3 Ways to Save $300

For a limited time, you can save $300 on a ProRock 44™, Trail Leader Axle Package™ or Serious Performance Axle Set™ for a Jeep Wrangler JK. We’re offering a $300 discount on our US-made JK44 chromoly 1350 axleshaft kit when purchased with a ProRock 44 or one of these two axle packages.

The front Dynatrac JK44 Axleshafts are made from high-strength 4340 chromoly. These 30-spline shafts come with 1350 U-joints, and are a direct fit to retain the factory wheel hub. They fit in both Dana 44 and Dynatrac ProRock 44 axles without any modification to the housings. The JK44 Axleshafts only fit non-Rubicon models, and will not fit in housings that use the factory Rubicon Tru-Lok locker.
