Do not sacrifice the grip and traction of your Clio 2 X65 Cup. Without this SADEV Belleville Washer Galbe 1 (Ref.

The Belleville Washer Galbe 1 (Reference F9001096) is a fundamental element in the adjustment of your SADEV limited slip differential integrated into the ST75-14 sequential gearbox of your Renault Clio 2 X65 Cup. Its role is to maintain the mechanical preload on the internal friction discs. If this washer is fatigued, flattened, or replaced with the wrong reference, the limited slip differential becomes ineffective: you lose the necessary torque transfer force. Direct consequences: excessive wheel spin of the inside wheel on corner exit (time loss) and accelerated wear of the internal discs and plates. Protecting your performance in competition requires choosing genuine SADEV parts.
This concave washer is specially designed to provide the necessary return force for differential calibration.

Limited slip differential adjustment is technical, hence these frequent questions:
To maintain the maximum efficiency and performance on the corners of your Clio Cup, regular checking and replacement of the concave washers are crucial. Use this genuine SADEV Belleville Washer F9001096 during differential overhaul or ST75-14 differential repair. We ensure you have access to all necessary plain and friction discs with quick shipping.
