With this tester you are able to not only check old shocks, but compare new shocks for consistency. All you need is an air compressor that can maintain 100 psi.
A handy conversion chart allows you to discover each shocks' valving and draw it on a graph. For those of you with a computer, software is included to save or print each shocks' graph. Completely portable. Use it at home or in the trailer.
For Rod End style shocks only.
