Blue Ox tow bar lock kit BX88101 — Orange 2× 1/2" + 1× 5/8" keyed locks, high-visibility theft deterrent

Whether you tow a car, SUV, or light truck, the Blue Ox BX88101 lock kit gives a simple mechanical way to reduce accidental unhitching and add theft-deterrence to your tow setup. Built to integrate with common tow bars, the kit uses two smaller 1/2" locks for the primary connection points and a robust 5/8" receiver lock for accessory protection. The bright orange finish improves visibility and makes it easy to confirm locks are in place before you start towing.

How does the BX88101 prevent accidental unhitching?

The kit physically secures the tow bar to both the vehicle’s base plate and the receiver, locking the moving parts and keeping pins from backing out during transit. These positive mechanical locks stop vibrations and road forces from loosening connections.

• Two 1/2" locks anchor the tow bar hitch points to the base plate.
• One 5/8" receiver lock secures the receiver-mounted accessory or hitch pin.
• Solid metal construction resists deformation under load and vibration.

Will this kit fit my existing tow bar and receiver?

The BX88101 is designed around common industry pin sizes—1/2" and 5/8"—so it fits most standard tow bars and receiver setups that use corresponding diameter pins. Verify your tow bar and receiver use these pin diameters before buying to ensure compatibility.

• Two 1/2" locks for typical tow bar connection points.
• One 5/8" lock for standard receiver-mounted accessories or larger pins.
• Check current pin diameters and installation clearance before installation.

How durable and visible are these locks on the road?

Blue Ox constructs the locks from sturdy metal to withstand road stresses and frequent use. The orange finish increases visibility so you can perform quick pre-trip inspections and spot an unsecured connection at a glance.

• Durable metal components resist wear and deformation.
• Bright orange coating aids quick visual checks and reduces missed locks.
• Designed for repeated installation and removal during regular towing cycles.

What do I get in the kit and how easy is it to use?

The BX88101 kit ships with two 1/2" locks, one 5/8" lock, and the keys needed to operate them. Installation is simple: insert each lock through the corresponding hitch pin bore and turn the key—no special tools required.

• Two keyed 1/2" locks for tow bar-to-base plate security.
• One keyed 5/8" receiver lock for accessory or hitch pin security.
• Keyed operation for straightforward install and removal.

Who is this for? The Blue Ox BX88101 is aimed at recreational vehicle owners, RV renters, and drivers who flat-tow or tow frequently and want an affordable, easy-to-use way to secure their tow bar assembly.
