Designed to accommodate up to a 40” tire mounted on an 8-lug wheel, the TeraFlex JL: Alpha HD Hinged Spare Tire Carrier (NOT INCLUDED) and Alpha HD Adjustable Spare Tire Mount (INCLUDED) and Alpha HD 8-Lug Spare Tire Mount Adapter Kit (INCLUDED) will secure your full-size spare tire over the most extreme trails and rugged terrain.

The Tire Mount can support the additional weight of a full-size spare tire by securely mounting the tire to the Tire Carrier and tailgate.

Complete adjustability includes vertical as well as fore and aft adjustments. The Alpha HD Adjustable Spare Tire Mount Kit includes a quick-release 3rd Brake Light Mount and billet aluminum Rearview Camera Mount. The heavily gusseted Tire Mount is formed and welded from CNC laser cut steel for superior strength. Also includes our Alpha HD 8-Lug Spare Tire Mount Adapter Kit to mount an 8x6.5” spare tire and wheel combo to the Tire Mount.
