Koch Industries, 5/8 by 6-1/4-Inch, Color Koch 4012323 Swivel Handle Forged Hitch Pin

Koch 4012313 Swivel Handle Forged Hitch Pin, 5/8 by 4-1/4-Inch: this is the pin that fits well my 2012 Toyota Sequoia, and presumably a late model Toyota Tundra. Our hitches are a little wider than most, so the 4.25 inches is good; our hitches are with a 5/8 inch hole (rather than a 1/2 inch hole). This information I could find on no website, including the Koch site. Measuring on the truck still leaves some ambiguity. Hope this helps a fellow Toyota truck owner.The loopy metal thing, although nice to grab and pull out the pin, is in the way, especially for my truck. There is no need that it be as large and in the way as it is. It hits the electronic coupling for trailer lights that is astride the hitch. If the loop was half the size, it would be no problem with any truck, it would save the manufacturer on manufacturing metal, and it would still be easy enough to yank out. That said, this can be used on a Toyota truck, it just takes a bit of finagling to get the ring just right to pull it out (I'm considering cutting the ring off altogether).

Worked and fit perfect. Needed a long hitch pin for the trailer and this did the trick. Only missed one star as the locking clip was really tiny for how large the rest of the hitch pin was. Not a huge deal, but would do better with a bit larger and thicker locking clip.

Too big for my needs. The length was good but the diameter just a bit too large. Only 4 stars as I have no way of knowing if it will hold up under stress.

I have a trailer with a tank and a pump I pull behind my yard tractor for spraying weeds. Previous to buying this pin, I used a 4 inch bolt to attach the trailer to the tractor. Problem was, I did not put a nut on the bottom of the bolt and the trailer bounced off. Of course, I did not realize it until I got a tug on the hose. By then, the wires had pulled loose from the pump. I did not put a not on the bolt because that was too much hassle. With this pin, I just slip in the cotter pin - or slip it out to remove the pin. Wish I'd used this from the start. The strength is fine for a small trailer pulled behind a yard tractor.

Got the job done for what I needed. Not all the same size, however. Some of them are a hair too thick despite being labeled the same... Took some adjustments.

This hitch pin was perfect for hitching up the little 10 cubic foot dumper-trailer I bought for my small yard tractor. Most hitch pins you can find in stores are 1/2 inch diameter, the 3/8 inch ones are hard to find, and the few that I have found are either not long enough, or are junk...one I had prior to this had a U-shaped clasp that went out from the bottom, up the side, and back on to the top, and the problem was whenever you made even a slightly sharp turn it bent the clasp. This one is of very nice quality, is a good length, and good design. Highly recommended.

Hitch pin looks fine, but box did not include the hair pin to attach it with.

Nice anodized pin, only qualm with it is they put their sticker on the shaft ere you don't want anything to catch when your inserting it into what you bought it for
