Wiseco Chevy SB RED Series Piston Set 4135in Bore 1215in Compression Height 0927in Pin - Set of 8

If you're building a high-performance Chevrolet Small Block engine, especially for demanding applications like drag racing or circle track, you need pistons that can handle the stress. This Wiseco RED Series piston set is built for just that. They're forged from 2618 aluminum, a material known for its tensile strength, which is crucial when you're pushing an engine hard or adding power adders.

Wiseco's Race Engineered Design (RED) process means these pistons aren't just strong; they're also precisely machined to give you an edge. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pin and small-end of the connecting rod well-lubricated, helping to ensure a long service life even under high loads. The dedicated forgings allow for an optimized, engine-specific strutted design, balancing strength with a manageable weight. Plus, the ArmorGlide skirt coating is there to reduce friction and noise, while also cutting down on wear to the piston skirt and cylinder wall. An accumulator groove is also included to help maintain consistent ring seal and power output.

This set includes premium rings, so you won't need to source those separately. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
