SADEV 11-Tooth Secondary Shaft - Renault Clio 2 Gr.N ST66
En cours de réappro
Do not let a fragile transmission compromise your rally performance. This 11-tooth secondary shaft, specifically designed to mate with a 52-tooth crown wheel, is an official Renault Sport competition part manufactured by SADEV. Destined for the ST66 gearbox of the Renault Clio 2 Group N, this shaft (Ref: 7711129541 / F1903202) is the guarantor of reliable and precise torque transfer. As the exclusive SADEV distributor, Optimiz Access offers you the assurance of a certified genuine part to prevent any premature mechanical failure.
Secure your SADEV ST66 gearbox with the official 11-tooth secondary shaft
In motorsport, the secondary shaft is the backbone of your transmission. Using a part of doubtful origin or keeping a fatigued shaft in your Clio 2 RS Gr.N means accepting the risk of seeing your season come to a sudden halt due to gear failure. This 11-tooth shaft benefits from SADEV heat treatment and machining precision, essential for withstanding brutal gear changes and extreme torque loads.
Why the absence of a genuine SADEV shaft is a danger to your transmission?
Neglecting the quality of your final drive during a gearbox overhaul can have heavy financial consequences. Without the robustness of reference 7711129541, you expose yourself to:
- Tooth failure under heavy load, shooting metal debris throughout the entire gearbox.
- Accelerated wear of the 52-tooth crown wheel due to a lack of geometric compatibility.
- Loss of guiding precision, making your sequential gearbox less efficient and more fragile.
