🧾 Overview
The TeraFlex Wrangler JK Alpha HD Adjustable Spare Tire Mount Kit (5x5 Bolt Pattern) is the industry-leading solution for securely carrying larger spare tires on your Jeep Wrangler JK. First unveiled at SEMA 2012, this system quickly became Chrysler’s #1 preferred spare tire carrier solution, setting the benchmark that competitors spent years trying—and failing—to match.
Engineered to handle the demands of aggressive off-road use, the Alpha HD Adjustable Spare Tire Mount Kit is designed to support up to a 35-inch spare tire when used on its own, and up to a 37-inch spare when paired with the Alpha HD Hinged Spare Tire Carrier (sold separately). Built from CNC laser-cut, heavily gusseted steel, this mount ensures your spare stays secure over rugged terrain without compromising tailgate function.
Complete adjustability allows precise vertical, fore, and aft positioning, ensuring proper tire clearance, weight distribution, and compatibility with various wheel offsets. Whether used as a standalone upgrade or as part of the full Alpha HD system, this mount delivers unmatched strength, durability, and trail-proven reliability.
