Question:

I was wondering about the dimensions of a gooseneck coupler product number KPG5-R30IP. All dimensions are provided on the product page except the overall height of this part. Can you help me here?

Hey Jackson! The distance from the top of the tube down to the plate is 29". The distance from the top to the first bolt hole is 14". I went ahead and attached some diagrams of the # KPG5-R30IP below. I don't have the full height down to the bottom of the pin but I can get it if that is what you're looking for. Just let me know in the comments below.

Helo Robin. Thanks for this info! It is very helpful. If you could also get me the length down to the bottom of the pin that would be great! Thanks.

@Jackson I'm glad I went out there since that original measurement was off or on an older version of this. It is 22-1/2" down to the plate and another 4" down from there so 26-1/2" overall.
