Jeep JL / Gladiator Under Hood ARB Twin/Single Compressor Mount
As of 04/23/25 the Under Hood ARB Twin/Single Compressor Mount is on backorder. We have them in production now. The design needed to be updated to be compatible with the new ARB Brushless compressors. Sorry for the delay! We should have the mounts in approx 3-5 weeks.
Jeep has stopped including the engine cover on new 2022+ Jeeps. Since the engine cover is not included the bracket to hold the cover has also been deleted and not included. If you did not receive an engine cover (started with some 2022 models and up) you may not have the required engine bracket needed for the UnderHood mount to work. See photos for a photo of the required bracket. Front Engine Cover Bracket Part Number (5281948AB)
Fits Jeep Gladiator & Jeep JL with 3.6L Engine ONLY. Does not fit the 3.6L eTorque, 2.0, Diesel or V8 engines.
Designed to mount the ARB Twin or Single Compressor, model #s CKMA12 & CKMTA12. Included with the kit are: Compressor mounting plate, dual air chuck / rocker switch plate and mounting hardware. The compressor plate also includes small slots along both sides for zip ties once you have your airlines and wiring setup. We recommend using an adhesive heat shield on the bottom of the compressor mounting plate to help block radiant heat from the compressor. Heat shield NOT included.
Removal of the plastic engine cover is required to use this mount. There is a VERY slight amount of contact with the hood liner from a corner of the black casing of the compressor when using the ARB Twin on Rubicon models.
Optional "Air Kit" options available:
- "No Air Kit Needed" - includes compressor mounting plate, small front plate for air couplers and switch and mounting hardware. No air lines, fittings or air couplers are included in this kit.
- "Single Air Coupler Kit"- +$54.99 - includes compressor mounting plate, small front plate for air couplers and switch, mounting hardware, one 20" stainless air line, one ARB 90° air fitting and one ARB JIC-4 Air Coupler to mount on the front small plate of the compressor mount.
- "Dual Air Coupler Kit"- +$82.99 - includes compressor mounting plate, small front plate for air couplers and switch, mounting hardware, two 20" stainless air lines, one brass 3-way tee air fitting and two ARB JIC-4 Air Couplers to mount on the front small plate of the compressor mount.
- "ARB Manifold Kit" - +$129.99 - includes compressor mounting plate, mounting hardware, ARB Manifold kit, one 20" stainless air line, two ARB 90° air fittings, one 90° brass NPT fitting and one ARB 1/4" NPT Air Coupler. The small front plate is omitted from this kit as the manifold is mounted in that same location.

UnderHood Remote Air Filter / Dual Air Chuck Plate
UnderHood Remote Rocker Switch / Air Chuck Plate - Short
UnderHood Remote Rocker Switch / Air Chuck Plate - Long
Mount is 1/8" 5052 powder coated aluminum for superior corrosion resistance. Stainless steel mounting hardware included. No drilling required.

Let customers speak for us
The product is good quality
Thank you from Montreal, Quebec
In my opinion ARB is simply the best onboard compressor made including adapters and air lines
I already have one on the left side. This is for the right. Haven't installed it yet but I'm positive it will fit just fine.
Excellent fit and finish. Amazing customer service. What other company can you call and speak for 20 minutes to the owner about their products? This business is top class. I will certainly continue to spend my hard earned money with 813!
Super helpful support from Jeremy, and a great product that I'm pleased with. Thank you!
My accessory plate arrived quickly. It's top-quality; well manufactured and finished. It was well packaged to arrive in perfect condition. Now to drill some holes in it to mount my Garmin Power Switch!
Fit my 2024 Gladiator perfectly. Install took 15 minutes. Support prior to purchase was prompt and friendly. I do wish the mounting bolts were black like the panel (instead of nickel) but I’m not going to ding it a star - I’ll just chalk that up to my own OCD.
Great under seat mount. Am using it for the new brushless compressor and all works well. Great bang for the buck.
Fit and finish was great, came with high quality hardware, and paired great with a compressor mount for a full in cab air solution. 10/10
813 Fabrications truly never disappoints! Every product I’ve received from them has been top-quality, built with precision, and clearly made to last. But what really sets them apart is the incredible support and service behind the scenes. The team is responsive, knowledgeable, and genuinely passionate about what they do—something that’s becoming rare these days. It’s clear they take pride in their work, and it shows in every detail. Thank you, 813, for consistently going above and beyond.
This kit was easy to install and the quality is top notch! I will definitely keep 813 fabrication in mind for other upgrades.
I couldn’t be happier with the RotopaX mount I picked up from 813 Fabrications for my Alu-Cab Canopy Camper. The craftsmanship is top-tier — solid welds, perfect fit, and it looks like it was made by Alu-Cab themselves. It mounted up flawlessly and holds the RotopaX tanks snug and secure, even through rough off-road terrain.
What really sets 813 Fabrications apart is the attention to detail. You can tell these guys know overlanding gear and understand what real users need. The powder coat finish is rugged and clean, and everything about it feels purpose-built, not an afterthought.
Shipping was fast, and customer service was responsive and helpful. I had a couple of questions before ordering, and they got back to me quickly with answers and advice.
If you’re running an Alu-Cab Canopy Camper and want to add RotopaX fuel or water storage, this is the mount to get. 813 Fabrications has earned a permanent spot on my go-to gear list. Highly recommended.
I was looking for a bracket to use under the driver seat so my ARB compressor could breathe cool air. The plan is to mount this bracket on my under seat storage safe and run the two intake lines back over to the compressor under the passenger seat.
All the shipment was a little bit longer than I had hoped. They did contact me and said they were getting my order together and there was a little issue with packing. But it got here earlier than they had said for the later date. Also, the locks weren't working correctly so within 4 days I had a brand new set of locks that actually didn't fall apart. Communication was awesome and this is a very good product.
