Chevy SB RED Series Piston Set 4030in Bore 1250in Compression Height 0927in Pin - Set of 8

Forged from 2618 aluminum, these Wiseco RED Series pistons are built for the demands of performance racing and power adder applications. The RED (Race Engineered Design) series uses dedicated forgings for each engine platform, allowing for an optimized strutted design that maximizes strength while keeping weight down. This attention to detail is crucial when you're pushing an engine hard, whether on the drag strip or the circle track.

You'll find horizontal slot oiling in the pin bores, which is a smart feature that ensures consistent lubrication for the wrist pin and the small end of the connecting rod. This helps maintain proper function and longevity 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 there to reduce friction and noise, while also minimizing wear on the piston skirt and cylinder wall.

This set includes premium rings, so you won't have to source them separately, making your rebuild process smoother. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for Chevrolet Small Block engines with a 4.030 inch bore.
