MADE TO MAKE A DIFFERENCE
SACHS OE-quality clutches stand for durability, comfort and reliability. Until now we offered a retrofitted reinforced version with a performance lining. In the latest OE revision this performance clutch lining is factory-installed – and that exact current revision is what we deliver to you as a performance clutch. You get the familiar performance advantage, combined with the assurance of the most recent manufacturer specification.
6 STRONG REASONS
Higher transferable torque vs. previous series status
Factory-fitted: latest OE performance lining with increased thermal reserve
Optimized burst speed and durability through current revision
Longer service life
Easy replacement of the stock clutch
Complete kit incl. release bearing – ready to install

Technical details
HIGH LOAD CAPACITY
The latest OE revision uses an organic performance clutch lining with higher friction coefficient, very good fade resistance and reduced wear. We supply this revision only – tested by us and released for your model – so you get the performance characteristics without additional modification.
HIGH TRANSMISSIBLE TORQUE
Compared with older series levels, the current performance lining enables higher transferable torque with a stable bite point – ideal for mild power upgrades (e.g. software tuning), trailer operation and high mileages.
DAILY DRIVABILITY
Launch behaviour remains close to stock and easy to modulate. You benefit from the performance of a reinforced system – with the comfort of a latest-generation OE clutch.
Clutch pressure plate XTend
The pressure plate with automatic wear compensation decouples the lining wear from the diaphragm spring movement. The compensation mechanism constantly registers the reduction of the lining and reliably compensates for the gap by turning an adjusting ring. As a result, the force ratios remain constant and the service life is extended, as the pads can be worn further.
Quality Made in Germany
The performance lining consists of a glass-fibre-reinforced, layered friction lining construction with copper reinforcement. The elastomer/resin binder is tuned with friction modifiers and fillers – for a consistent friction coefficient, reduced fade and more comfort across the entire wear window.
