Chrysler's #1 preferred spare tire carrier!

In addition to engineering world-class premium suspension systems, TeraFlex has set the standard for Jeep Wrangler and Wrangler Unlimited accessories with innovative products such as the JK: Alpha HD Hinged Spare Tire Carrier & Alpha HD Adjustable Spare Tire Mount Kit. First shown at the 2012 SEMA Show, it quickly became the most popular tire carrier in the industry!

Not only did it leave our competitors’ heads spinning, but it inspired them to “develop” their own hinged spare tire carrier. It took them nearly five years to produce an inferior product lacking many of the features of our Alpha HD Spare Tire Carrier & Mount Kit.

Designed to accommodate up to a 37” 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.

I have had the Teraflex hinged carrier on my jeep for about a year, it has been holding a big heavy 37 with a steal wheel. This hinge has had no problems holding the weight and my tail gate has stayed perfectly aligned. Great product!
