Truly a magnificent piece of engineering. Picked up one of these through Northridge assembled and it has been a real change to how I wheel and what obstacles I'm able to overcome.
Hello In October 2013 I got this D60 ProRock axle assembly for my JK's rear end and the D44 ProRock for the front end, I wheeled the combo on 37's at four Jeep Jamborees and a bunch of other off-roading and the combination was amazing! It was like a whole new Jeep, far from just calling it a mod or an upgrade...

A: Direct from the mfg's website, it stats "Dynatrac Heavy-Duty Raised Track Bar (not shown in photo)". That leads me to believe that it is the raised version.

A: We assemble them in house. We can set it up with 4.10's. You would need to call in to order it that way.
