Hi guys,
A few years ago we engineered and built our own hub dyno for our tuning shop. After extensive use, development, and real-world testing, we ended up with a setup we are extremely happy with.
Since then, we’ve supplied this dyno as a DIY build kit to several people, and due to the positive feedback we decided to offer it more broadly.
This kit is aimed at people who are hands-on, technically capable, and looking for a serious high-power hub dyno without spending the kind of money that commercial systems usually cost.
What’s included
Complete DIY hub dyno kit
Klam CFK 360 retarders
Full axle / hub assembly
Hub Adapters 4x98 to 4x140 and 5x100 to 5x140
All required mechanical parts to build the dyno
Detailed “IKEA-style” step-by-step build manual (PDF)
Everything needed to build the dyno is included, no guessing, no missing parts.
Build time
Around 2–3 days
2 people
Straightforward build if you have basic welding and mechanical skills
Controller
We intentionally do not include a controller.There are excellent hub dyno controller solutions on the market (such as Perek Dyno Controller, YourDyno, etc.), and this allows you to choose the system that best fits your workflow and budget.
If you’re interested, have questions, or want more technical details, feel free to comment or send a PM.
