The Extreme Rage Spyder spring kit is composed of 4 color coded striker springs. A very useful aide when tweeking the velocity of your Spyder when old springs have worn out or when velocities become erratic due to extreme weather changes. Combine it with another kit and you'll have an almost endless choice of main spring tweeking tensions when tuning your Spyder.
Blue – Light Weight
Red – Medium Weight
Orange – Heavy/Medium Weight
Green - Heavy Weight
This spring kit works with all Spyder, Psycho Ballistics, Piranha, Dragun and Rebel markers. Basically just about every Spyder or Spyder clone stacked tube blow back marker you can think of.
**These sriker springs are too long for the RSX, VS2 and VS3 markers that use the Kingman balance valve shorty striker
