SADEV Input Shaft F9001003 - Renault Clio 2 X65 Cup

The SADEV F9001003 Input Shaft: The Heart of Your ST75 Gearbox

Ignoring wear on your input shaft means accepting the risk of total mechanical failure during a stage or on the track. In a Renault Clio 2 Cup (X65), the input shaft is the vital link that transmits engine power directly to your SADEV ST75 sequential gearbox. A scored, micro-cracked shaft or worn splines will inevitably lead to the destruction of associated gears and, in the worst-case scenario, the catastrophic explosion of the gearbox casing.

Why Preventive Replacement is an Economic Necessity

The cost of replacing a SADEV input shaft is negligible compared to a complete gearbox rebuild after a failure. By failing to replace this part during major overhauls, you risk losing:

• Reliability: Increased risk of engine/gearbox failure during violent downshifts.
• Investment: Cascading destruction of internal SADEV transmission components.
• Time: Prolonged downtime for your race car in the middle of the motorsport season.
