PRIMARY SPRINGS

• Light Blue/Yellow 55-155: (Engagement: 1800-2000 RPM) This is the standard spring in the XPT clutch kits.
• Light Blue/Green 70-155:  (Engagement: 2000-2100 RPM) This spring works great with slightly higher engagement.
• Light Blue/Red  85-180:  (Engagement: 2100-2200 RPM) Stiffer end rate producing around 150 more peak RPM than the above springs ending in a 155 rate.
• Teal 90-225:  (Engagement: 2000-2200 RPM) Stiffer end rate will pick up around 200 RPM peak. This is a good spring for the dunes as well that is a little better for slower riding than the solid light blue.  This normally picks up the RPM lost by the high load of the sand and paddle tires making it an easier choice to swap the spring rather than change weights when going from tires to paddles.  This all depends on your tire to paddle size, weight, and terrain.... you may still need to adjust weights.  
• Solid Light Blue 110-250:  (Engagement: 2500-2700 RPM) This is the race engagement spring with a stiffer end rate raising peak RPM about 200-300 peak over the blue/yellow spring, so make sure you can install another 2 magnets in your AA clutch arms when installing this spring.  Many will install this spring for dune riding instead of changing weights as it may pick up enough RPM needed.  This all depends on your tire to paddle size, weight, and terrain.... you may still need to adjust weights.
