Focus ST & RS MK3 EcoBoost Mountune Billet Short Shift Arm

The mountune billet short-shift arm for the mk3 Focus RS & ST replaces the OE shift arm located on the gearbox.

Throw is reduced by 25%, allowing quick and more precise gear changes but thanks to the engineered counterweights a 500g weight saving has been achieved, without sacrificing any shift engagement or feel.


A shorter, crisper shifter throw provides a positive driving experience on the mk3 Focus RS & ST. After considerable evaluation and input, mountune engineers determined the optimum reduction for the mk3 Focus RS & ST shifter to be at 25%.

This amount allows an enhanced driving experience while maintaining an OE quality and feel, with minimal stress on the OE shift cables and components.
