Wiseco Chevrolet Direct Injected LT1 6.2L Piston kit 3.622 Stroke, 4.065 Bore, 11.7:1 CR

If you're rebuilding the engine in your Chevrolet LT1 6.2L for serious performance, a strong set of pistons is where you start. This Wiseco Professional Series piston kit is built for demanding race applications where durability and consistent performance are critical. These aren't your average pistons; they're designed from the ground up to handle the stress of heavy to severe duty builds.

Wiseco forges these pistons from 2618 aluminum right here in the USA, giving them improved tensile strength for high-stress environments. You'll find precision ring grooves, anti-detonation features, and enhanced ring seal designs to keep everything working together smoothly under pressure. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and keep operation quieter. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pins lubricated.

This kit is specifically sized for a 4.065 inch bore and features a 11.7:1 compression ratio, making it suitable for many performance engine builds. Remember, these pistons are not CARB approved and cannot be shipped to California. For a robust engine rebuild targeting high performance, this Wiseco kit offers a well-built foundation.
