We recently did our own independent side by side spring rate test w/ the Ferrea Dual spring. Below are the results, and we were even more impressed than we initially thought. What you are looking at below is the rate of the spring in pounds @ different compression heights.

  • Rate @ 1.550"
  • Brian Crower = 80lbs
  • Ferrea Dual = 90lbs
  • Rate @ 1.339
  • Brian Crower = 140lbs
  • Ferrea Dual = 140lbs
  • Rate @ 1.200
  • Brian Crower = 175lbs
  • Ferrea Dual = 175lbs
