Units for shock valving ?

Does anyone know what the units are for the valving on a bilstein shock? I.e., 255/70 , 170/60 etc.


The stated values that bilstein provide only give me a relative rating between models; I need to know the forces generated. I’m contemplating a shock mount design and I really hate just throwing material at the problem but I hate breaking even more.

 

i think its in newtons, (255/70 would be 2550/700 newtons compression/rebound) but its yield force at x/unit time. So its kind of a useless number without the dyno graph except to compare with other shocks.

if the shock speed is faster or slower than what they rate it at those numbers will be different.

 

Newtons per meter per second maybe?

 

The number is just how the shock reacts at one specific velocity, if its going any other velocity those numbers are different. Also it's rated without a spring.

Look at how the college baja sae teams do this.

Time to break out the old books.

like I said, if you can get the whole dyno graph of the shock it would help but the numbers by themselves dont mean much except in comparison to other shocks from the same company with just the published numbers I would treat it as unitless.

Each company does it differently, some use mm/sec, m/sec, in/sec and that number is taken at a single data point of their choosing. I assume you're trying to figure impact force.
