SACHS RCS 140 S2.6 Racing Clutch Disc 881864002423
Ultra-lightweight sintered metal clutch disc with 2.6 mm lining thickness for SACHS RCS 140 racing clutches
The SACHS RCS 140 S2.6 sintered metal clutch disc 881864002423 from ZF Motorsport is a high-quality driven plate for modular SACHS RCS 140 multi-plate racing clutches. It combines the very compact 140 mm diameter with just 2.6 mm lining thickness and is designed for the lowest possible rotating mass, immediate power transmission and fast rpm changes in motorsport.
This version is aimed at applications where maximum agility, short shift times and precise engagement are the main priorities. Compared with S3.4, S5.2 and S7.8, the S2.6 offers the lowest lining thickness and therefore the lowest moment of inertia within the RCS 140 sintered metal clutch discs.
The RCS 140 format is especially suitable for motorsport vehicles with limited installation space and a consistently lightweight clutch layout. The 2.6 mm sintered metal clutch disc is therefore a technical solution for formula cars, sprint applications, compact touring cars and rally vehicles where spontaneous response is more important than increased wear reserve.
The part number 881864002423 identifies the specifically selected version with the matching hub profile for the respective gearbox input shaft. The clutch disc is intended for use within approved SACHS RCS 140 clutch configurations.

Technology
Sintered metal 2.6 mm
The SACHS RCS 140 S2.6 sintered metal clutch disc 881864002423 is designed for low moment of inertia, fast rpm changes and immediate power transmission. The sintered friction lining supports very direct engagement behaviour and clear feedback in motorsport use.
The 2.6 mm lining thickness reduces the rotating mass in the clutch pack to a minimum. Compared with S3.4, S5.2 and S7.8, this variant does not focus on maximum wear reserve, but on particularly fast response during short and intensive load phases.
Thanks to the 140 mm diameter, the clutch disc remains extremely compact. The S2.6 version is therefore suitable for motorsport vehicles where limited installation space, low weight and precise power transmission are consistently prioritized.
Hub profile
The hub profile of the SACHS RCS 140 S2.6 clutch disc 881864002423 is matched to the respective gearbox input shaft. This creates an accurate connection between clutch disc and gearbox, which is essential for clean power transmission and high operating reliability in motorsport.
When replacing a worn clutch disc, the existing hub length version of the SACHS RCS 140 clutch must be retained exactly. For new builds, conversions or individual assembly of an RCS 140 clutch pack, only the hub length combinations factory-approved by ZF Race Engineering for the respective clutch configuration may be used.
Before installation, the hub profile should be checked against the existing gearbox input shaft as well as the clutch cover, intermediate plates, pressure plate and approved RCS 140 configuration.
SACHS RCS 140 system
As part of the modular SACHS RCS 140 clutch system, the clutch disc is combined with approved pressure plates, intermediate plates and clutch covers. The decisive factors are the number of discs, lining thickness, installation height and the correct setup of the entire clutch pack.
The part number 881864002423 identifies the specific version of this SACHS RCS 140 S2.6 sintered metal clutch disc. For safe function, clutch disc, friction partners, clutch cover, pressure plate, intermediate plates and installation dimensions must be considered as a complete system.
