SACHS PERFORMANCE 881864002327 Clutch Disc RCS 140-S5.2

Description SACHS PERFORMANCE 881864002327 Clutch Disc RCS 140-S5.2

The SACHS RCS 140 5.2 sintered clutch disc is engineered for extreme heat resistance and wear life. Its compact dimensions deliver high Torque capacity with low mass, making it ideal for rally, circuit racing, and disciplines with repeated race starts.

Unlike 2.6 mm and 3.4 mm RCS clutch discs, the Friction material is provided by separate sintered pads riveted to the carrier in a paddle-style design rather than a thin overlay. This adds wear reserve, increases thermal capacity, and keeps friction levels consistent under back-to-back launches.

Compared with a 7.8 mm pad clutch disc, the 5.2 mm version maintains a lower moment of inertia for faster response. It also enables triple-plate packages, such as the RCS 3/140 5.2, for extreme transmissible Torque in a compact stack. The high-temperature sintered Friction material maintains bite and stable μ for confident launches and precise modulation. In rigid-hub form, the clutch engages directly for aggressive starts and razor-sharp shifts.

Technology

The SACHS RCS 140 5.2 sintered clutch disc from ZF Motorsport is a racing-grade choice for maximum durability. Compared with organic linings, it withstands higher temperatures and rpm and is far less sensitive to dirt or oil.

The sintered pads deliver a strong initial bite with quick, positive engagement off the line. The clutch disc also transfers significantly higher Torque, suiting high-output race cars.

As a core element of the modular SACHS RCS 140 clutch system, it is calibrated for motorsport applications ranging from rally and autocross to circuit racing.

SACHS RCS Hub

RCS 140 5.2 clutch discs are available with multiple spline profiles precisely matched to the gearbox input shaft for maximum fit quality and Torque transfer in racing use.

Hubs are offered in various Lengths, including extra short, short, medium, and long, to suit packaging and release geometry. The modular RCS 140 concept enables a tailored, low-inertia motorsport clutch with maximum performance and durability.
