Call Fred at Pro and have him explain it to you. Great guy. That or call a company like CSI(Garret),Advanced(Cory) or Indy Race Parts(Bernie).
All of the companies are a little diifferent in terms of what their numbers represent or how they dyno their shocks.
One of the reasons that the smaller shock rebuilders/companies were started is because of the quality control problems the bigger companies like Carrea and Pro had. As shocks have evolved; they have become the biggest tuning device on the car.
