2-Inch Trailer Hitch Pin
Choosing the right 2-inch trailer hitch pin matters because this small part is the single mechanical link that keeps a hitch-mounted accessory secured in a receiver tube. If the pin diameter, span, or retaining method is wrong, the connection can loosen, rattle, or separate under load. The decision should account for receiver condition, hitch accessory weight, tongue weight, towing configuration, and how often the pin is removed. This article explains what to check before ordering and how to match a pin to the way the vehicle is used.
The direct answer
A 2-inch trailer hitch pin is typically a straight drawbar pin with a nominal diameter of 5/8 inch, shaped to pass through both walls of a 2-inch receiver opening. The important confirmation is not just the 2-inch receiver size but also the load rating and retaining design. A standard pin and clip is sufficient for many utility uses, while a locking pin adds basic theft deterrence. For load-distributing or heavy accessory setups, the pin must be strong enough for the vehicle's gross vehicle weight rating and hitch rating rather than selected by receiver size alone.
When comparing options, check that the pin is long enough to pass fully through the outside width of the receiver and that the clip or lock seats on the opposite side. Worn receiver holes can make a correct-diameter pin fit loosely, increasing movement. For heavier loads, consider a stainless or hardened pin whose corrosion resistance and shear strength align with the expected tongue weight and gross trailer weight. In every case, the pin works only as part of a full assembly that also includes the correct hitch ball mount, receiver rating, and vehicle payload capacity.
