I removed the plastic air box mount bracket and took that to a local fab shop along with the ARB mounting template. They were able to make a bracket for the dual compressor that used the same mounting holes and bolts in the body of the truck as the stock air box bracket. I no longer have that factory plastic mount in my truck, the compressor mount is in that place now. It was relatively cheap.
The only kit I could find you can buy to mount a compressor in the engine bay is from a TRX. After talking with the owner and exchanging photos and measurements, it seems like it would fit for Rebel trucks, and likely all 5th gen trucks that are using RamAir style intakes. I have not tried it though. You can buy a full kit with brackets, compressor, air tank, etc, or you can buy individual pieces. They mount the compressor above the fuse panel on the drivers side attaching to a heavy duty battery box they make. The compressor air tank ends up where the stock air box was. It seems like a quality piece of kit.
This is the ultimate onboard air system available for your TRX. Comes complete with the BrawlerFab fabricated battery box, BrawlerFab ARB Dual Compressor Mount with ARB Dual Compressor, BrawlerFab ARB Air Tank mount with 1-gallon ARB Air Tank, ARB Remote Hose Coupling Kit, ARB Air Hose, all...
