The TeraFlex JK: 3rd Brake Light Extension Bracket Kit solves many of the issues that arise when adding an aftermarket rear bumper, larger spare tire, spare tire carrier, and/or CB mount. This fully adjustable extension bracket kit allows you to adjust your stock 3rd brake light in 1” increments to accommodate up to a 38” tire. The extension bracket bolts to the factory spare tire mounting holes and reuses the factory 3rd brake light and wiring. Also features an integrated CB antenna mount. This kit is also compatible with the TeraFlex Alpha HD Hinged Spare Tire Carrier & Alpha HD Adjustable Spare Tire Mounting Kit.
