The TeraFlex JK heavy duty hinged carrier kit is designed to support up to a 37” tire over the most extreme trails and obstacles, and provide easy and immediate access to the rear cargo area with a one-handed single action. The TeraFlex heavy duty hinged carrier spreads the load and weight of the tire to more than just one hinge point. Incorporating and using the factory tailgate hinge mounting points spread and separate the load as far apart as possible, resulting in maximum strength and durability. Dedicated tooling provides a cast A356. 2 T6 Aluminum main component.
