Check it out - In this short video clip, you will see two Jeep JK Wranglers that are similarly built, both running 37" Falken Wildpeak's and taking on the exact same line on the exact same obstacle only one is running a Dynatrac Pro Rock 60 front axle and the other is running a competing axle. See what happens for yourself. Dynatrac - Because clearance matters!

Pretty cool stuff. But what if the rock peaked on the other side of the differential? Does it do a pretty good job of shifting the weight to the groove?

even if you were to take on the rock at the lowest point of the the differential, a pro rock 60 it's still higher up than a Dana 44.

First of all.....flex is not important, coilovers only give a smoother ride, and Second, I have heard from some guys on PontiacAztec4x4.com that wheel really hard with stock Dana 30's on 42"s that the trail used in the video had a work crew in front of the jeeps placing rocks in the right places so the rigs running Dynatracs wouldn't get stuck. Nothing personal to the OP, know what I'm saying.......;)

But seriously, that actually is a great clip from the Holy Cross trail in CO. Pretty interesting picture of the Pontiac, because I was totally pulling the PontiacAztec4x4.com thing out my rear end. I never actually thought people modified one of the worst cars of all time :crazyeyes:

I image searched Google for "jacked up Pontiac Aztec" and "lifted Pontiac Aztec" and that is the only pic of one that came up, so I have to believe we are looking at the only one that has been offroad modded .......in the ENTIRE WORLD !
We are lucky just to have seen a picture of it. I would probably faint if I saw it in person. :icon_crazy:


Boy, we have really gotten off track here haven't we. Sorry WOL.

These are really cool when the "overlanders" start the vehicle, turn the heater on to warm up the tent, and the exhaust either kills them or the heat from the tailpipe lights the tent on fire.

:cheesy: And those silly overlander hats and clothing look fairly combustible, so I can see how that wouldn't work out for them...

Eddie, I hope you don't mind that I have cut/pasted this from Dynatrac's response to another forum member on the JK Forum. The gist of the question was "how does a shaved D60 stack up to a PR60?", Dynatrac's response below has come up in many threads in the past, but really is telling of why so many of us spend our hard earned money on a set of ProRock 60's.


Great video!! Thanks Eddie!


Regarding a shaved 60:
It's not just the lowest point of the PR60 that adds clearance. The entire housing is designed for maximum clearance everywhere below the axle tubes. We did this but yet increased the overall rigidity of the housing. By keeping the cover in the back it allowed us to improve strength across the top of the housing to prevent housing flex (and accompanying gear mesh issues). The top of the housing can be subjected to huge pressures especially during high speed desert type wheeling.

The clearance difference is even more pronounced when compared to a fabbed 9" housing.

The Dynatrac housing in blue is overlaid onto the green fabricated 9" custom housing.

Actually, I'm glad you posted that up as I was planning to do the same. :thumb:

I talked to jim yesterday to ask about how the prorock 60 measures up to a dana 44 and I think people would be amazed to see this...

2984

The Dynatrac ProRock60 in shown in grey and the blue represents a stock JK Dana 44. Both housings are aligned at axle CL and are also positioned at the same pinion angle for an apples to apples comparison. As you can see in this pic, the lowest point on both is the same only one is a BIG ProRock 60 that provides more overall ground clearance over the much smaller Dana 44. Of course, if that weren't enough, the ProRock 60 also has a much sleeker and smoother base with fewer obstructions such as the 2 ridges that a JK Dana 44 has that tends to catch on rocks.

There really is a HUGE difference between a ProRock 60 and anything that people try to compare to it and for me, that's what makes them worth every penny :yup:
