The Spartacus HD Tire Carrier Hinge Casting for JL provides the ultimate in strength and stability for mounting your oversized wheel and tire. Functionally designed to manage the amplified force and vibrations produced during extreme off-road conditions. The precision die-cast aluminum Hinge Casting provides maximum strength without the excess weight of steel. The one-piece design hinge casting is a complete replacement for the factory tailgate hinges, creating a structurally stable link between the tailgate and the body, resulting in smooth one-handed access to the rear cargo area. This, in combination with forged steel hinge brackets and hardened steel pins, results in far superior load capacity than the factory tailgate hinges, thereby effectively reducing wear and increasing longevity. Compatible with OE and most aftermarket rear bumpers and installs with no drilling required. Recommended pairing with Spartacus HD Tire Carrier Wheel Mount (P/N 11546.57) for the optimum carrying capacity. Patent Pending.
