Roll Restrictor

5
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

Brilliant piece!

The item arrived beautifully packed and the quality overall is awesome. Mountune service is top, answered my few questions really quick and had it installed in my car few days ago. It does vibrate a little more in idle but its just that small negative point, the rest is all positive. The car improves ridiculously, driving experience is so much better with this mod. I didnt expect so much difference, really very happy. Worth every cent!

Brilliant!

Literally had this swapped out in 30 mins. Unlike the ST, the Zetec S/1.0 Ecoboost doesn’t have the exhaust bracket to contend with so is just 4 bolts. Driving feel is so much better pulling off the line and should hold up better when I go for more power. Little bit harsher at the lights in terms of vibration but nothing that drastic. Really simple and satisfying mod!
