2 in & 2.5 in Receiver Lock Pin - Heavy Duty Hitch Lock for Trucks

In this review the InfiniteRule 2 in & 2.5 in receiver lock is recommended for towing owners who need a rugged, application-specific anti-theft solution. The single biggest reason to buy is the lock's heavy duty, machined construction and threaded head-over-pin design that gives clear security advantages over simple cotter-pin style pins. Buyers should verify span and diameter before ordering, since this product is explicitly made to fit particular class III, IV, and V receivers and is not a universal fit.

Key Features

• Application specific fit: Designed for 2 in and 2.5 in receiver shanks so it fits Class III, IV, and V hitches without excess play when the correct span is selected.
• Robust anti-theft design: The patented threaded lock system and head-over-pin layout provide a more secure locking method than standard hitch pins, reducing casual theft risk.
• Durable construction: Made from premium materials that resist corrosion and include a weatherproof rubber cap and O-ring to protect the lock from rain, grime, and road debris.
• High load rating: Uses a 5/8 in pin with a 3-1/8 in span rated to 21K lb for heavy towing applications when matched to compatible hitches.
• Made in the USA: Manufactured, shipped, and serviced domestically, which supports consistent quality control and local support.

Who It's For

The 2 in & 2.5 in receiver lock is ideal for truck and trailer owners using Class III, IV, or V receivers who want a rugged, American-made anti-theft hitch pin with a threaded lock mechanism. It suits fleet owners, landscapers, and frequent towers who attach expensive accessories or tow trailers and need an upgrade from simple locking pins.

Customers who are unsure about fit or who use nonstandard hitch shanks should measure their receiver and pin span carefully before purchasing; those with Gen-Y Mega Duty 10K or 16K systems should choose the specified alternate part number. If you need a universal, one-size-fits-all pin, this application-specific product may not be the best choice.

Pros & Cons

Pros

• Solid build quality and a tight fit when matched to the correct receiver provide strong lock security.
• Weatherproof protections like the rubber cap and O-ring extend durability in wet or dirty conditions.
• Clear, heavy load rating and heavy duty materials make it appropriate for serious towing tasks.
• Domestic manufacturing ensures consistent production and customer support.

Cons

• The screw-on mechanism receives mixed feedback; some users find it slower to operate than quick-release pins.
• Must confirm exact span and diameter before purchase, which adds a step to buying compared with universal pins.
