When it comes to towing, security and peace of mind are just as important as strength and reliability. The Curt 5/8" Hitch Lock is designed to give you both. Built with a heavy-duty deadbolt mechanism, this hitch lock keeps your ball mount or hitch-mounted accessory securely attached to your receiver—protecting your trailer, gear, and vehicle from theft. Unlike a standard hitch pin, this lock doesn’t just hold everything in place; it actively secures your setup against tampering or removal.
Crafted with a durable chrome-plated finish, the lock resists rust, corrosion, and daily wear, making it a smart long-term investment for anyone who tows regularly. It’s engineered with a universal 5/8" pin diameter that fits 2", 2-1/2", and even 3" receiver tubes, making it one of the most versatile towing locks available. The quarter-turn key operation is simple and intuitive, while the watertight dust cap protects the internal mechanism from dirt, water, and road grime—ensuring reliable performance season after season.
