Wiseco Chevrolet LS RED- LS 4.000in Stroke Flat Tops 4.030in Bore - Set of 8

These Wiseco RED Series pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for the demands of performance racing and engines with power adders. The Race Engineered Design (RED) process means they're not just strong, but also precisely machined to give you an edge on the track, whether you're into drag racing or circle track. They're built specifically for popular domestic V8 platforms like the Chevrolet LS engine.

You'll find horizontal slot oiling in the pin bores, which is a smart detail that keeps the wrist pin and small end of the connecting rod properly lubricated. This is crucial for ensuring a long service life, especially under high-stress conditions. The dedicated forgings allow for an engine-specific strutted design, balancing strength with weight to maximize performance. Plus, each set comes with premium rings, so you don't have to hunt for compatible ones, and an accumulator groove helps maintain consistent ring seal for steady power delivery.

The ArmorGlide skirt coating is another notable feature, working to reduce friction and noise while also minimizing wear on both the piston skirt and the cylinder wall. These pistons are manufactured and machined in the USA, ensuring a high standard of production for your performance build.
