Wiseco RED Series Chevrolet Big Block 4.350in Bore 1.645in CH 35.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing, the Wiseco RED Series pistons are designed to handle the demands of the track. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see heavy use, especially with power adders like turbochargers or superchargers.

Wiseco's Race Engineered Design (RED) process means these pistons aren't just strong; they're also precisely machined for a competitive edge. You'll find horizontal slot oiling in the pin bores to keep the wrist pins and connecting rod small ends well-lubricated, which is key for long service life under stress. The dedicated forgings allow for an engine-specific strutted design, balancing strength with a low weight. Plus, the ArmorGlide skirt coating helps 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 those separately, and an accumulator groove helps maintain consistent ring seal and power output.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust build that's ready for competition, this set offers a well-built solution.
