Curt Long Trunnion Bar Weight Distribution Hitch

CURT Weight Distribution hitches come with a 2" x 2" shank and are compatible with class 3, 4 and most 5 trailer hitches, including Xtra Duty and Commercial Duty (2 1/2" replacement WD shank may be required), as well as some RV trailer hitches. While a weight distribution hitch will increase the gross trailer weight capacity of most trailer hitches, the vehicle's weight carrying capacity must be taken into consideration before towing a heavier trailer (NOTE: Never exceed the lowest weight capacity of any towing component).
