Locking Hitch Pin For 2-2.5 Inch Hitch Receivers Factor 55

The Factor 55 Locking Hitch Pin is built for 2-inch and 2.5-inch hitch receivers and does exactly what a standard hitch pin can't — it locks your ball mount or accessory in place so it isn't walking off without your keys. This is the security upgrade a basic cotter pin simply doesn't offer.

The pin is machined from 303+ high-strength stainless steel, comes in at 5/8-inch diameter with a 3-1/8-inch span, and is rated to 50,000+ lb. shear strength. That's not a marketing number — it's an engineered, tested figure from a pin made entirely in the USA. Internal components are protected by o-rings, and the keyway stays clean thanks to an integral weather-resistant tethered dust cap.

We like the grooved low-profile head — it gives you a real grip when you're pulling the pin in the field. The key-rotation lock mechanism is solid, though Factor 55 is upfront that you'll need sufficient hand clearance around the receiver to rotate the key. Two keys are included out of the box.

For anyone running a ball mount, bike rack, cargo carrier, or recovery gear off a receiver hitch, this is the pin we'd put on it. Made in the USA, rated for serious shear loads, and built to stay weathertight.
