This innovative solution provides a full mounting system for your spare tire, while completely eliminating all stress on the OEM tailgate. The factory-installed tailgate on the 2021+ Bronco, weighing a mere 27 pounds, is burdened with supporting a tire and wheel combination that weighs 93 pounds (with Sasquatch package), putting it at risk of wear and tear and potential damage.This creates a vulnerable situation for the tailgate, especially when larger tires are added. With the TC3-M1, you can have peace of mind knowing that your spare tire is securely mounted and your tailgate is free from unnecessary stress.
