The Mahle MS Piston Set designed specifically for Chevrolet LS7 engines delivers high-performance components suitable for demanding applications. These pistons feature a 4.125-inch bore diameter and a 4-inch stroke, engineered to optimize power output and engine efficiency. Constructed with precision, the set includes pistons with a 0.927-inch pin diameter and a 25.0cc dish volume, contributing to a compression ratio of approximately 9.4:1. The set comprises eight pistons, ensuring compatibility with your LS7 engine build and delivering reliable performance across a variety of automotive applications.
Each piston is coated with phosphate, Grafal, and a hard anodized top ring groove, providing enhanced durability and wear resistance under high-stress conditions. The phosphate coating reduces friction and prevents corrosion, while the Grafal layer offers additional protection, extending the lifespan of the pistons. The hard anodized finish in the top ring groove ensures optimal ring seating and sealing, contributing to improved compression and power output. These features collectively enhance engine longevity and performance, making the Mahle pistons a dependable choice for enthusiasts and professionals alike.
Designed for high-performance automotive applications, these pistons are not carb-approved and require acknowledgment of carburetor restrictions. They are suitable for engines where air freight is permitted, but not recommended for environments requiring EPA compliance. Crafted from 2618 aluminum alloy, these pistons combine strength with lightweight properties, supporting high RPM operation and reducing overall engine weight. Whether you're rebuilding an LS7 or customizing a high-performance engine, the Mahle MS Piston Set offers precision engineering and durable construction to meet rigorous demands.
