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 lockspecially made for our surge hitch as well as a stem set bolt lock. You can check those out here: https://shockerhitch.com/product/sl-gooseneck-coupler-set-bolt-locks/
Can you really install the Gooseneck Surge in a couple of minutes? Yes check out the install 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.
