Description

The Mahle MS piston set is engineered specifically for GM LS engine applications, delivering high performance and durability for your rebuild or upgrade. Designed for engines with a 428 cubic inch displacement, these pistons feature a 4.075-inch bore diameter and a 4.125-inch stroke to optimize power output and efficiency. The 6.125-inch connecting rods and 0.927-inch wrist pins ensure a robust connection between the piston and crankshaft, supporting high RPM operation and long-term reliability.
Constructed from high-quality 4032 aluminum alloy, these pistons are lightweight yet strong, with a compression ratio of 10.8:1 that balances performance and fuel efficiency. The pistons are coated with phosphate and Grafal to enhance wear resistance, reduce friction, and improve overall durability under demanding conditions.
Designed for automotive use, these pistons are not carb-legal and require acknowledgment of carb regulations during installation. They are suitable for high-performance rebuilds, racing applications, and hot rod projects where maximizing displacement and power is essential. The set includes eight pistons, making it ideal for complete engine rebuilds or modifications aimed at increasing horsepower and torque.
Note that these pistons are not EPA compliant and are not available for air freight, emphasizing their specialized purpose for performance-oriented automotive builds. Proper installation and compatibility checks are recommended to ensure optimal engine performance and longevity.

  • Designed for GM LS engines with 428 cubic inch displacement
  • Bore diameter of 4.075 inches for optimal fit and performance
  • Stroke of 4.125 inches to increase engine displacement
