🧾 Overview
The TeraFlex Alpha HD Hinged Spare Tire Carrier Kit for Jeep Wrangler JK & JK Unlimited is a heavy-duty spare tire carrier system designed to support oversized spare tires while eliminating stress on the factory tailgate. The carrier mounts directly to the factory tailgate hinge locations, allowing the weight of the spare tire to be distributed into the vehicle body structure rather than the tailgate itself.
Designed to accommodate up to a 37-inch spare tire, the Alpha HD system provides smooth, single-motion access to the rear cargo area while maintaining durability for off-road use. Internal gussets and body bracing work with the factory JK structure to improve strength and long-term reliability when carrying larger tires.
The carrier also includes provisions for mounting additional off-road accessories such as recovery equipment and fluid containers, making it suitable for trail-focused builds that require added utility.
