Do they spec 'front' or 'rear' valve codes? Remember that most 'front' shocks are at close to 2 to 1 leverage ratio, and most 'rear' shocks are at a 1 to 1 ratio, or close. Factor in the weights and it is clear that the typical front shock need 4x the valving resistance as compared to a rear shock (very wide liberal estimate for discussion) While they do offer adjustable valving, it is all in a set range. So , our job is to use what is available, test it on a shock dyno, set the valving range and then design a way to use off the shelf parts and make them work to the best of their ability.
From what I read just now, shock leverage ratio is the ratio of wheel movement to shock shaft movement -- I might be misunderstanding though, because the only way to get a 1:1 ratio would be to have a shock mounted along the axis of axle motion, correct?
