Video Transcript for Review of the UWS Replacement J-Bolts for Crossover Toolboxes
Hello, neighbors. Steven here with etrailer.com. Today we're looking at the UWS Replacement J-Bolts for a crossover style toolbox. So folks, again, this will replace the mount hardware or missing hardware if you bought maybe a used box or something like that. But specifically for attaching a UWS crossover style toolbox to your truck bed rails. You get the two J-bolts, the two washers and the two nuts.
These washers are kinda thick, about an eight-inch thick. And as far as the J-bolts, went ahead and do some measurements here. Overall length was right at about 3 inches long, while the thread length was about 1 7/8ths long. And I was getting about a quarter-inch thick on the bolts themselves. Well, folks, that will wrap it up for our look at this simple UWS Replacement J-Bolt kit.
Again, for crossover toolboxes. I'm Steven. Thanks for your time. Thanks for watching and stay safe.

These J bolts really work.
I purchased them and installed my toolbox in the bed of my truck, it is full of over 1Ton of chains, towing hookups, hitches, etc.
Feb 2023 I was hit headon by a woman doing over 60mph, my truck was totaled!
The next morning looking at my truck I noticed that the toolbox didn't move at all. I opened it up and checked the bolts, both sides were fine.
I have a new truck now and the toolbox and the same J bolts are in my new truck.
Great product.

I hate writing reviews because my writing sucks and I have little to say. Anyhow, this should work better at holding the tool box to my car than the last pair that I bought.

The design of these hooks is ideal for securing my truck bed decked box. However the length is too short. These will not work in a 2017 Ford Superduty Shortbed.
