Due to fuel prices and tariffs, transportation costs and customs costs, we’ve had to increase the retail price of our Shock Hand Dyno a little. We apologize, but in general we’ve kept the price about the same for almost 9 years now, taking the hit on big increases in materials and shipping since COVID. We will still offer a 15% discount for USA and additional discounts for international orders.

We believe the quality and precision of our Hand Dyno, as well as the positive feedback from our amazing OSO customers, makes it worth the bump up.
