The GripBox is a wheel-mounted button box designed to bolt directly to any 70mm PCD steering wheel, giving you a huge amount of functionality without the huge price tag that usually comes with it. Built around a custom PCB, it packs 24 inputs, three rotary encoders with push-click functionality, a five-way hat switch, LED backlit buttons, and a full RPM LED system complete with dedicated flag indicators. Everything you need right where your thumbs expect it to be.

Will this fit my wheel?

Great question. Before purchasing, you can download the GripBox printable filament template and hold it against your existing wheel to check compatibility. It's a quick and easy way to make sure everything lines up correctly before you buy.

Quality Disclaimer

This wheel has been tested with up to 12 Nm of torque. It should handle higher forces without issue, but this hasn’t been tested, so proceed at your own risk. Its strength depends heavily on following the recommended infill for each part (found in the instructions), your printer’s output quality, and the quality of the filament used. If it fails prematurely due to excessive torque, poor print quality, or incorrect infill settings, I can’t be held responsible for the outcome.

By purchasing this product, you agree to the above.


Design Notes

"Even though the Grip was the first product I had designed for Rival, a wheel-based button box was the first sim racing product I made, way before the Grip. It's something I've wanted to re-visit, but shelved until I had a strong design language and the ability to create something that stood up against off-the-shelf solutions in terms of functionality and price. As soon as I was at a position where I knew I could design such a product, development started and the GripBox was born."
