***Started as a OBA system thread but evolved so decided to make this a comprehensive build thread***
I know there are probably a lot of posts on OBA systems, but figured I'd share mine to offer up different ideas and help others who are contemplating doing their own.
First obstacle was debating where to mount the compressor. My initial thought was to mount in the Rambox but I wanted to utilize that space for recovery gear and other necessities. I ultimately settled on mounting in the engine compartment, it also was easier to wire up the solenoids for the air suspension.
There are 3 daisy chain solenoids (controlled via Switchpro in the cab). Two are for inflate (driver/passenger) and the third in the deflate (all 3 solenoids open up to exhaust the air through this one). The manifold also has two connections for front and rear air couplers.
For the front coupler I had to fabricate a bracket so I could mount in the area for the clutch access without interfering with the clutch itself
For the rear coupler i mounted in the area where the trailer tpms would have been
for air suspension I settled on the Airlift 5000 and Daystar cradles. Im not a fan of 90deg "sharp angles" anywhere near the tires (even though the likelyhood of it hitting is minimal), I considered it cheap insurance so I ended up modifying the mounts a bit.
passenger side with main airline routing
Cheers!!
