It's quite simple, really... Radial Dynamics is here to help you gain the highest level of hydraulic performance, reliability, and safety out of your vehicle by delivering high quality components and higher quality know-how.

Whether you drive a purpose-built off-road race truck or a Jeep made for cruising the trail, all things grind to a halt when hydraulic systems fail. That's why Radial Dynamics takes an engineering-based approach to hydraulic system design and diagnostics. 

Radial Dynamics was born at the intersection of my passion for motorsports and more than a decade of successful fluid systems engineering. To witness customer success stories resulting from quality, innovation, and education keeps me driven every single day. 


Fully hydraulic steering systems in particular are a Radial Dynamics specialty. Although hydraulic steering systems are relatively simple hydraulic circuits in the world of fluid power, there are many seemingly minor design considerations that are often overlooked or misunderstood which can result in poor performance, premature failure, and worst case scenario, risk to personal safety. 

This is not just another e-commerce parts store. This is your go-to source for hydraulic steering solutions and support you can trust.

Our History:

It was one of those "right place, right time" stories that occurred at the local off-road park on a chilly weekend in late 2017. The Big B Motorsports Ultra4 race team had outfitted diagnostic sensors throughout their steering system because they had a problem: they were running all the best of the best equipment on their vehicles, yet, they could not keep a steering pump alive for longer than one race throughout the season.

While simply tagging along for the experience, fellow racer and fluid systems engineer Eric Amato listened in on the technical details and quickly realized that these steering systems had serious fundamental challenges needing to be addressed.

Radial Dynamics was subsequently founded in January 2018 to focus on re-engineering of hydraulic steering technology and development of the patented Vortex Reservoir which led Eric to a Top Finalist spot in the 2019 SEMA Launch Pad competition for young entrepreneurs. Since then, Radial Dynamics customers have seen enormous success in a variety of motorsports disciplines including Ultra4 (King of the Hammers), mega trucks, monster trucks, rock crawlers, and rock bouncers.


Committed to Excellence


To support rapid business growth and enable the highest level of service, Radial Dynamics invested in purchasing a 5,300 square foot commercial facility in 2022 which now serves as company headquarters. The location is in Greenfield, Massachusetts just minutes from the junction of MA Route 2 and Interstate 91. We are a 2-hour drive from Boston, MA and 1-hour drive from Hartford, CT. 

In addition to warehousing/fulfillment and engineering, the facility features a clean, dedicated workshop for assembling, servicing, and testing of power steering components. In-house testing capabilities include a custom 22 HP power steering pump dyno as well as various hydraulic power units, valves, and plumbing used to function test other high pressure steering items such as pressure relief and steering control valves.
