Genesis Stacked Spring

The Genesis Stacked Spring

This system allows for adjustable dual rate spring performance.

Two springs are stacked and deflect at a combined rate. At a point determined by the contact position of the stop nut on the threaded body of the shock absorber and the separating slider between the springs… one spring stops deflecting.

This allows only the other remaining spring to deflect, it will do so at its own single rate.

This system enables a team to time the transition point on the race track between a relatively soft combined rate for optimum weight transfer/wheel movement and a higher secondary rate for maximum compliance and wheel/tire loading.

Formula for combined rate calculation:

"A" spring multiplied by "B" spring….take this number and divide it by the sum of "A" and "B" and you will get the combined rate.

Example:

500# rate spring

600# rate spring

500# rate multiplied by 600# rate… divided by 500# + 600# will have a combined rate of 272.73# and a secondary rate of 500# (assuming the 600# rate is mechanically locked out).
