Stiff clutch spring for Küster servomotors
Stiff clutch spring for Küster servomotors.
With this coupling it is possible to prevent unpleasant noises from the exhaust flaps. Due to the higher rigidity compared to the standard spring, the flap is closed with a higher force, which can lead to the avoidance of noise.
Due to the large area of application, we cannot guarantee the function and durability of every vehicle. Use at your own risk.
The original clutch spring is replaced 1:1 by the stiff ASR variant.
Please check the pictures for comparison.
