SADEV 12-Tooth Secondary Shaft (7711129468) - Renault Clio 2 Gr N ST66 Gearbox

Do Not Sacrifice Your Power: SADEV 12-Tooth Secondary Shaft ST66 for Clio 2 Gr N

The secondary shaft is the backbone of your sequential gearbox. Choosing to keep a weakened shaft, even one that is slightly bent or micro-cracked, is accepting the risk of total destruction of your SADEV ST66 gearbox during maximum strain in a race. For your Renault Clio 2 Gr N, reliability means using reference 7711129468 / F19030201.

What You Lose with a Compromised Secondary Shaft:

• ❌ Catastrophic Failure: Under extreme engine torque, a faulty secondary shaft can snap, causing debris to scatter inside the casing and leading to the irreversible destruction of the entire gear cluster.
• ❌ Incorrect Final Drive: This shaft has 12 teeth and is designed to be paired with the 58-tooth crown wheel (7711129469). Using a non-compliant or deformed part would compromise the geometry and the efficiency of the final drive.
• ❌ Premature Bearing Wear: Abnormal stress on the secondary shaft induces excessive load on the bearings, leading to their premature failure and the need for an expensive overhaul.
