Compatible with Lyrik Yari Pike and Revelation with Debonair B1 or C1 spring, the new Tank V4 kit features the new V4 Seal Head, that allows the rider to choose between 4 different configurations with different ratios between lower leg volume and negative chamber volume. Thanks to a slim design there is less friction due to binding and a quad ring provides less friction and less stick slip effect too. You can see for yourself on the graph how much this kit increases the performance of your fork.
Also included in the kit is a token half the volume of the RockShox originals for finer progression adjustment.
* If you use very fast retbound, such as 5-6 clicks from fully open or less, you may experience noisy top out. Furthermore, with this option it is possible to choose only two volumetric configurations
