SADEV 3-4 Dog Ring Slider ST66 Gearbox - Renault Clio 2 Gr N

Don't Lose a Race Due to a Worn Dog Ring Slider on Your Clio 2 Gr N

The 3-4 dog ring slider is the heart of the kinematics of your SADEV ST66 sequential gearbox. In motorsport, ultra-fast gear changes generate intense stress. Maintaining this critical component when it shows signs of wear is exposing yourself directly to disastrous consequences.

The Consequences of a Faulty Dog Ring: Retirement Guaranteed

If you do not replace this SADEV F1903205 slider, you risk poor gear engagement. A dog ring with degraded teeth causes gear jumping or transmission lock-up during upshifts and downshifts between 3rd and 4th gear. You immediately lose control and speed, not to mention the risk of breaking the internal gear set (wheels and pinions). A single faulty part can lead to the costly retirement of your Clio 2 Gr N from the race.

“When should I change the dog ring slider on a SADEV gearbox?”

The replacement of the dog ring slider must be carried out at the first signs of difficulty in shifting gears or abnormal noise. On a SADEV ST66 gearbox in a Clio 2 Gr N, preventive maintenance is the only guarantee of performance. Reference F1903205 ensures a return to original operating precision.
