The TeraFlex Heavy Duty Hinged Carrier & Adjustable Tire Mount is designed to carry 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 single, factory style action unlike most aftermarket tire carriers. The tailgate reinforcement Kit 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. 5/8″ High-carbon Hardened Steel Pins connect the cast aluminum carrier to the HD forged hinges. Pre-installed brass bushings provide low frictions movement. The forged steel hinge brackets bolt to the factory reinforced hinge mounting points for superior strength. The hinge brackets provide support needed for the complete assembly. The HD Adjustable Tire Mounting kit allows fine tuning fore and aft spare tire position to keep it secured as close to the body as possible for maximum rear clearance. Multiple vertical mounting holes provide custom spare tire height to fit multiple rear bumper configurations and to keep center of gravity as low as possible.
