Description
Sprindex Downhill Coil Spring
Adjustable spring rate coil that's also progressive. Sprindex is specifically designed to have a progressive spring rate for the last 20% of stroke for big hit support and for bikes with a linear linkage design.
Features:
- 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 inchlightweight inch 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
