About us

Suspension Technologies USA is a mission-driven, high-performing motorcycle component engineering company creating today's best Harley-Davidson(r) motorcycle shocks and front fork cartridges. We've demonstrated our commitment to the American motorcycle industry by providing the most innovative Harley shocks available and the best customer service you can find. Our team utilizes a true monotube shock design with custom valving in the piston and base valve, offering the highest level of performance. Inspired by NASCAR, NHRA, and Road Racing, our products are designed to stand the test of time and provide the best performance available on the market. We use a low-pressure nitrogen gas design in our signature Black Hills series Harley shocks to enable seals to move more easily, meaning a smoother, more efficient ride. In addition to our shocks, we also manufacture Harley front fork suspension systems that incorporate a truly progressive wound spring and a cartridge fork design for superior oil management and performance. All of our products are Dyno-Tested and matched for balance and predictability.
