For 0-3000 ft 85 gram weights purple spring and 44/40 helix
for 3000-6000 ft 83 gram weights yellow white spring and 36 degree helix.
I got this off a online parts book from a dealers site they didnt list 6-9000 ft but from memory only the weight changes 80grams i believe and 75 for 9000 plus ft. Hope this helps
