Designed to accommodate up to a 40in tire, the TeraFlex Alpha HD Hinged Spare Tire Carrier and Alpha HD Adjustable Spare Tire Mount (NOT INCLUDED) will secure your full-size spare tire over the most extreme trails and rugged terrain. It also provides easy access to the rear cargo area in one smooth action. Using the factory tailgate hinge mounting points spreads the load of the spare tire over a larger area for maximum strength and durability. Internal gussets and bracing in the stock JL body supports the Alpha HD Hinged Spare Tire Carrier and oversized tire, which eliminates all stress from the tailgate. Compared to the JK piece, the new JL: Alpha HD Hinged Spare Tire Carrier spans nearly the width of the tailgate for better weight distribution. Additionally, the updated design features a one-piece, forged steel hinge that ties the top and bottom factory hinge locations together as well as additional vertical braces for increased strength. The Alpha HD Hinged Spare Tire Carrier also provides additional mounting points for off-road accessories such as a recovery jack and fluid containers.
