DESCRIPTION Specs. The JK HD Adjustable Tire Mount Kit from Teraflex is made to be used with the Teraflex JKHD Aluminum Hinged Tire Carrier, which you can buy separately or together as a set. Made from lightweight aluminum, this carrier allows single one-handed entry into the Jeep cargo area. It can be adjusted to fit up to a 37 inch tire, and completely eliminates those frustrating tailgate stresses and rattles. Made by one of the most trusted names in the industry, this is a kit you can count on. Construction. With threaded mounting holes for mounting accessories like fuel cans, recovery jack, and others, this is simple and easy to install. You use only common hand tools and no drilling is required. You'll appreciate the factory form fitting geometry and finish, plus the CAD-designed tooling that follows the exact compound curvature of the Jeep body. The result is a carrier with OEM appearance. There is no aftermarket bumper purchased required because this carrier works with both OE and aftermarket bumpers. Application. This kit fits 2007 - 2016 Wrangler JKs.
