Wiseco RED Series Chevy Big Block 4.320in Bore 1.270in CH 26.00 CC Piston Set

When you're building a serious performance Chevy Big Block, you need parts that can handle the stress. This set of eight Wiseco RED Series pistons is forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for racing and boosted applications. These pistons are engineered with Race Engineered Design (RED) principles to give you a competitive edge.

Wiseco has included several thoughtful features to ensure longevity and performance. The horizontal slot oiling in the pin bores keeps the wrist pins and connecting rod small ends properly lubricated, which is vital for extended service life under demanding conditions. Each piston also features an accumulator groove, designed to help maintain consistent ring seal and power output. The dedicated forgings allow for an optimized, engine-specific strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating works to reduce friction and noise, while also minimizing wear on the piston skirts and cylinder walls.

This set comes complete with premium rings, so you won't need to source them separately. These pistons are manufactured in the USA, reflecting a commitment to quality and performance for drag racing, circle track, and other high-performance V8 platforms.
