Wiseco RED Series Chevrolet Big Block 4.530in Bore 1.270in CH 21.00 CC Piston Set

What you get in this kit are eight forged pistons designed for Chevrolet Big Block engines. These are Wiseco's RED Series pistons, built with Race Engineered Design principles to give you the strength and durability needed for serious performance applications, whether you're on the drag strip or the circle track. They're made from 2618 aluminum, a material chosen for its high tensile strength, which is crucial when you're pushing an engine hard or adding power adders.

Wiseco machines these pistons in the USA, and they've included some smart details. The horizontal slot oiling in the pin bores helps keep the wrist pins and connecting rod small ends well-lubricated, which is key for a long service life. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a low weight. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the piston skirts and cylinder walls. You also get premium rings included with each set, so you won't have to hunt for those separately. An accumulator groove is also part of the design, helping to maintain consistent ring seal and power output.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance Chevrolet Big Block, these pistons are a solid option designed to handle the demands of racing and power adders.
