The hidden risk of a worn or non-compliant engine mount bolt
During every acceleration and braking maneuver, your engine undergoes significant rocking motion. The mounting bolt connecting the anti-torque support to the gearbox endures colossal shearing forces. By reusing a stretched bolt or installing a standard non-certified fastener, you risk a sudden snap under full load.
A failure at this level leads to immediate excessive engine tilt, which can cause irreversible damage to the gearbox linkage, driveshafts, or even puncture the radiator. Failing to replace this bolt during maintenance is a compromise on the safety of your performance vehicle.
Genuine Renault parts for maximum reliability
The original lower engine mount bolt (OEM ref) is the only one capable of handling the required torque without the risk of premature plastic deformation. Whether you drive a Clio 2 RS (Phase 1, 2, 3, or Jean Ragnotti) or a Twingo 2 RS, this part ensures the optimal rigidity of your powertrain.
Vehicle compatibility and racing applications
This bolt is the factory standard used for maintenance and chassis optimization on the following models:
- Renault Clio 2 RS (172, 182hp) and Group N rally variants.
- Renault Twingo 2 RS (133hp) and Twingo R1 race versions.
