Sprindex Coil - 75x162mm

Adjustable base spring rate by changing the length of effective coils
 
Includes spring, adjuster, and 5 Delrin performance adapters that allow the spring to spin while compressing and also adapt to a variety of shocks on the market
 
Coil is made of super high tensile spring steel similar to "lightweight" springs (which is why Sprindex is lighter than regular springs) in order to handle the stress of the system when adjusted to its highest spring rate setting, as well as reduce coil mass
 
Behaves like a regular coil that has a spring rate the same as your adjusted Sprindex spring rate. Adjusting your Sprindex does not change the length of the coil and so does not change your preload. Preload is adjusted normally and with the threaded ring that came with your shock
 
The first 80% of the stroke has a linear rate while the last 20% of the stroke has a progressive rate to help smooth bottom out
