The mountune roll restrictor for the Puma ST and latest face-lifted Mk8.5 Fiesta ST reduces the amount of engine roll/movement during hard acceleration and gear-changes whilst maintaining an acceptable level of NVH (Noise, Vibration and Harshness) for every day use.
The EcoBoost engine found in the Puma and Fiesta ST generates a considerable amount of NVH due to its 3-cylinder architecture and as such, the OE roll restrictor has had to be designed in a way to minimise this harshness. Unfortunately, this also means the engine movement is considerable and this translates as unwanted wheel hop / tramping - which is unpleasant and detrimental to your car's overall performance.
Machined from T-6061 billet aluminium, the mountune roll restrictor features unique mixed shore-hardness polyurethane bushes to counteract unwanted NVH and minimise vibration as much as possible, whilst still providing the required restriction in engine movement to enhance performance.
High quality anodised billet aluminium body
Bespoke mixed shore-hardness polyurethane bushes

Increased performance, with the minimal increase in NVH possible
Please Note: Compatible with Puma ST and face-lift Fiesta ST only (pre-facelift Fiesta ST use a different mount)
