Differential Bearing Retaining Clip SB120 SADEV Clio R3 - 7711162216

The Critical Risk of a Neglected Differential Bearing Retaining Clip

In a racing transmission, even the slightest uncontrolled play leads to catastrophic consequences. Overlooking replacement or using a generic retaining ring instead of the genuine SADEV SB120 clip exposes you to an immediate danger: the displacement of the differential bearing in your Clio R3. Without this genuine part calibrated to endure the intense physical constraints of motorsport, the bearing will shift, causing shaft misalignment, total destruction of the SADEV sequential gearbox gears, and an forced retirement in the middle of a rally stage. Do not ruin your investments and your race weekends for the sake of a new retaining snap ring.

Certified Manufacturer Quality from Renault Sport - Part Number 7711162216

This safety component is not a simple standard circlip. This SB120 clip comes straight from the official Renault Sport / Alpine Racing catalogue for the Renault Clio R3 range (Access, Maxi, Evo). Manufactured from high-tensile mechanical steel with specific elasticity properties, it guarantees constant clamping tension inside the differential groove, even under extreme gearbox oil operating temperatures. Part reference 7711162216 remains the only viable option to keep your transmission setup compliant with factory requirements.

Frequently Asked Questions (FAQ) – Gearbox Assembly Tips

Can the old SB120 clip be reused when replacing the bearing?

It is highly discouraged to reuse a retaining clip after removal. During expansion and extraction, the ring undergoes structural deformation that alters its original tension. Reassembling a used clip inside your SADEV differential reduces its retention capability, significantly increasing the risk of destructive mechanical play.

How do I ensure this part is fully compatible with my sports car?

This locking jonc is exclusively engineered for the Clio R3 SADEV differential under part number 7711162216. If you look after another performance car from the brand (such as the Renault Mégane 4 RS, which features 2 completely different spark plug models depending on the production year), this part will not fit. When in doubt, contact us with your vehicle identification number (VIN) for immediate confirmation.
