Wiseco RED Series Chevy LS 4.005in Bore 1.105in CH -10.00 CC Piston Set

If you're building a high-performance Chevy LS engine, this Wiseco RED Series piston set is built to handle the demands of racing. These pistons are forged from 2618 aluminum, a material chosen for its tensile strength, which is crucial for engines that see heavy use in applications like drag racing and circle track. The RED series stands for Race Engineered Design, meaning Wiseco has focused on features that give you a competitive edge and the durability you need.

Wiseco has incorporated several thoughtful details into these pistons. The horizontal slot oiling in the pin bores helps keep the wrist pin and the small end of the connecting rod properly lubricated, which is key for a long service life under stress. Dedicated forgings allow for an optimized, engine-specific strutted design, balancing strength with a manageable weight. You'll also find an ArmorGlide skirt coating, which works to reduce friction and noise while also minimizing wear on the piston skirt and cylinder wall. Each set comes complete with premium rings, so you won't need to source those separately. An accumulator groove is included to help maintain consistent ring seal and power output.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. This set is designed for 8-cylinder engines and includes everything needed to outfit your LS build.
