The hitch is exactly what I wanted and will be installed in the next day or so. I have had these same gooseneck hitches before and would not use anything else. Thanks to etrailer for their great service getting this to me in a very timely manner. 419197


Ask the Experts about this Auto Lock Gooseneck Trailer Coupler

  • Availabiltiy of a Gooseneck Coupler to Replace a Fifth Wheel King Pin On a Trailer Coupler
    We have the Gooseneck Coupler - 24K, Item # SM2516NP, that can be welded to a 4 inch square inner tube. This coupler does not come with the tube so you would have to remove the fifth wheel king pin from your coupler and weld the gooseneck coupler to the existing square tube or weld the coupler to another tube and install it after removing the existing coupler and inner tube. At this time we do not carry the replacement 4 inch square tubing for gooseneck hitches.

  • How To Replace Springs For Auto Lock Gooseneck Trailer Coupler LL2516ST
    I do have an option for you but the spring for the 28" - 38" Gooseneck Trailer Coupler - 24K - 4" Square part # LL2516ST is not available on it's own. The only way to replace the two springs is to replace the coupler with part # SM2516NP. However this part would need to be welded to a 4" inner tube that we do not carry at this time. It may be easier and more cost effective to just replace the whole coupler with part # LL2516ST.

  • Can Inner Leg And Crank Assembly Be Used For Gooseneck Jack On Trailer
    I called my contact at Auto lock and asked about the Gooseneck Trailer Coupler # LL2516ST. They told me that you cannot disassemble the jack to use just the inner leg and crank. I know you prefer not welding a new jack in place but I think that is your best option.

  • Coupler Lock Recommendation for Trailer with Gooseneck Coupler # LL2516ST
    Since there isn't a lock that's going to work great on the coupler of the # LL2516ST your best option is going to be to use a wheel lock to lock the trailer. This will allow you to secure by the wheel of the trailer instead which will be just as effective as a coupler lock. For that the Rack Em lock part # RA-25 would be a great option. I attached a review video for this lock for you to check out as well.

  • Replacement for Adjustable Gooseneck Trailer Coupler
    The inner tube for the Auto Lock Gooseneck Trailer Coupler # LL2516ST is not available by itself from the manufacturer. With this in mind if the screw on your existing coupler is frozen your best option will be to use the Auto Lock Coupler to completely replace it. This adjustable coupler has a height range of 28 to 38 inches and a towing capacity of 24,000 pounds.

  • Gooseneck Trailer Coupler Like # SM2516NP Is Difficult To Operate
    Since the # SM2516NP is a weld-on application I am not sure if it would be easy to just change out the coupler on your trailer. You may want to try some white lithium grease to see if that frees up the mechanism a bit and makes it easier to unhook the trailer. It is designed to allow you to move the lever to open the jaws and pull the vehicle out. If that does not help you may want to consider either replacing the coupler or the entire assembly with part # LL2516ST. This is designed...

  • Gooseneck Coupler Hitch Ball Locking Head
    Yes. The Gooseneck Coupler - 24K # SM2516NP will work on square tubes as well. You can see this application in the 28" - 38" Gooseneck Trailer Coupler - 24K - 4" Square # LL2516ST. I've attached a video that explains the functions.
