BulletProof Hitches 5/8" Trailer Hitch Locking Pins 2-Pack

The BulletProof Hitches 5/8" Trailer Hitch Locking Pins are a two-pack of stainless steel receiver pins designed to secure any 2", 2.5", or 3" trailer hitch receiver, rated to the full maximum capacity of the hitch from 14,000 to 36,000 lb. Both pins in the pack are keyed alike, so one set of keys operates both locks.

Rated to the Hitch's Full Capacity

Most hitch pins are retention hardware only. These pins are rated to match the hitch's own maximum capacity, from 14,000 to 36,000 lb depending on the receiver. That rating means the pin is not the weak point in the connection, which matters when towing heavy trailers or leaving a loaded hitch accessory unattended. The thick, lockable barrel adds a physical deterrent against removal without the key.

Anti-Rattle Fit Across Three Receiver Sizes

Each pin is 5/8" in diameter with 4" of usable length and ships with both a 2" and a 2.5" anti-rattle stabilization spacer. The spacers eliminate side-to-side movement in the receiver channel without requiring separate hardware. The universal design fits 2", 2.5", and 3" hitch receivers, and the pins can also secure a dual ball mount or other BulletProof hitch accessories in the receiver.

Stainless Steel with a Sealed Rubber Cap

The pins are stainless steel throughout, chosen for corrosion and rust resistance in outdoor and road-spray conditions. A weather-resistant rubber cap with a tight, thick-walled fit seals the exposed end of the lock barrel, keeping debris and moisture out of the locking mechanism during storage or extended towing use.

Who This Is For and Isn't

These pins suit any driver who uses a 2", 2.5", or 3" hitch receiver and wants a locking pin rated to the hitch's full capacity, whether securing a ball mount, a hitch-mounted carrier, or a dual ball accessory, and whether the concern is theft deterrence or a solid, rattle-free hold during towing.

These pins do not fit receivers smaller than 2" or larger than 3". They are not a coupler lock and do not secure the trailer-to-ball connection; they secure the accessory or ball mount inside the receiver tube only.

Common Questions

Will these pins fit my factory hitch receiver?

The BulletProof Hitches 5/8" locking pins fit any 2", 2.5", or 3" hitch receiver regardless of vehicle make or model. If the receiver accepts a standard 5/8" pin, these are compatible. They do not fit receivers smaller than 2" or larger than 3".

Do both pins in the 2-pack use the same key?

Yes. The two pins in this 2-pack are keyed alike, meaning a single set of keys operates both locks. Each pin ships with two matching keys, giving the 2-pack four keys total, all cut to the same code.

What is included with each pin?

Each BulletProof Hitches locking pin ships with a 2" anti-rattle stabilization spacer, a 2.5" anti-rattle stabilization spacer, two matching keys, and a weather-resistant rubber end cap. No additional hardware is required for installation in a standard receiver tube.

How does the anti-rattle spacer work?

The 2" and 2.5" stabilization spacers slide onto the pin before it is inserted into the receiver, filling the gap between the pin and the receiver walls. This eliminates the side-to-side movement that causes the clunking noise common with loose-fitting hitch pins, without requiring tools or additional hardware.
