The GrimmSpeed Lightweight Battery Mount in black for the 2013-2018 Ford Focus ST / RS replaces the factory battery battery mount with a lightweight aluminum unit. The OEM component is typically stamped steel that corrodes with age, the GrimmSpeed aluminum replacement reduces weight and eliminates the corrosion while adding a finished engine bay appearance.
DETAILS

- Lighter than OEM steel
- Eliminates corrosion vs OEM steel
- Direct bolt-on replacement
- Fitment: 2013-2018 Ford Focus ST / RS
The factory battery tie down or mount is stamped steel that starts rusting after a few years of moisture and road salt exposure. It becomes an eyesore in an otherwise clean engine bay. The GrimmSpeed aluminum replacement eliminates the corrosion potential entirely while reducing weight, a minor but genuine reduction at the battery location.
Installation is direct bolt-on at the factory mounting points. The black anodized finish resists the moisture and debris exposure of the battery area without degrading.
