Jeep JK Wrangler

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.

If you're comparing Dynatrac to the competition, you owe it to yourself to read this article: 10 Questions You Should Ask When Shopping for an Off-Road Axle

We recently introduced Dynatrac Axle Sets which take the guess work out of selecting the best set of axles for the way you use your Jeep Wrangler. Check them out by clicking here: Dynatrac Axle Sets.

We are also an authorized Mopar® and Dana dealer, and offer these axles for the Jeep JK:
