Jeep JK Wrangler
Dynatrac™ is no newcomer to the popular Jeep Wrangler JK market. We were the first manufacturer to develop an upgrade front axle – the ProRock 44™ – to replace the factory Dana 44. Our ProRock 44 is an affordable housing that is built for the tough demands of a modified JK that is used off-road.
Today, we offer bolt-in axles for the JK that will handle all types of off-roading, mild to extreme, with our Pro Series™ and our patented ProRock™ line of axles that deliver best-in-class ground clearance. No one else delivers the ground clearance, strength and durability of a Dynatrac axle.
