Wiseco RED Series Chevy LS 4.185in Bore 1.105in CH -10.00 CC Piston Set

If you're building a high-performance Chevy LS engine for serious racing, the Wiseco RED Series pistons are built to handle the demands. These aren't your average replacement pistons; they're forged from 2618 aluminum, a material chosen for its tensile strength, which is crucial when you're pushing an engine hard, whether that's on the drag strip or the circle track. The Race Engineered Design (RED) process means these pistons are specifically optimized for strength and weight, giving you a competitive edge.

Wiseco machines these pistons in the USA, and they've included some smart features to ensure longevity and performance. You'll find horizontal slot oiling in the pin bores, which keeps the wrist pin and connecting rod small end well-lubricated, a critical factor for preventing wear under high stress. They also come with an ArmorGlide skirt coating that not only cuts down on friction and noise but also reduces wear on the piston skirt and cylinder walls. Plus, each set includes premium rings, so you won't have to hunt for compatible ones, and an accumulator groove helps maintain a consistent ring seal for maximum power.

This set is designed for a 4.185-inch bore and features a 1.105-inch compression height, with a -10.00 CC dish volume. Remember, these pistons are not CARB approved and cannot be shipped to California. They are a solid option for anyone rebuilding a domestic V8 for performance applications.
