Wiseco Chevy SB RED Series Piston Set 4130in 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 Chevy Small Block engines. The Race Engineered Design (RED) philosophy means they're not just strong, but also precisely machined to give you a competitive edge, whether you're hitting the drag strip or the circle track.

Wiseco machines these pistons in the USA, using dedicated forgings that are optimized for strength and weight. You'll find horizontal slot oiling in the pin bores, which is a smart way to keep the wrist pin and small-end of the connecting rod well-lubricated, crucial for keeping things running smoothly over the long haul. They also come with an accumulator groove to help maintain consistent ring seal and power, and an ArmorGlide skirt coating that works to reduce friction and noise while also cutting down on skirt and cylinder wear.

This set includes premium rings, so you won't have to source them separately. Keep in mind these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance engine and need reliable, well-built internals, this set is a solid option.
