Is is too loud to mount in the cab area?** A: Here is a video I uploaded onto youtube. The compressor is mounted to a piece of 3/4" partical board (I still need to carpet it), which is mounted to some 1"x1"x1/8" angle steel, which I sandwich clamped onto my Garvin Wilderness interior rack in my 2015 Xterra which the legs were wrapped with a few wraps of "F4" or "self fusing tape" as found here on Amazon. The prevents damaging the finish on the legs, and provides another layer of vibration and noise dampening. Please note, I did not rehearse the recording so I say a few mistakes here or there, but you will get the point. https://www.youtube.com/watch?v=TVDWN7hc_Fk **Q: Does the Air Compressor contains the mounting clamp, backing plate, pressure switch, wire loom and all the mounting hardware? or just the compressor?** A: I cannot believe Amazon and ARB have not jumped on the fact that they do NOT list "what's in the box"! Shame on Amazon!Check the ARB website.It does indeed come with all you listed above except I am not sure if it has the mounting clamp or backing plate. I bought mine as a replacement for the same unit after 7 years of service. I did not need anything except the compressor. Good luck. **Q: Simple question: Can you run front and rear lockers with this compressor?** A: Yes you should be able to run both front and rear air lockers off this compressor. As well as air up tires!Thanks **Q: Will this fit and work mounted in the storage pocket under rear srorage on a 2 door 2008 jeep wrangler** A: i don't know, sorry! Most of the people install it under the hood of the engine, I have also seen it installed under the car near the gas tank, it is really small and you can place it anywhere since you control it from your cabin by a swich. if you are going to use it only to inflate the rubbers, it is fine anywhere, but if it is for use with blockers I recommend you under the engine hood. ## Frequently Bought Together - ARB CKMTA12 '12V' On-Board Twin High Performance Air Compressor, Ideal for Air Lockers Locking Differentials, Tire Inflator, Air Horn, Air Tools and Pneumatic Tools. - ARB 171302V2 Portable Tire Inflation Kit, Includes High-Temperature Air Hose 23 Foot and Redesigned Accessories Kit, Quick Fitting for Universal On Board Systems and Air Compressors - ARB 171503 Air Compressor Manifold Kit for Easy Installation of Two Air Lockers Solenoids on ARB CKMTA12 Air Compressor, Plug and Play Air Hose Kit for Tire Inflation --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/654952088-ckmta12-12v-on-board-twin-high-performance-air-compressor-ideal](https://www.desertcart.co.za/products/654952088-ckmta12-12v-on-board-twin-high-performance-air-compressor-ideal) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-07*
