Description

Mercedes M275 Dual Valve Springs & Lightweight Retainers Kit

High-performance dual valve spring kit for Mercedes-Benz M275 V12 engines. Designed for high-boost, high-horsepower, and high-RPM applications, this package provides exceptional valve control and completely eliminates the risk of valve float in demanding conditions.

The kit combines dual valve springs with lightweight hardened tool steel retainers and dedicated spring locators. This setup delivers superior valve train stability while maintaining excellent durability for both street and motorsport use.

The lightweight retainers offer greater strength and wear resistance than the factory components while reducing valvetrain mass. This helps improve valve control at elevated engine speeds and supports safe RPM increases when combined with the appropriate supporting modifications.
