3 of my friends and myself installed a Viair OBA 450C kit (5gallon tank) and PRXB PacBrake on my 07 this weekend.

Best order I can...

The tank I did not use only 2.5 gallon


Removed elbow... maybe too 5minutes


Factory elbow next to new unit...



Installed Brake, took maybe 10min, there is a bracket on the exhaust and tranz and if removed you can move the pipe easily to align pipe to brake.



Rear tank mount, welded to crossmember infront of spare tire...


Front tank mount, welded to bottom of bed crossmember/support. Just in front of Carrier Bearing/drive shaft...


Front Air Chuck, also another at rear bumper on hitch...


Compressor Guage and switch... I DID NOT want it inside, so under the hood it went on the passenger side.

 

Brake all tightened up and air lines ran to it.



Completed air tank, Silver Steel Braid line goes to compressor, and pressure switch is in the front of the tank.


Rear of tank looking forward...



Compressor is mounted on top of the frame rail on the passenger side, I cannot hear it running with the motor on, I cant hear anything with the motor running actually. The brackets I made and still need paint but its been too wet and cold to paint.





Impressions:

With the PacBrake enguaged and not having a muffler the truck does sound much like a big rig when they use the Jake. I can hear the engine compression very clearly when enguaged, as well as the relief valve on the cylinder goes off. When in Tow/Haul mode and the brake on the truck slows very rapidly and controlled. I can hardly wait to yank the Jeep around !


AW

 

looks great, cant wait to do it to mine.

 

Nice write-up. Now I just need some more funds for mine.

 

Nice!

I bet that compressor works better than the tiny one that comes with the brake...

My compressor gets pretty warm inflating ATV tires.

 

Takes less than 6min to reach 150psi in the 5Gallon tank, and hardly gets warm. Im lovin it !
