HUMA-AIR FX Impact Tuning Hammer Spring


This hammerspring has a bit more higher powercurve compared to the MKI hammerspring what will give you more flexibility and power adjustment options when using the powerwheel 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 powerplenum in the MKII
