Regular Shocker Gooseneck Air Hitches offer feature a 3″ offset gooseneck coupler. There is also the option for a Shocker Gooseneck Air Hitch with a 9″ offset coupler. Offset coupler or extender coupler mean the same thing.
Offset Extender Coupler means the gooseneck coupler is moving the trailer further back from your pickup cab. An offset gooseneck coupler is changing the factory location of the gooseneck coupler. A 9″ offset would move the trailer 9″ further back and away from your pickup cab. This 9′ offset extender coupler option is needed if you need over 3″ to 9″ of extra cab clearance or if your are towing a gooseneck trailer with a short bed pickup (a bed that is under 6 foot in length). Pickups with a 6′ 9″ or 6′ 10″ bed generally do not need a 9″ offset to have proper cab clearance. The regular Shocker Gooseneck Air Hitch is generally ideal for most pickup trucks with 6′ 9″, 6′ 10″ & 8′ beds.
The Non Air gooseneck stems options can be ordered with either a standard gooseneck coupler, which does not have an offset and keeps the gooseneck coupler in the factory location or a 9″ offset extender coupler.
