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.

You’ll never go back to the ‘old days’ of continual bumps, jerks, and vibrations. Join the list of satisfied customers that are using Shocker hitches. Order one today and get ready for your ultimate smooth towing experience the next time out.
Air Ride Hitch Technology: Shocker Air is designed with a built-in air bag for a smoother towing experience. Just add air depending on the weight of your trailer and it’s contents.
Simple Pivot Design: Uses a rocker arm pivot design which produces a front and back motion, much different than other cushion hitches on the market. Our design eliminates the need for parallel linkages, shock absorbers, torsion arms and other over engineered gadgets.
Improves Safety: By giving you improved control of your tow vehicle and trailer. The Gooseneck surge air hitch system allows for better control of your pickup and the trailer it is towing.
Shock Dampening Action: Shocker air hitch effectively absorbs the jerking, tugging and damaging forces experienced with a typical hard connection when towing trailers. There is no reason to beat yourself or your equipment up with a hard connection.
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. This greatly reduces the chances of breaking welds and doing other long term damage to your equipment as well as the valuable cargo you have inside the truck and trailer.
Provides Comfort: With a smoother ride! Travel a lot on concrete highways? No more jarring every time you cross a section divider. Your Shocker air hitch absorbs the thumps, bumps and jerks you feel when towing your gooseneck trailer.
