CZC AUTO Trailer Hitch Lock Pin 5/8" x 4" Extra-Long Two-Pack — Keyed Alike, Heavy-Duty Steel with Tubular Lock

Heavy-duty 5/8" CZC AUTO trailer hitch lock pin with a 4" extra-long shaft—sold as a keyed-alike two-pack to secure Class III and IV receivers.

Protecting your hitch-mounted gear starts with the right pin: this CZC AUTO set pairs a robust steel shaft with an upgraded tubular lock core and watertight dust cap to resist tampering, moisture, and grime. Designed for larger towing setups like trucks, trailers, and multi-fit bike racks, the 4-inch effective length gives extra reach for thicker hitch receivers and accessories. Each lock ships keyed alike (two keys per set) so both pins open with the same key for convenient operation.

How does this lock fit different hitches and accessories?

The 5/8-inch diameter pin is a common size for heavier-duty Class III and IV receivers; the 4" extra-long shaft accommodates thicker receivers, hitch-mounted accessories, and layered mounting plates. Still, measure your receiver and accessory stack before buying to confirm fit.

• Designed for Class III and IV receivers and larger towing setups
• 4" effective length for thick plates, bike racks, tray mounts, and ball mounts
• Check receiver inner width and accessory bracket thickness before purchase

What security features does the CZC AUTO hitch pin offer?

The pin body is solid steel finished with a corrosion-resistant coating, and the tubular lock core uses upgraded anti-theft design elements to improve pick resistance. A watertight dust cap shields the keyway from water and debris, extending service life in wet or salty environments.

• Solid steel pin with black protective coating to resist rust
• Upgraded zinc-alloy tubular lock core for improved anti-theft performance
• Watertight dust cap prevents keyway contamination

How easy is it to operate and maintain?

Operation is straightforward: insert the pin, push the locking head into place, and use the supplied key to lock or unlock. Each set includes two identical keys so both pins in the pack open with the same key, simplifying use across multiple attachments.

• Two keys included per set; both pins keyed alike for convenience
• Simple push-to-lock action—pull on the head after locking to confirm engagement
• Regular cleaning and occasional lubricant prolong lock life
