Mod Mafia tested the ARB CKMTA12 Twin Air Compressor for about 6 months before offering it for sale with this mount. This compressor (the 24v version) was tested in HMMWVs with success. It has two small compressors built into one so they run independently, just like having a built-in spare. It works really well, it’s quieter, faster, readily available, and much cheaper than a factory replacement. This mount connects to the stock rubber isolated mounting system. The compressor is available from us as well.
Mount is made of flat plate and is powder coated. The mount comes with mounting hardware, but does not come with hose or hose fittings. When you buy the ARB it comes with wire harness to complete the setup.
We tested a stock CTIS system with Cepek lines on Cepek wheels and 42″ Goodyear Kevlars. Followed by mounting on a truck with the ARB unit.. Trucks were of similar weight. The test were done with in 2 hrs of each other and ambient temp was about the same. Both trucks were running.
Stock compressor 20psi – 30psi (all 4 tires) : 10:51 min
ARB compressor 20psi – 30psi (all 4 tires) : 4:28 min
About 59% quicker!
– 20-30 psi test was chooses because of normal offroad pressure of 18-20 psi and on road drive around 30-32 psi
– 20psi and 30psi are easily read on the CTIS gauge
– smaller tires would air up quicker
The current mount fits 1999- 2004 trucks. It works on body lifted and stock height trucks. We are testing a 1995 soon and will keep you posted!
