Video Transcript for Buyers Products Fifth Wheel King Pin - Universal King Pin - 337BKPT809B Review

Speaker 1: Today we'll take a look at a Two Inch Forged SAE Trailer Kingpin. This trailer kingpin provides strength and reliability in coupling your fifth wheel. It's forged from AISI 8630 steel, and heat treated to maintain a hardness of 302-363BHN and 150,000 psi in ultimate strength. The kingpin has a half inch thick bolster plate. Again, constructed of forged steel construction; has a nice plain finish on it. The holes right here, take a measurement of those, straight across from one another.

They are separated apart on center by 6 3/4 inches. The overall diameter of this plate is eight inches. Here are the measurements I want to give you real quick. From very bottom to very top, so I'm gonna place a flat edge across the top and I'll measure up to that flat edge. That measures 4 1/2 inches.

From very bottom to the bottom of the top plate, so this base right here, so that's 3 13/16ths inches. This portion has a diameter measurement of 2 13/16ths inches. This portion right, edge to edge, has a diameter of two inches. Then edge to edge right here at the base is three inches in diameter. Again, nice durable steel construction and the product is made in the USA.

That's gonna do it for today's look at the Two Inch Forged SAE Trailer Kingpinm.

  • Troubleshooting Short King Pin on a 1972 5th Wheel Trailer
    It sounds like you have an older 5th wheel pin box and you need to either replace the king pin or replace the entire pin box. To replace the king pin you most likely would need a weld-on option like the Buyers # 337KP20038 which has a 3/8" bolster plate. If you would rather go with a bolt-on option then we do have part # 337BKPT809B but you need to make sure that you pin box is in excellent condition to ensure that this will hold up properly. We do carry replacement pin boxes as well...

  • Bolt Size Needed For Buyers Products 2 Inch Forged SAE Trailer King Pin 337BKPT809B
    The bolts do not come with the Buyers Products 2" Forged SAE Trailer King Pin with 1/2" Bolster Plate - Bolt On # 337BKPT809B. So I did check with the manufacturer, Buyers Products, and they told me the bolts needed to be 1 inch long x 1/2 inch. As far as procedure, there isn't one I can offer as it will differ depending on the application and is a project for professional fabricators. As for which is better, this bolt-on has the exact same specs as the weld-on # 337KP20050 king pin...

  • How Does Buyers Products BKPT809B Kingpin Install to Trailer
    I can see the tag in your picture and can tell that what you have is the Buyers Products King Pin part # 337BKPT809B. This is designed to be bolted to a recessed bolt plate on a trailer and once installed the nuts would be lower than the cut out area for the king pin so that they wouldn't drag. If your trailer does not have the needed plate you'd want to contact a welder in your area as they'd be able to help with that.

  • Are There Universal-Fit Replacement King Pins Available
    If you're wanting to only replace the king pin you'll need to measure the bolster plate hole and use a weld-on king pin like part # 337KP20050. This specific part has a 3" bolster hole diameter. As long as the bolster hole is large enough for the replacement and the pin box is still in good condition then you can have a qualified welder weld the new king pin on. If you'd prefer to just replace the entire pin box then we'll need to first determine the bolt pattern for your current pin...
