Blue Ox BX88101 tow bar lock kit — two 1/2" locks + one 5/8" lock, high-visibility orange, heavy-duty security

Blue Ox BX88101 is a three-lock kit—two 1/2" locks and one 5/8" lock—designed to secure your tow bar to both base plate and vehicle receiver for dependable on-road locking.

Protecting your tow setup is as important as choosing the right tow bar. The Blue Ox BX88101 3-Lock Kit gives you the specific lock sizes commonly required to keep the tow bar attached to the base plate and the receiver, plus an extra receiver lock for other hitch-mounted accessories. Built with durable materials and finished in high-visibility orange, this kit aims to make installation straightforward while reducing the chance of accidental unhitching.

How does this kit keep a tow bar secured during transit?

Each lock engages existing hitch and base-plate components to prevent the tow bar from separating while driving. The 1/2" locks fit the tow bar attachment points, and the 5/8" lock secures the receiver or auxiliary accessories, creating multiple locking points for redundancy.

• Two 1/2" locks lock the tow bar to the base plate connection points.
• One 5/8" lock secures the receiver or other receiver-mounted gear.
• All locks install with simple pin-and-sleeve action—no special tools required for routine use.
• High-visibility orange finish helps you confirm locks are engaged before driving.

What materials and construction details make these locks dependable?

The locks are manufactured to resist wear and everyday road stresses with a heavy-duty build. The internal locking mechanism and thick shank diameters were chosen to provide mechanical strength and lasting service in towing conditions.

• Robust metal bodies engineered for strength and durability.
• Corrosion-resistant finish to withstand outdoor exposure.
• Precision locking components to reduce play and keep a snug fit.
• Color-coded orange finish for easy visual confirmation of lock presence.

Which vehicles and accessories are compatible with the BX88101 lock kit?

This kit is tailored for common tow bar and receiver systems that use 1/2" and 5/8" locking pins. It works across many base plate-to-tow bar interfaces and receiver-mounted accessories that accept a 5/8" lock, making it versatile for typical flat-tow or towing rigs.

Removal is equally straightforward, allowing fast hookup and takedown while still providing a secure hold when locked.
