RD2 Damper and Shock Dyno Machine

CTW introduces the RD 2, the Rotational Damper dyno for the racing community for testing shocks.

RD2 is 2HP machine with a peak stroke of 2.0″ and peak speeds over 30 in/sec.

The RD2 uses CTW-Probe Analysis software to allow the user to create and run Tests of various velocities on one of three strokes to collect force data that is presented in various industry-standard graphs. The RD2 is a compact, lightweight machine that is designed to be structurally sound where loading is applied based on FEA analysis. Measurements are taken based on the line of actuation to ensure only the damper or specimen result is recorded.
