Springs
- Green/Silver 75-175 Spring: (Engagement 1650-1950 RPM)Â This is the lowest engagement spring we offer but also has a lower spring rate up top than our standard clutch kit springs, so you will lose 100-200 RPM and weights will need to be 1-2 magnets lighter to achieve the same peak RPM.
- Gray/Red 80-200 Spring: Â (Engagement 1700-2000 RPM)Â Excellent spring that is sometimes used in our clutch kits. Â Nice engagement while still keeping the final spring rate (full shift rate) up close to our standard gray/yellow spring.
- Gray/Yellow 85-240 Spring: Â (Engagement 1800-2100 RPM)Â This is our standard clutch spring found in our P90X HD clutch kits with an engagement of 1800-2100 in most cases.
- Gray/White 115-240 Spring: Â (Engagement 2500-2700 RPM)Â Race Spring. Â This spring has the same full shift rate found in our gray/yellow standard primary spring, but has a high engagement of 2500-2700 RPM. Â Keep in mind this spring will be harder on your already weak clutch because of the harsh engagement. Â Great to use with launch control if you want to risk it.
- Gray/Black 105-275 Spring: Â (Engagement 2200-2300 RPM)Â This is a great spring with a mildly higher engagement rate with a higher full shift rate which raises peak RPM around 200-300 RPM. Â Some may find this is a good dune spring if switching back/forth from dune to trail setups... you can install this spring when heading to the sand. Â This spring normally makes up most the RPM lost from the extra sand load, so adjusting weights may not be necessary.
