SACHS RCS 200 Clutch Housing
Forged clutch cover for modular SACHS RCS 200 racing clutches
Lightweight, stiff and durable: the SACHS RCS 200 clutch housing is the central support structure of ZF Motorsport’s modular Racing Clutch System and has been developed for high thermal and mechanical loads in racing.
The forged RCS 200 version reduces weight and moment of inertia compared with a machined housing while offering high strength, precise component guidance and robust performance in use.
Versions
System: SACHS RCS 200 multi-plate racing clutch
Configuration: for 1-, 2- and 3-plate versions
Release diameter: 49 mm
Friction materials: carbon, sintered metallic and organic friction linings
Note: the clutch cover housing must be combined with approved RCS 200 pressure plates, intermediate plates and clutch discs specific to the series. Select according to the number of plates, friction material and application profile.
Benefits
Forged aluminium for high strength with reduced weight
Up to 8 % weight reduction compared with a machined housing
Up to 14 % lower moment of inertia for spontaneous response
High housing stiffness for precise modulation and accurate component guidance
Supports precisely defined clamp load for repeatable torque transmission
Wear-resistant, patented aluminium coating to protect against friction, fit and corrosion wear
Efficient heat dissipation through motorsport-specific housing geometry
Technology
RCS 200 clutch housing
Function: The clutch cover (housing) accommodates the pressure plate, intermediate plates and clutch discs, guides the components precisely and transmits torque within the modular RCS system. The high housing stiffness supports defined modulation, stable component positioning and reproducible shifts.
Design: High-strength forged aluminium with series-specific RCS 200 geometry. The forging process increases load capacity and enables a lightweight, torsionally stiff design with reduced moment of inertia.
Clamp load: In combination with the pressure plate, diaphragm spring, intermediate plates and clutch discs, the clutch housing contributes to precisely defined clamp load. This supports repeatable torque transmission and consistent engagement behaviour in motorsport operation.
Coating: The full-surface, extremely wear-resistant aluminium coating reduces friction and fit wear, protects against corrosion and improves the service life of the clutch cover (housing) in racing use.
Thermal management: The special housing geometry supports efficient heat dissipation and stabilises the temperature window of the clutch pack – particularly important with short shift windows, high engine speeds and repeated thermal load.
Installation notes
Installation & flywheel
Flywheel contour: The flywheel contour must be checked when using the SACHS RCS racing clutch. Precise machining of the flywheel is required for clutch function, runout and long-term performance.
Fastening: M8 screws of at least property class 10.9 with internal hexagon and washers are recommended for fastening the clutch. The tightening torque is 25 Nm.
Service inspection: Check housing guides, contact surfaces, coating and fits regularly. In the event of wear, damage or impermissible play, assess adjacent components together to ensure clamp load, torque transmission and shift precision over the long term.
