2024 Tacoma hitch lock pin size

[Liquidassets]

Just an FYI, I have a 2024 Tacoma off road with the stock hitch. The pin diameter is 5/8". It seems like the hitch pin should be 3.5" but my Tacoma hitch requires a 4.0" pin.

First, I tried the standard rhinousa hitch lock which was way too short. I then looked up reviews which that stated the 2022+ tundras were compatible with the larger "2.5 inch rhinousa hitch lock" which in reality has 3.5" of usable length. The 2.5 inches refers to the receiver size. This was a barely too short for the lock to engage and had to be returned.

In the end, I needed a 5/8" diameter by 4.0" effective usable length pin. It is slightly longer than it needs to be, but fits after trying 2 prior.

I bought this cheap one which doesn't include a safety pin. I'd be interested to hear if someone can fit a 3.75 inch hitch lock.

I remember reading this months ago not really thinking much of it because I didn't understand the issue. When I went to use my locking hitch pin for the first time today I realized the problem... Too short now I get why the truck includes one from factory.

Thanks for doing the research for us!

Hoping Factor55 will make one. Does anyone know why Toyota added an extra box around the hitch. I’ve got a hitch skid to add but I don’t want $250 hanging on the hitch unsecured.

Can just barely fit 3-3/4" long.
Any pin sold as 5/8" x 4" will work.

I bought this one (they also make a black appearance version if you desired for about a dollar or two more).

Ran into the same issue with the pin for my Yakima bike rack. Because of the wider Tacoma hitch the bolt wasn't long enough to get the lock in the end. Couldn't find a longer one anywhere. Luckily a friend whose is a millwright made on for me. I'm also wondering why the wider hitch?

I found a locking one at Tractor supply. They had multiple brands in the long length on the shelf.
