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 How soon will I get my hitch to 78580?

    Shipping times may vary from 3-5 days.

  3. 0 votes
    Q Why would you want to move the coupler 9” for a short bed pickup?

    For a short bed pickup, depending on the trailer being towed, that extra 9" of space would allow for more space in tighter corners, reducing the chance that the vehicle or trailer get damaged in the process.

  4. Do you make them for recessed ball on a flat bed truck?
  5. 0 votes
    Q Do you make them for recessed ball on a flat bed truck?

    Yes, our hitches do work with recessed balls. However the minimum size of the GN ball pocket needs to be at least 12" Wide x 12" Length. Also the ball can only be 2" down from the top of the bed to the top of the ball. Please see attached diagram.

Customer Reviews

  1. Love the product and Super easy to install.

    – Benjamin Taylor
  2. I’m still on the fence regarding this hitch. I believe I was just expecting too much out of the hitch and slightly disappointed. The one thing that I was hoping the hitch would do is eliminate some of the bucking while on concrete interstates, however I do believe it has improved somewhat but the gooseneck still is pretty rough while on rough roads.
    The one thing that I have noticed An improvement on is the tightness in my neck,
    After a long day of driving I was experiencing sore neck muscles and tightness in the muscles, after installing the hitch this has improved. I have only had the hitch for a week or so but have already logged about 5000 miles, I will need more time to have a full review but for now the three stars is the best I can do

    – Jimmy Frady
  3. Awesome design, awesome performance. 100% would recommend!

    – Chris
  4. Very noticeable improved less bumpy cab ride when towing deadhead with my goose neck trailor, thumbs up thus far

    – Glenn K
  5. Just installed. Still trying it out on a 1500 hundred mile trip. So far I can feel a smoother ride. I just need to play with my air bag pressure
    So far so good

    – Adrian
  6. 100 percent recommend this, The Construction and Engineering on this product is high quality, U.S.A made. And will definitely save your back and your equipment especially driving on concrete roads. The installation was easy. I did it alone but would recommend an extra set of hands.

    – Dan leisey

  9. So far I have only used it on my empty trailer. And I have 18 lbs in the air bag. But it’s a lot better.

    – Arthur Weir
  10. Very well built, heavy duty manufacturing. I have had it for a couple months now, and I’m not easy on it. Always hauling 20-30 k with my trailer.
    Great customer service.

    – Lowell E Forken
  11. I bought two of these units for a dump trailer, and a 40’ equipment trailer. There’s a night and day difference towing. It does take a little bit of time to get the pressure right, but it’s worth the investment.

    – Chris Baragar
  12. First off these guys offer a product I’ve only tried for a few weeks and I can be more pleased. Second their customer service is outstanding I made a mistake on my order and they were quick to fix it. Third it’s an American company I always support the hard working citizens of our great nation. I will continue to do business with them and you should as well.

    – Jeff
  20. Smooths out the ride immensely

    – Anonymous
  21. If you reading any of the reviews you obviously are dealing with some rough rides. Make this purchase! You will not regret it! AMAZING how much this improves the ride! I was getting jerked around like I was having a seizure sometimes and the first ride with this was beyond night and day! I’ll be getting another for my other gooseneck soon! Thanks!!
