Clutch Disc
SACHS RCS 140 2.6
Sintered metal 2.6 mm, rigid design
The SACHS RCS 140 2.6 sintered clutch disc is engineered for uncompromising motorsport use. With just 140 mm diameter and 2.6 mm friction thickness, it delivers an ultra-compact, lightweight package - ideal for formula cars, touring cars and rally cars where space and weight are critical.
Its high-load sintered friction material offers outstanding heat resistance and reliably transfers high torque under the harshest conditions. In rigid design, engagement is exceptionally direct, providing aggressive launches and lightning-fast bite off the line.
Key benefits at a glance:
High torque capacity
High thermal capacity
Low stack height
Higher burst speed
Extremely light - low mass and inertia
Highly resistant to dirt
Aggressive launch characteristics
The technology
Friction lining - sintered metal
The SACHS RCS 140 2.6 sintered clutch disc from ZF Motorsport is the go-to choice for peak racing performance. Compared with organic discs, it offers significantly higher thermal resilience, better high-rpm stability and superior resistance to dirt and oil.
The dedicated sintered friction material delivers a sharp response with hard launches and instant bite at race starts. It also transmits substantially higher torque, making it ideal for high-output race cars.
As a core element of the modular SACHS RCS 140 clutch system, it is perfectly matched to motorsport applications - from rally and formula to circuit racing.
SACHS RCS hub
SACHS RCS 140 2.6 discs are available with different spline hubs precisely matched to the gearbox input shaft. This ensures perfect fitment, reliable torque transfer and maximum durability in demanding race use.
Hubs are also offered in various lengths (extra short, short, medium, long). This allows optimal packaging within the bellhousing and correct actuation. The modular RCS 140 concept from ZF Motorsport enables a tailored race clutch with minimal inertia and maximum performance.
Quality Made in Germany
ZF Race Engineering has been among the technology leaders in motorsport for years. The combined know-how from top-level racing flows directly into the development of RCS racing clutches. State-of-the-art manufacturing methods, the highest quality standards and motorsport technologies make ZF Motorsport clutches the first choice for maximum performance and reliability - on circuits as well as in rallying, touring and endurance racing.
