Dynatrac Trail Leader Axle Package™ for Jeep Wrangler JK
The Dynatrac Trail Leader Axle Package™ is engineered specifically for Jeep Wrangler JK owners who enjoy moderate off-roading and want dependable drivetrain strength after stepping up to 33–37 inch tires. This package delivers proven Dynatrac durability without unnecessary wheel changes or costly upgrades that are not required for this level of use.
Designed as a balanced solution, the Trail Leader Axle Package™ combines a fully assembled ProRock 44™ Unlimited front axle with critical rear Dana 44 upgrades, providing a significant strength increase while retaining factory compatibility where it matters most.
This package is intended for non-Rubicon Jeep Wrangler JK models only. Rubicon owners should consider alternative Dynatrac axle solutions.
