Ski-Doo Primary Spring Chart
That chart was made up from "The Hotrod Sled Shop Inc."'s chart....
The different color labeling is due to the different spring suppliers listed.
WE COMBINED SEVERAL MFGS. OF DRIVE SPRINGS INTO ONE CHART TO HELP TUNERS DECIPHER WHAT THEY ARE USING OR LOOKING FOR. WE DO NOT STOCK ALL OF THESE SPRINGS AND SOME OF THESE SPRINGS ARE NOT AVAILABLE ANYMORE!
DALTON $29.95, STRAIGHTLINE $24.95, SKI-DOO $26.95 OR *$31.95, ERLANDSEN $24.95
PREFIX'S: GP-GOODWIN, ER- ERLANDSEN , ST-STRAIGHTLINE, DT-DALTON, COLORS ONLY ARE OEM SKI DOO, T-TITANIUM
GR is Ski-Doo, Goodwin Performance and Erlandsen green
GRY is Dalton's Grey
GN is I believe a misprint/mistype and represents Ski-Doo Green... I see it used for the 200 lb start Ski-Doo spring and I know it is a green spring.
