SADEV Right Side Output Flange F1908351 (Gearbox Output) - ST75 Clio 3 Cup

The SADEV Right Output Flange F1908351: The Risk of a Failing ST75 Connection

The gearbox output flange is one of the most stressed parts, as it directly transmits the torque from the differential to the driveshaft of your Renault Clio 3 Cup. The right output flange F1908351 (or 7711160349) is designed for extreme stresses. If you use a worn or non-compliant part, you lose the sealing integrity and reliability of your ST75 sequential gearbox, jeopardizing your entire competition season.

The Inevitable Consequences of a Defective Output Flange:

Massive Gearbox Oil Leak and Insufficient Lubrication

The groove on the output flange ensures sealing with the gearbox output oil seal. If the bearing surface is scratched or if the flange has play, you lose essential gearbox oil. **Insufficient lubrication** of the differential and gears leads to overheating and rapid destruction of costly internal components. This is the most common cause of SADEV gearbox failure on the track.

Loss of Safety and Damage to the Lobro Driveshaft

The right output flange holds the Lobro driveshaft in place. A fatigued or deformed part generates dynamic play. You lose transmission precision and risk the driveshaft separating under maximum load. This scenario leads to driveshaft failure, and even irreversible damage to the gearbox casing of your Clio 3 X85 Cup.
