  1. Take a vertical measurement from the bottom of the ball coupler tube to the bottom of the trailer frame sleeve. This dimension will be used to set the Shocker Gooseneck Surge Trailer Hitch
  2. Remove pins or loosen locking bolts on the trailer frame sleeve, and remove the existing coupler tube.
  3. Slide Gooseneck Surge Shocker Hitch insert tube inside the trailer frame sleeve with the air bag toward the rear of trailer.
  4. Hold or support Shocker at vertical measurement noted in Step #1. This should duplicate the previous ride height of the trailer. Shockerhitch must be properly aligned, (parallel with trailer), to maximize its benefits. Note: If your trailer coupler tube is equipped with a pin or pins, the correct pin location must be marked in the Shockerhitch insert tube and have a qualified machine shop drill / machine the pin holes.
  5. Torque locking bolts to your trailer manufacturers’ recommended specifications. A spacer kit is available for some applications.
  6. Lubricate: Oil the coupler shaft, grease coupling ball socket, and grease the hitch ball to REDUCE WEAR AND IMPROVE SHOCKER ACTION. Main pivot grease zerk should be greased periodically for maximum bushing life. ( Simply, you cannot over-grease it! )
  7. Hook up the trailer by simply lowering the coupler onto the ball. (Handle will snap open & shut automatically). To release trailer: Pull handle up and hold while raising trailer.

Answers to Frequently Asked Questions on the Gooseneck Surge

How do I know the Gooseneck surge with fit my gooseneck trailer? There are two things you need to know. What kind of stem your gooseneck trailer has and what kind of ball your pickup has. You can also find the hitch you need by using our Gooseneck Trailer MFG guide.

What is the Gooseneck surge tow rating?  30,000 lbs towing capacity with Shift Lock coupler for 2-5/16″ ball  / 7,000 lbs tongue weight & 40,000 lbs towing capacity with 40K goose air with Shift Lock coupler for 3″ ball. With a 30k Shift Lock coupler its 30,000 lbs towing capacity & 7,000 lbs tongue weight.

How long will the airbag last? Our air spring bags are an industrial bag and will last for years and years. They are similar to truck airbags but have been beefed up internally for our towing applications.

Is there a way to lock the Gooseneck coupler? Yes, we do carry a gooseneck coupler lock specially made for our surge hitch as well as a stem set bolt lock. You can check those out here:

Can you really install the Gooseneck Surge in a couple of minutes? Yes check out the install video.

How much air do I put in the gooseneck surge air hitch?  See air pressure video.

What do your mean when you say straight or angled / slotted pin holes?  We are wondering if your gooseneck stem has holes that are straight across OR if it is slightly angled 10-30 degrees, where the stem hitch pin is off set or at an angle. Below is a picture of an angled stem, which we would use a stem with slotted holes to fit this angled pin. See our gooseneck stem selection guide.

Will it work with my flat bed pickup with recessed in a flatbed pocket? Yes, see install tab and fitment guide for recessed ball.

If I Order a gooseneck surge air hitch & coupler, what all comes in the box? Includes a complete replacement gooseneck stem, surge air hitch system & coupler along with clear-cut installation instructions.

How long will it hold air? This is a sealed air system that will hold air for weeks or months. If you haul the same trailer with the same load weight, it should be good for quite some time.

How strong is the center pivot bolt?  The main pivot bolt with grease zerk, or center pivot bolt, used on the gooseneck hitch, is a custom made 1 inch diameter 1045 medium carbon steel bolt. Strategically heat treated to prevent wear and includes a machined grease passage for easy lubrication and maintenance. It should be noted that the yield strength of the 1.25″ pivot bolt exceeds the rating of the gooseneck hitch.

How often do I grease it? The grease does not just lube the pivot; it also keeps water and dirt out. You cannot over grease it, once every few months should do it.

How does the air ride work? The air shocker is like a teeter totter. One end is an air bag, a pivot in the middle, and a ball at the other end. This gives a “pillow” effect at the ball end.

How much does an Shocker gooseneck surge weigh? The Gooseneck Surge Air Hitch & Coupler weighs 95 to 100 lbs depending on the model.

    Q What function does this actually have
    A This offers the same function as our standard 30K coupler, the airbag acts as a shock absorber for the roadshock, bucking, jerking, surging, etc. that you may feel while towing a gooseneck. The 9" offset is for people who have short beds that have an issue with their turning radius while towing, keeps the hitch away from the back of the cab.

Customer Reviews

  1. Exactly as advertised. Easy to install. Made a 1000 mile trip two days after installation. Could feel the bumps the truck hit but nothing from the trailer. The only way you knew the trailer hit a bump was from the noise made by the ramps shifting.

    – Brian Goodman
  2. Just installed and did a short trip of 50 miles. So far noticed smoother ride and softer starts and stops.. Need to play around pressures a bit to get fine tuned. Started with 12.5 psi on my LQ horse trailer.. Plan to try 15 psi next. Happy with purchase so far. Came recommended from a friend who swears by his.

    – Joyce
  3. Came in 3 weeks ahead of schedule. Very well made and very solid. I really needed the set back of 9 inches. Definitely helps with the ride even smoothed out RR tracks!

    – Jim Manka
