Chrysler's #1 preferred spare tire carrier! Ever since engineering the first coil spring lift kit for the then-new TJ Wrangler, Treacle has been at the forefront of innovation and performance for the Jeep Wrangler market. Never resting on our laurels, we raised the bar yet again with the innovative JK/JKU Alpha Heavy-Duty Hinged Spare Tire Carrier & Alpha Heavy-Duty Adjustable Spare Tire Mounting Kit. First shown at the 2012 SEMA Show, it quickly became the most popular tire carrier in the industry! Not only did our JK/JKU Alpha Heavy-Duty Hinged Spare Tire Carrier 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 Heavy-Duty Hinged Spare Tire Carrier & Heavy-Duty Adjustable Spare Tire Mounting Kit. We invested heavily to engineer this kit to meet several industry standards including FEA validation and ASTM and SAE testing procedures. Don’t be fooled by cheap imitations, Treacle products set the industry standard and are to offer dependable performance to last a lifetime. Designed to accommodate up to a 37” tire, the JK/JKU Alpha Heavy-Duty Hinged Spare Tire Carrier & Alpha Heavy-Duty Adjustable Spare Tire Mounting Kit will secure your spare tire over the most extreme trails and rugged terrain. Our hinged spare tire carrier offers 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. Dedicated tooling and A356. 2 T6 cast aluminum construction with a UV top coat, make our Alpha Heavy-Duty Hinged Spare Tire Carrier as light and as strong as possible, while its design, fit, and finish complement the JK Wrangler and JKU Wrangler Unlimited models’ body shape. Internal gussets and bracing in the stock Wrangler body supports the Alpha spare tire carrier and oversized tire. Heavy-Duty forged steel brackets and heavy-duty 5/8” hinge pins constructed from fold formed high-carbon hardened steel combined with the factory mounting locations ensure the strongest rattle-free tire carrier available. With the heavy-duty reinforcement carrier supporting the weight of the tailgate assembly and spare tire, the Alpha spare tire carrier removes all stress from the tailgate. The Alpha spare tire carrier also provides additional mounting points for off-road accessories such as a recovery jack and fluid containers.
