The e2™ hitch from Fastway Trailer Products uses trunnion-style spring arms that connect directly to the hitch head and rest securely on L brackets attached to your trailer frame. This setup helps distribute weight evenly and reduce sway while towing, giving you a smoother, safer ride. Each trunnion arm is made to fit a specific hitch size, so it’s important to double-check your model before ordering replacement bars. Whether you’re hauling a camper or utility trailer, proper fitment ensures your towing system performs the way it should.
