Wiseco Chevy Small Block 4.130in Bore 1.060in CH 12.00 CC Piston Set

If you're building a high-performance Chevy Small Block engine for serious racing or heavy-duty applications, you need pistons that can handle the stress. This set of eight forged pistons from Wiseco is designed specifically for that purpose. They feature a 4.130-inch bore and a 1.060-inch compression height, making them a solid choice for many popular Small Block Chevy builds.

Wiseco crafts these Professional Series pistons from 2618 aluminum, which offers improved tensile strength over standard aluminum alloys. This means they can better withstand the extreme pressures and temperatures found in severe duty race engines. The pistons also come with precision ring grooves, anti-detonation grooves, and other features to enhance ring seal, ensuring efficient combustion and preventing blow-by. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown ensures accuracy and consistency across the set.

For builders who demand reliability under extreme conditions, these pistons include forced pin oiling to keep the wrist pins properly lubricated. While these pistons are built for performance, please note they are not CARB approved and cannot be shipped to California. This set is designed for builders who are serious about extracting maximum performance and durability from their Small Block Chevy engine.
