The mechanical build also sets the DSC Sport Active damper apart from all other class competitors. Offering the finest guide seal, piston, and shim stack arrangement on the market (.01mm guide clearance), the DDA valve incorporated damper withstands heavy load changes with no signs of hysteresis or stiction. Each design is tested on a shock dyno at 17 million cycles and must hold 85% of its damping performance to be approved for production. The result is the world’s most versatile suspension system that provides a previously unheard of combination of race-winning performance on the track and daily driver comfort on the street.
