This hammer-spring has a slightly higher power-curve compared to the MKI hammer-spring what will give you more flexibility and power adjustment options when using the power-wheel of your FX Impact.
It’s great when you want to tune your FX impact for slugs or hybrid slugs and we prefer to use this spring over the factory spring when you use the power plenum in the MKII
