CZC AUTO Hitch Locking Pin for 2" & 2.5" Receivers — 5/8" Hardened Pin, Keyed-Alike, 3.5" Length

This heavy-duty dogbone-style trailer hitch lock from CZC AUTO is engineered to keep trailer-mounted gear — bike racks, cargo trays, hitch balls and more — secured to 2" and 2.5" receiver tubes. The lock uses a 5/8" hardened pin with a 3-1/2" effective length and a rotating head for easier alignment, while a keyed-alike configuration lets multiple locks be opened with the same key set. Built from carbon steel with an electrophoretic black finish and protected key slot, it’s designed for regular towing use and all-weather exposure.

How does this hitch lock improve theft deterrence and trailer security?

The solid 5/8" hardened pin and locked dogbone head create a tamper-resistant connection between the hitch accessory and receiver, making quick thefts difficult. The lock head’s 360° rotation and snug fit reduce leverage points, while the keyed cylinder and rubber dust cap protect the mechanism.

• 5/8" diameter hardened pin resists bending and cutting attempts
• 3-1/2" effective length fits Class III/IV hitch tubes
• Electrophoretic black finish reduces corrosion and glare
• Rubber key slot cap prevents moisture and debris entry

Will this fit my 2" or 2.5" receiver and common hitch accessories?

Yes — the CZC AUTO pin is sized specifically for 2" and 2.5" (2-1/2") receiver tubes and matches the standard spacing of most hitch-mounted accessories. The design accommodates items such as ball mounts, bike racks and cargo carriers used with Class III and IV setups.

• 3-1/2" effective pin length for secure insertion into receiver tube
• Dogbone-style head clears common hitch-mounted accessories
• Compatible with hitch racks, cargo trays, hitch balls and tow attachments
• Straightforward fit for most 2" and 2-1/2" factory and aftermarket receivers

How easy is it to use and maintain the keyed-alike set?

Operation is simple: insert the pin, rotate the head into place and turn the key to lock. Each set ships keyed alike — up to four locks can be operated by the same keys — and comes with spare keys. Routine rinsing and occasional lubricant keep the zinc alloy core working smoothly.

• Includes two keys per lock, eight keys total for four-lock sets
• Keyed-alike design eliminates need for multiple keys
• Quick-lock action: pull the head after locking to confirm engagement
• All-weather rubber cap shields the tubular keyhole from corrosion

What materials and protections ensure long-term durability?

The CZC AUTO hitch lock uses carbon steel finished with electrophoretic coating for scratch and rust resistance. The lock core is zinc alloy, and the keyed entry is topped with a rubber dust cap to reduce moisture and grime ingress, extending service life in wet or muddy conditions.

• Carbon steel construction for strength and rigidity
• Electrophoretic black coating for corrosion resistance
• Zinc alloy lock core balanced for durability and smooth operation
• Protective rubber key slot cap to prevent water and dirt buildup

Who is this for: Drivers who haul trailers, bike racks, cargo carriers or other receiver-mounted accessories and want a rugged, user-friendly way to deter theft and secure gear. The lock is ideal for owners of Class III/IV towing setups who need a dependable, keyed-alike option that stands up to regular outdoor use and simplifies access across multiple locks.
