Bracket Kit for Engine Bay Mounting an ARB Twin Compressor

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.

Includes Durable Steel Brackets, Lines, and Wiring

The Grimm OffRoad bracket kit includes four steel brackets, a new air line and fittings, and a wiring extender that connects to the compressor's standard harness. Each bracket is made out of 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.

Was looking for something specific- gave them a call and was able to order it up, even though it was not on the website.

Boyfriend and I both have a set of the 2.5’ whips for our jeeps and use them every chance we get. They look for show and work even better for light in camp and on the trails. They bolt up similar to a radio antenna and have a quick release feature that we have never seen before but absolutely love. Definitely top 5 favorite accessories we’ve bought for our jeeps, and customer service is just as great as their products!
