The TowWorks 79831 Keyed Unique Trailer Hitch Lock is *exactly* what I needed for my 2024 Tacoma! The extra-long 4-1/2" span is the perfect size to fit the oddly sized receiver hitch with no hassle. It locks securely and gives me complete peace of mind when towing or leaving my hitch attached.The double safety design is a great feature, and the overall build quality feels solid and reliable. It’s easy to use, and the keyed lock adds an extra layer of protection. If you’re looking for a hitch lock that fits larger receivers perfectly, this one is a must-have. Highly recommend!

This locking hitch pin is compatible with the latest generation Tacoma, making it an excellent choice for those looking to secure their hitch. After trying out several locking hitch pins that claimed to fit this newer style hitch, I finally found this one, which offers the perfect length for a secure lock. Its design ensures that it provides the necessary clearance to lock the hitch pin effectively. As for its long-term durability, only time will tell how well it withstands the elements and regular use. I’m hopeful it will hold up well.

My new Tacoma Trailhunter Hitch housing is too big for my 1Up Swing Out. None of my pins would work. Although it’a not threaded, it is the First extra long hitch pin I have found and it worked out great.

Purchased this 4-1/2†locking pin to replace a clip pin that was included in a 2†JEXTRA tow & stow Tri-Ball Hitch kit. This 4-1/2†pin serves to deter theft of the JEXTRA Tri-Ball adjustable attachment to prevent someone just pulling clip pins and stealing Tri-Ball. Hope this helps others!

I needed a longer hitch lock to fit on my 2024 Tacoma and this works perfectly. Happy with the quality and the overall design. Just what I needed and a decent price as well.

Unfortunately living in the sign of the times we have to lock and chain and bolt our possessions to maintain safe keeping these days anymore
