Saves Fuel: By using a gooseneck Surge Hitch, you may save as much as one mile per gallon. When we developed the Surge Hitch our intention was to give a smoother ride, period. We perfected that and never considered the other benefits. Customers using the Surge hitch started calling with reports of better fuel mileage. Claims of up to a mile per gallon are pretty normal. The question is why? Trucks manufactured over the past ten years or more have a very sophisticated on board computer. The computer senses a jerk or load increase and gives the engine more fuel. This process happens many times in a second. By reducing the jerks, the computer will give the engine less fuel. The other contributing factor is cruise control. If your trailer bucks the cruise control will increase speed. When the buck stops, the cruise control reduces speed. This sets up a cycle of accelerating and decelerating, again using more fuel. A Shocker Surge Hitch can reduce this effect and give you a much smoother ride. Replacement stem has 3 adjustment holes and the coupler extends 3″ forward from factory location or you can also order it 9″ forward for short bed pickup trucks.

Saves Money: By reducing trailer breakage on both the trailer and the trailer contents! The Shocker hitch absorbs the damaging forces experienced with a typical hard connection.
