Those numbers don't match any of mine. These are the three numbers I found on mine.
039-00-445-3
039-00-446-3
039-00-595-3

It never occurred to me the trail edition might have different springs. Following.

Their numbering on these factory springs is strange, on the springs they install on aftermarket units you can decode the numbers as follows. But I don't see there only being a 1lb difference in the upper and lower spring on these. The last number being a 1 or 3 might just be what color it is??

FOX coil-over shocks only use quality, high stress race springs. The springs are a shot-peened, heat-treated chrome-silicon material, designed to give maximum travel and minimum weight. They are preset to ensure they don’t sag over time. TIP: The springs are typically labeled: XXXX-XXX-XXXX For example: 1200-300-0350 The first four digits indicate the spring free length: 1200 = 12.00 inches The middle three digits indicate the spring free internal diameter: 300 = 3.00 inches The last four digits indicate the spring rate: 0350 = 350 lb-in
