Collection: ATI / Fluidampr / Adapters

Unleash the true potential of your engine with ATI Super Dampers and Fluidampr harmonic balancers—two leading solutions trusted by racers and performance enthusiasts worldwide.

ATI Super Dampers are engineered for maximum vibration control and durability, utilizing a multi-piece design with encapsulated elastomer rings that absorb crankshaft harmonics across a wide RPM range. Whether you’re on the street or the track, ATI’s precision construction ensures smooth operation, increased component lifespan, and the reliability you need under extreme conditions.

Fluidampr takes a different approach, using an internal inertia ring suspended in a viscous silicone fluid. This cutting-edge technology adapts instantly to RPM changes, providing consistent damping and reducing harmful torsional vibrations. Fluidampr’s maintenance-free design is ideal for high-performance builds, offering improved throttle response, smoother operation, and extra insurance against engine wear.
