The 7-speed dual-clutch transmission (DCT) used in the Mercedes-AMG C190 platform is engineered for high-performance applications, delivering fast and precise gear changes across models such as the AMG GT, GTS, GTC, and GTR.

When increasing engine output, especially in tuned or modified AMG builds, upgrading the clutch system becomes essential to ensure the transmission can reliably handle the additional torque and maintain consistent performance under load.

DEKA specializes in high-performance clutch upgrades, utilizing precision engineering and the replacement of high-wear OEM components with CNC-machined billet parts, upgraded friction materials, and reinforced internal components. Each kit is assembled with attention to durability, performance, and long-term reliability.

Benefits include increased torque capacity, improved power transfer, reduced clutch slippage, and enhanced durability under aggressive driving conditions.

Each stage of upgrade is designed to match different performance levels, driving styles, and build requirements.
