Over five decades ago, Eaz-Lift became the first patented weight distributing system in North America. Designed with fewer parts, machine tapered round spring steel bars, and forged longer for a smoother ride with interchangeable bars that have positive latching action for operation. Eaz-lift has a broad selection of weight distributing hitches that include bolt-together ball mounts that are completely adjustable for changing ball heights with right and left hand sway control mounts. With or without bolt together adjustable shank.
