Tyger Auto Solid Trailer Hitch Lock Pin — 5/8-inch for 2-inch Receiver, Weatherproof Anti-Theft

Tyger Auto's TG-HL3U001B is a weather-resistant, solid barbell-style trailer hitch lock pin that secures 5/8-inch pin holes on 2-inch hitch receivers for heavy-duty towing.

When you tow, the connection between your trailer and vehicle is the most vulnerable point for theft or accidental disconnects. This lock pin replaces a standard hitch pin with a hardened locking shaft and a sealed cap to shield the mechanism from water and dirt. Built to fit Class III, IV, and V setups and rated for heavy loads, it offers a simple, robust way to add security without altering your hitch.

How does this hitch lock protect my trailer during everyday use?

The lock pin slides through the hitch receiver and trailer tongue, then secures with a keyed cylinder so the trailer cannot be detached without the matching key. Its solid construction resists bending and tampering compared with thin clip-style pins. A protective cap keeps debris and moisture out of the lock for dependable performance.

• Solid barbell-style steel shaft minimizes flex and breakage risk
• Sealed sliding cap prevents corrosion and jammed locks
• Keyed cylinder requires the included key to remove

Will this fit my vehicle and trailer setup?

This model is designed specifically for 5/8-inch pin holes on 2-inch (Class III/IV/V) hitch receivers. It suits most full-size trucks, SUVs, and trailers that use that common pin diameter. Be aware it is not compatible with certain Tyger hitch-mounted bike racks referenced by specific SKUs.

How durable and weatherproof is the TG-HL3U001B?

The lock was engineered for heavy towing conditions with a high load rating and protective features to extend service life. The solid locking bar and weather cap reduce the chance of lock failure from rust or grime. This combination makes it suitable for regular towing and storage in exposed environments.

• 19,000 lb load rating for high-capacity towing confidence
• Black finish resists surface damage and blends with most receivers
• Sliding cap keeps water and dirt away from the locking cylinder

What’s included and how easy is it to use?

It's a good fit for frequent haulers, fleet vehicles, and anyone who parks or stores trailers in public or exposed areas and prefers a durable, low-maintenance locking pin over basic clips or cotter pins.
