Wiseco RED Series Chevrolet Big Block 4.310in Bore 1.270in CH 28.00 CC Piston Set

These Wiseco RED Series pistons start with a 4.310-inch bore and are forged from 2618 aluminum, a material chosen for the high tensile strength needed in demanding performance racing and power adder applications. The RED series, which stands for Race Engineered Design, is built to give your engine the durability and precision machining required to gain a competitive edge, whether you're on the drag strip or the circle track. They are specifically designed for popular domestic V8 platforms, forming the backbone of many performance builds.

You'll find a few notable features that contribute to their longevity and performance. The horizontal slot oiling in the pin bores is a smart touch, ensuring optimal lubrication for the wrist pin and the small end of the connecting rod, which is critical for a long service life under stress. Wiseco also uses dedicated forgings for each engine application, allowing for an optimized, strutted design that maximizes strength while keeping weight down. To further reduce friction and wear, these pistons come with an ArmorGlide skirt coating, which also helps quiet down operation. Plus, each set includes premium rings, so you won't need to source those separately. An accumulator groove is also incorporated to help maintain consistent ring seal and power delivery.

Because these are performance pistons, it's important to note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
