STM Racing Dry Clutch Friction and Steel Plate Kit for Ducati Panigale V4/S Retrofit Clutch (2018-2026) ADU-0040

If you have already invested in the STM retrofit dry clutch for your Ducati Panigale V4/S, the ADU-0040 friction and steel plate kit is the sensible, cost-effective way to keep it performing exactly as intended — whether you are covering road miles between track days or pushing hard at every session.

Key Features

• Complete replacement kit engineered specifically for the STM retrofit dry clutch with 48-tooth basket fitted to the Ducati Panigale V4/S (2018-2026)
• Includes 8 friction plates (2.5 mm) delivering consistent, progressive clutch feel under repeated hard use
• 1 Steel Spring Plate (1.5 mm) maintains stable clamp load and resists fatigue over time
• 2 steel plates (1.5 mm) and 7 steel plates (2.0 mm) provide a carefully balanced stack for optimised durability and load capacity
• 100% made in Italy — STM's own production standards ensure dimensional accuracy and material consistency throughout
• Designed to withstand extreme track conditions while remaining perfectly usable for demanding road riders

Built for Reliability, Priced for Regular Use

Clutch plates on a high-performance dry clutch are a wear item — having the correct replacement kit to hand means downtime is minimal and the rebuild is straightforward. STM has engineered each component in the ADU-0040 to match the original specification of their retrofit system exactly, so there is no guesswork around shimming or stack height. The friction material and steel plate thicknesses have been selected to work together, giving progressive, predictable engagement whether you are filtering through traffic or launching off a pit-lane exit.

Italian Craftsmanship, Race-Proven Construction

STM's reputation in clutch technology comes from decades supplying Italian manufacturers and race teams. Every plate in this kit is produced in Italy to tight tolerances, ensuring even heat distribution across the clutch pack and extended service intervals compared with generic replacements. The combination of 2.5 mm friction discs and the mixed steel plate stack mirrors the configuration STM specifies from new, so performance after a rebuild matches the out-of-the-box experience.

Fitment and Compatibility

This kit is designed exclusively for use with the STM retrofit dry clutch conversion featuring a 48-tooth basket, fitted to the following models:

• Ducati Panigale V4 (2018-2026)
• Ducati Panigale V4 S (2018-2026)

This is a replacement plate kit for an existing STM retrofit dry clutch system and is not a standalone clutch conversion. Confirm your STM basket tooth count before ordering.
