Differential Shimming Washer SADEV Clio R3 - 7711162220

The Invisible Danger of Incorrect SADEV Differential Shimming

In motorsport, overlooking a backlash or preload adjustment to the nearest tenth of a millimeter is a guaranteed recipe for expensive mechanical failure. Without this genuine manufacturer differential adjustment shim, you expose your SADEV sequential gearbox to destructive vibrations, premature gear wear, and ultimately, a complete lock-up of the front axle in the middle of a rally stage or track day. Do not lose the benefit of months of mechanical preparation, and avoid damaging a transmission assembly worth thousands of euros for a simple missing adjustment part.

Absolute Reliability from the Official Renault Sport Catalogue - Part No. 7711162220

This precision component is not a standard washer or an aftermarket adaptation. It is the official genuine Renault Sport / Alpine Racing shimming washer developed specifically for the Clio R3 differential (Access, Maxi, and Evo competition versions). Manufactured from high-thermal-resistance steel treated against crushing, it retains its nominal thickness despite the monumental axial forces generated during flat-out gear changes. This reference 7711162220 is your assurance of restoring the exact operating tolerances recommended by the factory.

Frequently Asked Questions (FAQ) – Technical Answers for Your Assembly

Why is this shimming washer sold individually?

Every gearbox casing and final drive crown wheel has its own manufacturing tolerances. When reassembling your Clio R3 SADEV gearbox, measuring the play requires the use of one or more very specific thicknesses. Providing this component sold individually allows you to order only the exact quantity needed for your metrology, without having to buy an unnecessary full kit.

How can I validate compatibility with my performance vehicle?

This part is exclusively dedicated to the Clio R3 SADEV differential under part number 7711162220. If your search concerns another model in the range (for instance, the Renault Mégane 4 RS, for which 2 different spark plug models exist depending on the year), caution is advised.
