Roll Restrictor [Mk7 Fiesta 1.0 EcoBoost]

The mountune roll restrictor for the Fiesta 1.0 EcoBoost reduces the amount of engine roll/movement during hard acceleration and gear changing.

With a product such as this, care must be taken with the design and choice of materials, as a poor design can destroy the feel and driving experience of the car. With an extensive background working in the OEM market, mountune have the knowledge and engineering expertise to create a product which can reduce the engine movement by the desired amount, but with minimal effect to the NVH (Noise Vibration Harshness) level.

The mountune roll restrictor for the 3-cylinder EcoBoost is machined from high quality aluminum, and features a unique Powerflex polyurethane front, and large rear oval bushing with carefully positioned, elongated cut-out sections – to help minimise horizontal plane NVH.

The bonus of using polyurethane is that not only has it been engineered to give increased stiffness without causing excessive vibrations, it also doesn’t deteriorate like rubber does, so the service life of the component is greatly increased.

Kit features:

  • High quality anodised billet aluminum body
  • Bespoke Powerflex polyurethane bushes with elongated cut-outs
  • Reduction in engine movement 
  • Minimal effect on NVH

Please note: This is not compatible with Powershift transmission

INSTALLATION NOTE: The main RR bolts should be tightened to a torque value of 70Nm

    Short shift billet

    A little bit awkward to fit but well worth it

    No more clunking

    Install was straight forward. My clunk is gone. The engine vibration that translates to the car is almost not noticeable.
