Designed to accommodate up to a 37in tire, the Alpha HD Spare Tire Carrier & Mount Kit secures your 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 JK body supports the Alpha HD Hinged Spare Tire Carrier and oversized tire, which eliminates all stress from the tailgate. The Alpha HD Spare Tire Carrier also provides additional mounting points for off-road accessories such as a recovery jack and fluid containers. The Alpha HD Adjustable Spare Tire Mount Kit will support the additional weight of a full-size spare tire by securely mounting the tire to the Alpha HD Hinged Spare Tire Carrier and tailgate. Complete adjustability includes vertical as well as fore and aft adjustments. The heavily gusseted tire mount is formed and welded from CNC laser cut steel for superior strength. Although the Alpha HD Adjustable Spare Tire Mount Kit can be used alone, it has been designed to be installed in conjunction with the Alpha HD Hinged Spare Tire Carrier.
