Wiseco Chevy LSX Junkyard Dog 6.0L +9cc Dome 4.00 Bore .945in Pin NA/Boost/Nitrous Drop-In Pistons

If you're building a high-performance Chevy LSX engine, especially one that needs to handle serious power from boost or nitrous, a solid set of pistons is crucial. These Wiseco Professional Series pistons are designed for exactly that kind of demanding application. They're built to be a drop-in replacement for your stock 6.0L pistons, but with a significant upgrade in strength and durability.

Wiseco forges these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength over cast or hypereutectic designs. They feature precision ring grooves, an anti-detonation groove, and other features to ensure a good seal and prevent detonation, which is key when you're pushing the limits. The crown is fully machined for accuracy, and they even come with forced pin oiling to keep things well-lubricated under stress. Plus, the ArmorGlide skirt coating helps reduce friction and noise, and makes them more resistant to seizing.

This set is designed for a 4.000 inch bore with a +9cc dome, which is a common configuration for naturally aspirated, boosted, or nitrous-fed LSX builds. They use a standard .945 inch pin diameter, making them compatible with many popular connecting rods. Remember, these are not CARB approved and cannot be shipped to California.
