Wiseco RED Series Chevrolet Big Block 4.560in Bore 1.270in CH 21.00 CC Piston Set

Wiseco is well-known for its high-performance forged pistons, and their RED Series takes that reputation a step further. These pistons are built using Race Engineered Design, meaning they're crafted with the strength and durability that performance engines demand, along with precision machining for a competitive edge. They're a cornerstone for anyone building a serious V8 for drag racing or circle track applications.

Crafted from 2618 aluminum right here in the USA, these pistons are forged for tensile strength that holds up under the stress of performance racing and power adder setups. The RED0097X6 set features horizontal slot oiling in the pin bores to keep the wrist pins and small-end lubrication optimal, which is crucial for a long service life. Dedicated forgings allow for an engine-specific strutted design that maximizes strength while keeping weight down. You'll also find an accumulator groove that helps maintain consistent ring seal and power delivery. Plus, the ArmorGlide skirt coating works to reduce friction and noise, while also cutting down on skirt and cylinder wear.

This set includes premium rings, so you won't need to source those separately. Keep in mind these pistons are not CARB approved and cannot be shipped to California.
