Grimm OffRoad’s compact mounting bracket kit solidly mounts ARB's Twin Air Compressor under the hood of your 2021 Ford Bronco. This is the most functional and integrated kit on the market. The included wiring harness allows convenient access to the on/off switch and air chuck on the right front fender and by tucking the air compressor vertically inside the inner fender, it is kept away from the elements while keeping the noise where it belongs: outside.

The Grimm OffRoad bracket kit includes four steel brackets, a new airline and fittings, and a wiring extender that connects to the compressor's standard harness. Each bracket is made from steel with a black powder coat finish to protect against corrosion. The larger brackets mount the compressor itself inside your Bronco's inner fender, while the smaller brackets support and stabilize the compressor. The compressor is oriented with the two inlet air filters at the top of the engine compartment. The kit comes with a new braided stainless-steel hose that runs to the included bulkhead fitting for attaching an air coupling like the one included in ARB's 171302 Pump Up Kit. Each kit comes with all the necessary fittings, hardware, and instructions you need to get it installed on your Bronco.
