Video Transcript for Buyers Products Fifth Wheel King Pin - Universal King Pin - 337KP20038 Review

Speaker 1: Now, we're gonna take a look at the two inch forged SAE Trailer King Pin with the 3/8 inch thick bolster plate. Now, this trailer King Pin will provide strength and reliability in coupling your fifth wheel. It is made of a forged steel construction. It's forged from AISI8630 Steel. It is heat treated to create and maintain a hardness of 302-363 BHN. It is 150,000 PSI in ultimate strength.

The bolster plate, up at the top here, the diameter on that, edge to edge, is right at eight inches. The bolster plate thickness is 3/8 of an inch. And then the bolster plate hole thickness, which is the portion right here, is three inches diameter. This part is made in the USA. The two inch measurement is the diameter right down here of your King Pin.

That should do it for the review on the Two Inch Forged SAE Trailer King Pin with the 3/8 inch thick bolter plate.

Absolutely the best service. We seem to be living in a world where vendors don't care and customer service has gone to the wayside. I thank God that there are still some vendors that take customer service above and beyond. Great job etrailer.

I installed the King Pin into a Goose Neck and customer is very satisfied. I liked the quality of the material the pin is made from. Welding using 1/8" E7018 was a snap!
