Power Tuning Hammer spring for your FX Impact MKI or MKII
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 hybride slugs and we prefer to use this spring over the factory spring when you use the powerplenum in the MKII
Also it makes a perfect combination with our FX Impact Tuning Valve Return Spring
