Trailer Hitch Locks, 5/8’’ Dia Pin Fits Class III IV 2"

META Hardware trailer hitch locks are heavy-duty 5/8" diameter locking pins designed to secure 2" Class III and IV receivers, supplied as a 2-pack with keys, O-rings, and upgraded lock heads.

These trailer hitch locks replace a standard hitch pin with a keyed, anti-theft locking system built from solid steel and zinc-alloy components. They fit most 2" receiver applications, offer push-to-lock convenience, include vibration-reducing rubber O-rings, and are rated to withstand substantial towing loads. The set includes two 5/8" pins, upgraded button heads, four keys per lock, and extra O-rings so you can outfit multiple trailers, accessories, or vehicles.

How do these locks fit my 2" Class III or IV receiver?

The locks are sized with a 5/8" diameter pin and a 2-3/4" overall length to match common 2" receiver hitch holes. They slide into the receiver and secure with an internal locking mechanism so you keep the hitch accessory firmly attached.

• 5/8" (0.625") pin diameter for standard receiver holes
• 2-3/4" pin length ideal for most Class III/IV setups
• Works with ball mounts, cargo carriers, bike racks, and tow accessories
• Supplied in a 2-pack for dual-vehicle or spare use

What makes the push-to-lock design convenient and secure?

The push-to-lock feature allows quick installation: push the pin into the receiver and it engages automatically without repeatedly turning the key. To remove, insert the key and turn slightly—the locking pin will release and pop out for fast removal.

• Push-to-lock for one-handed, tool-free use
• Keyed tubular zinc-alloy core for tamper resistance
• Quick-release action with a light key turn
• Comes with four keys per lock so spares are available

How durable and anti-theft are these hitch pins?

The frame is forged from solid steel with a protective black electrophoretic finish to resist corrosion and wear. The internal lock uses a robust zinc-alloy tubular core and the whole assembly is engineered to carry heavy loads while resisting forced removal attempts.

• Solid steel construction with corrosion-resistant coating
• Zinc-alloy tubular locking core for increased security
• Load capacity engineered to handle heavy towing demands
• Upgrade button lock head for improved tamper resistance

Will these locks reduce rattle and vibration during towing?

Yes — the kit includes eight rubber O-rings designed to cushion the connection between the pin and hitch, reducing play and annoying rattling noises when driving. Properly installed O-rings create a tighter fit and quieter tow experience.

• Eight rubber O-rings included for noise reduction
• O-rings fit around the pin to minimize movement and vibration
• Extra O-rings provided for later replacement or multiple setups
• Helps protect finish on hitch and accessory shanks

Who is this product for? Installers, frequent tow drivers, and anyone who wants a stronger, quieter, keyed hitch pin instead of a standard clip-style pin will benefit from META Hardware's trailer hitch locks. This 2-pack is ideal for businesses with multiple trailers, families with more than one tow vehicle, and recreational users who need reliable anti-theft protection and reduced hitch noise without sacrificing quick operation.
