Build your wheels exactly the way you want with Boom Racing's all-new ProBuild Wheels [Patent Pending].
The idea behind PROBUILD was to find a way to make a fully customizable and adjustable wheel with multiple setup options. Today, that sounds really smart, but back when we started most people thought we were crazy. That’s alright, everything has its time!
Quality off-road wheels are not always affordable. Most of us save our money to get a nice set. Deciding on the right set of wheels can end up being a scary and expensive learning lesson. Our proprietary customizable design completely removes any fear of getting another set of wheels that are “almost right”. We took into consideration all of the desirable wheel features - style, color, offset, material, total width, weight, hub size, hardware styling, etc., and provide the options to adjust the wheel to the way you like.
What makes PROBUILD probuild?- High changeability, unlimited possibilities
- Built-in offset options
- Revolutionary and cutting edge designs
- Engineered to the exact specifications of world-class drivers
With unlimited combinations of colors, faceplates, multiple offset options, etc, ProBuild wheels is a game-changing design for how we build and match custom rigs. No longer are we stuck with a full set of wheels that remain the same for too long.

7mm Nut Driver Adapter #BRT10045
Have you ever had issues with nut drivers being too large? Since there are no industry standards for nut driver head sizes, a lot of wheels are designed with a bigger "hole in the middle" to fit the most common nut drivers out there.
When drawing up new designs we always aim for the best possible looking wheels. Minimizing the center area means there is more room to play with on the face design. This new 7mm Nut Driver Adapter has a smaller hex head diameter, which guarantees any hex nut driver to work with most likely any wheels out there, especially newer 1.9s and 1.55s.
We believe everyone in RC should have this in their toolboxes, and so for every pair of the upcoming ProBuild wheels, we are including one 7mm Nut Driver Adapter each, which means you will get two of them for every set of ProBuild wheels.
2.5mm Scale Socket Driver Tool
The 2.5mm Scale Socket Driver Tool works with Boom Racing ProBuild Mag Seat Scale Lug Nut screws. Each pack of ProBuild wheels includes one 2.5mm Scale Socket Driver Tool, which means you will get two of each when you get two pairs of wheels.
An awesome handy tool to have in any toolbox. You can also hang this on a keyring for convenience.

⭐️⭐️⭐️⭐️⭐️
Color: Grey
Very satisfied with this room divider. The construction is sturdy and stable, easy to assemble, and stands firmly without extra support. It separates the space well and provides good privacy. The grey color looks stylish and neat, blending perfectly with the interior. The quality fully met my expectations.

Not so good as expected.
Color: Grey
Pretty poor quality partition. It should hold up to normal indoor ware as long as to don’t touch it. If it is used in a garage (as I did) it will collapse.when subjected to any kind of a breeze at all. I had to reinforce the partition with cross-wires for added support and it was still not enough.

Functional but not attractive
Color: Black, Color: Black
I purchased this to hide my cats liter boxes as he refuses to use them unless they are on the finished side of our basement which is also my kids play room. This functions as I’d expect. It isn’t great to look at but better than cat boxes. Overall it might make a good backdrop if needed. My only complaint is the hex/allen wrench doesn’t fit in the screws provided. If you don’t have an alternative tool that’s a smaller hex it will be annoying to put together.

Does the job!
Color: Grey, Color: Grey
This is a great screen to separate a space The base could be a bit sturdier, but for the price, it does the job! I recommend having a mallet for ease of assembly.

Good
Color: Grey, Color: Grey
The room divider seems to be a great quality. It is easy to assemble and set up. The stability of it is good. It doesn’t knock over easily. I use it when I have company over to divide a room to give them privacy. I might also use it on my patio to keep the wind And cold air while I sit and enjoy outside.
