The Shocktech Spyder spring kit is composed of 4 main springs that work primarily with the striker. No other kit available gives you so many choices of striker spring tensions. This is an especially good choice when utilized with the Maddman Rocket valve that has no need for valve spring alternatives. Combine it with another kit and you'll have an almost endless choice of main spring tweeking tensions when tuning your Spyder.
Silver – Light Weight
Green – Medium Weight
Gold – Heavy/Medium Weight
Red - 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
