Bracket Kit for Under Seat Mounting an ARB Twin Compressor

Grimm OffRoad’s compact mounting bracket kit solidly mounts ARB's Twin Air under the front seat of your 2018-2023 Wrangler JL, 2018-2023 JLU, or 2020-2023 Gladiator JT. This is the most functional and integrated kit on the market. The included bulkhead and wiring harness allows convenient access to the on/off switch and air chuck to the side of the front seat. By keeping the compressor inside the cab, it is kept away from the elements.

Includes Durable Steel Brackets, Air Line, and Wiring

The Grimm OffRoad bracket kit includes four steel brackets, 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 bracket houses the compressor itself, while two of the smaller brackets locate the compressor for installation and the last bracket mounts the switch and air coupling. Each bracket kit comes with all the necessary fittings, hardware, and instructions you need to get it installed in your Jeep.


  • Easy to access air for airing up tires or setting up air lockers

  • All brackets, fittings, and hardware required for installation are included
  • Mounts ARB Twin Compressor under the front seat away from the elements

Fitment Notes:
  • This bracket kit is only compatible out of the box with ARB's Twin Air Compressor (ARB Part# CKMTA12). We cannot guarantee the fitment of other air compressor systems.
  • Compatible with Diesel, 392, and 4XE models where the ARB Twin Compressor cannot be mounted in the engine bay.

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!
