RETRUE Trailer Hitch Receiver Pin Lock 2 in - Secure 5/8 in Pin (4

In this review the RETRUE Trailer Hitch Receiver Pin Lock is evaluated as a straightforward, budget-minded security option for owners of larger towing setups. It is aimed at drivers who need a robust locking pin for a 2 in receiver and Class III or IV hitches, with the single biggest reason to buy being its heavy-duty construction and long effective length that fits many bike racks and tow accessories. The pack of four pins and the included rubber rings make it useful for people who want multiple locks or spares for several trailers or racks.

Key Features

• 5/8 in Diameter Pin: Offers a standard, heavy gauge shaft that fits most 2 in receivers and Class III/IV hitches for secure towing connections.
• Extra Long Effective Length: The 2 3/4 in effective length is designed to clear larger hitch openings and thicker accessories such as bike racks or tray mounts.
• Zinc Alloy Lock Cylinder: The tubular zinc alloy cylinder provides durable resistance to impact and tampering for better anti-theft protection.
• All-Weather Key Slot Cap: A rubber key slot cap keeps the keyway clean and protected from rain and dirt to preserve lock function over time.
• Solid Steel Construction: The pin is covered with solid steel and black electrophoretic paint to resist corrosion and claim a high load capacity for heavy towing setups.
• Four-Pack Convenience: Includes four locks and noise-reducing rubber rings so users can secure multiple hitches or keep spare units handy.

Who It's For

This lock is best for truck and towing vehicle owners who use a 2 in hitch receiver on Class III or IV setups, and for people who mount bike racks, tray mounts, or ball mounts that require a longer-than-standard pin. The four-pack format suits fleet owners, households with multiple vehicles, or anyone who wants spares for trailer and rack combinations.

Those who should look elsewhere include buyers who need a longer pin than 2 3/4 in effective length for specially recessed receivers, or shoppers who prefer keyed-alike systems from their hitch and other locks; some customers reported mixed fit and length concerns on a minority of 2 in receivers.

Pros & Cons

• Sturdy 5/8 in shaft and solid steel construction provide dependable physical strength for towing use.

• Four-pack and included rubber rings deliver good value and reduce rattling on the hitch.

Cons

• Some buyers found the effective length too short for certain 2 in receivers or recessed mounting situations, so measurement before purchase is important.
