SADEV 15-Tooth Secondary Shaft (15/58) - ST75 Gearbox - Renault Clio 3 Cup

Do Not Compromise the Drivetrain: The Importance of the SADEV 15-Tooth Secondary Shaft

The SADEV ST75 sequential gearbox in your Renault Clio 3 Cup is a precision mechanism. The 15-tooth secondary shaft is directly linked to the 15/58 final drive and plays a crucial role in transmitting torque to the wheels. Opting for a non-conforming or fatigued part means exposing yourself to irreversible performance degradation of your sports vehicle.

The Risks Incurred Without a Quality Secondary Shaft:

Definitive Loss of Best Practice and Homologation

Using a worn or damaged secondary shaft for your Clio 3 X85 Cup leads to improper meshing with the 58-tooth crownwheel and the pinion. You lose the precision and efficiency of the SADEV components, which can impact your vehicle's homologation if you are competing. This is also a risk of **losing the mechanical safety** essential at high speed.

Irreversible Consequential Damage to the ST75 Gearbox

Wear on the 15-tooth secondary shaft generates abnormal friction and shocks. You lose the protection of other transmission elements: the bearings are severely strained, and the crownwheel can be eroded. The cost of a preventive replacement is always significantly lower than that of a complete ST75 gearbox repair following an on-track failure.
