Building a Dynatrac Pro Rock 60 Front Axle

When you need to have absolute confidence in the quality of your axles and performance you expect them to deliver on the trail, no other company can give you this assurance other than Dynatrac and with their Pro Rock 60.  Made 100% here in the United States, the Pro Rock 60 has been engineered entirely with new off the shelf components that are designed to work flawlessly together and without the need to use recycled, refurbished or salvaged parts from older used axles.  Of course, the Pro Rock 60 is also the only axle with a profiled differential that offers well over an inch of ground clearance.  And, to top it off, Dynatrac is the only company that I know of that offers a “no-fault” warranty so long as you properly service and maintain your axles.

Needless to say, when it came time for us to upgrade the front axle in our Jeep JK Wrangler, there was no question what axle we would be getting.  And, fortunately for us, Dynatrac was kind enough to invite us down to their manufacturing facility in Huntington Beach, CA and watch the expert building of our Pro Rock 60 front axle from start to finish and after watching this short video, you’ll get to see why you will want one too!
