Will the Reese M5 5th Wheel Hitch Work With A King Pin On A Race Car Trailer

Question:

my trailer is a race car trailer and not a rv, my kingpin, like a semi trailer, is 1 1/2inch high for the groove section. I see the locking jaw is a thick piece, will it fit in my kingpin? dont know about rv kingpins, if locking jaw does fit, could mine be a loose fit for the locking jaw thickness?

Helpful Expert Reply:

The dimensions of a king pin are an industry standard between both RV's and Semi's. Therefore, if you wanted you could actually tow an RV with a Semi. The standard dimensions for the king pin are 2" diameter and the groove is indeed around 1-1/2" tall so I do not see any irregularities with your trailer and you can use the Reese M5 Series 5th Wheel Trailer Hitch part # RP30921 no problem. The thickness of the jaw will not be an issue as it does not exceed 1".
