1st Gear Ratio SADEV Sequential Gearbox Clio R3 - 7711167240

The Cost of a Worn First Gear Ratio in Motorsport

In motorsport, the first gear is highly stressed during critical start phases and acceleration out of the tightest hairpins. Continuing to race with a 1st gear ratio showing signs of wear on the teeth or dog faces inside your SADEV sequential gearbox is an extremely risky gamble. Without this new genuine manufacturer gear, you expose yourself to gear pops, accelerated wear on surrounding components, and in the worst-case scenario, a tooth failure that would destroy the entire shaft assembly of your Renault Clio R3. Do not waste a full season's effort and avoid a transmission rebuild worth thousands of euros because of a neglected gear.

Frequently Asked Questions (FAQ) – SADEV Gearbox Overhaul Advice

When should the first gear ratio be replaced?

The replacement of the 1st gear pinion should be carried out as soon as a visual inspection shows signs of pitting on the teeth or abnormal rounding on the dog engagement teeth. In competition, anticipating this wear during off-season overhauls prevents catastrophic failures on track or stages.

Is this part number compatible with other sports vehicles from the brand?

No, this first gear ratio under part number 7711167240 is exclusively calibrated for the Clio R3 SADEV sequential gearbox. Precision is absolute in the performance world: for instance, two completely different spark plug models exist for the Renault Mégane 4 RS depending on its exact configuration year.
