Tested and ready for the long haul, the tow hitch receiver is available in two versions. The Class III hitch, designed for color-keyed bumpers, has a 5,000-lb. towing capacity and uses a 4-pin wire harness. For big towing jobs, a Class IV hitch, for Tundras with steel bumpers, boasts an 8,000-lb. towing capacity and uses a 7-pin harness. Both hitches have dual-layer paint to help withstand the elements.
Before towing, confirm your vehicle and trailer are compatible, hooked up and loaded properly and that you have any necessary additional equipment. Do not exceed any Weight Ratings and follow all instructions in your Owner’s Manual. The maximum you can tow depends on the total weight of any cargo, occupants and available equipment (calculated with the new SAE J2807 method).
