Currently, some work vehicles and/or off-road vehicles come from the manufacturer lacking tow hooks—or even a strong point on the rear bumper assembly and/or the chassis to install a tow hook. A non-limiting example of this sort of vehicle is the Toyota Tundra. It is highly desirable for such a vehicle to be able to be towed by another vehicle and/or have connection points for recovery from stuck in a natural hazard like mud or water. A novel and improved sway bar bushing bracket with a tow hook design is disclosed. In particular, the manufacturer-installed sway bar bushing bracket may be replaced with a reinforced sway bar bushing bracket with an integrated tow hook that may serve as a more robust sway bar bushing bracket, as well as providing a strong connection point with a tow hook.
