Convert-A-Ball Trailer Coupler - CG

Rubberneck hitch is a coupler designed for gooseneck trailers. Fully cushioned up and down, forward and back, and 360 degrees all ways. The rubberneck will take the shake, rattle and roll out of gooseneck towing.


  • Replaces standard gooseneck coupler - slides into existing 4" inner diameter outer tube on trailer
  • Cushioned with polyurethane for 360 degrees of protection - plus up-and-down cushioning
    • Acts as a shock absorber - less wear and tear on your equipment
    • Reduces bounce and rhythmic vibrations to give you a safer, smoother ride
    • Limits movement to a maximum of 3/4"
  • Equipped with fail-safe, positive-lock feature to increase hitch-coupling safety
  • Includes a steel extension handle that allows you to slide the bar to lock or unlock coupler from outside of the truck - no more crawling up into the truck bed to disengage coupler
  • Can be locked in transit or when parked - padlock sold separately
  • Constructed of powder coated steel with interior polyurethane cushion
  • Made in USA


  • Application: standard gooseneck trailers
    • Fits 2-5/16" gooseneck hitch balls
  • Towing capacity: 30,000 lbs
  • Tongue weight capacity: 2,000 lbs
  • Tube diameter: 4"
  • Tube height: 22"
  • Overall height: 25.94"
  • 2-Year limited warranty

I replaced the existing coupler on my 20' 14,0000# GVW flatbed trailer with this coupler. What a difference! I think it would be conservative to say that making this change has cut the jarring from the trailer to the tow vehicle easily in half. After buying the first one of these for my own use I ordered a second one for a conversion to a customer's trailer. What a simple fix for a very annoying problem! 31269
