Trailer Hitch Locks 5/8 in Pin for Class III IV 2 in Receivers - 4

In this review, the Trailer Hitch Locks 4 pack is assessed for everyday towing use and simple theft deterrence. The bottom line: this set is for owners of Class III and IV 2 in hitch receivers who want a robust, easy-to-use locking pin that also stops rattle. The most compelling reason to buy is the combination of a push-to-lock mechanism and solid steel construction rated to handle heavy loads, making it a practical upgrade for truck, trailer, boat or camper owners who value convenience and quieter towing.

Key Features

• Universal fit: The 5/8 in diameter and 2-3/4 in length make these pins compatible with most Class III and IV 2 in hitch receivers, reducing fit guesswork.
• Push-to-lock design: The lock engages by pushing the pin through the receiver and requires only a small turn of the key to release, simplifying day-to-day use.
• High load capacity: Solid steel construction with black electrophoretic paint supports heavy towing and resists wear over time for confident hauling.
• Anti-rattle O-rings: Sixteen included rubber O-rings let you tune the fit to minimize rattling and noise while towing.
• Complete kit: The 4 pack ships with multiple keys and upgrade button heads so you get spare keys and parts for several vehicles or trailers.

Who It's For

This 4 pack is aimed at vehicle owners who regularly tow or carry hitch-mounted accessories and want a straightforward, durable locking solution. It is especially useful for truck, trailer or boat owners who need a universal pin that fits most Class III and IV 2 in receivers and who appreciate the push-to-lock convenience.
