# Determining damping coefficient of a shock

## Determining damping coefficient of a shock

(OP)
Have a couple shocks that I want to test for their damping coefficients. Does anyone know any good testing methods that can be done without using highly sophisticated measuring devices to determine the damping coefficient?

### RE: Determining damping coefficient of a shock

Which one of the usual 4 damping coefficients are you referring to ? (jounce, jounce blowoff, rebound, rebound blowoff).

### RE: Determining damping coefficient of a shock

(OP)
Sorry, I wasn't being very specific. I would like to test for all 4 of the damping coefficients. I don't have a shock dynamometer handy so I'm having difficulty figuring out how I can do this.

### RE: Determining damping coefficient of a shock

(OP)
Also I would like to add that the shocks are mono tube nitrogen charged.

### RE: Determining damping coefficient of a shock

Shock dynamometer.

You can't measure crankshafts and connecting rods for oil clearance using a tape measure. Same concept. If you want to make the right measurement with the right degree of accuracy, you need the right measuring tool ... and in this case, that's a shock dyno.

Backyard methods like installing it on a car and jumping up and down on the bumper will tell you whether it has some damping, or none.

### RE: Determining damping coefficient of a shock

(OP)
I had a feeling that was my only option. That sucks Thanks for the replies anyways! I guess I'm going to have to look for a local shop that will provide shock dyno services.
