I do have an option for you but we don't offer any inner tube square gooseneck couplers which measure 3-1/2" x 3-1/2" as this is not a standard size. That said, what you can do is install a new outer tube and inner tube of…

If the coupler will not adjust be sure that the set screw (shown in the linked photo) has been loosened to allow the coupler to move. If the set screw has been loosened and the unit will not adjust try applying a product like PB Blaster or WD40 to…

In regards to the Ram Gooseneck Coupler part #GCSQ-25008, the main things you need to know are the size and weight capacity. The outer tube which gets welded to the tongue of the trailer is 4-1/2" x 4-1/2". The inner tube which is…

There is not a wiring diagram for the Hopkins Trailer Connector Adapter - 7-Pole Round Pin to 7-Pole RV #HM47425 but I have added a photo showing the functions of a 7-pin round and 7-way RV blade style, which is what this adapter was intended for.…

The Never Fail Bushings like part #TRBU11566 and the Bronze Bushings like part #D014-077-00 are designed for 1-3/4" wide double eye leaf springs. There is not a version of these which are an upgrade over the factory nylon bushings for 2"…
