This is a set of three optional three shoe style 1.1mm clutch springs for Kyosho buggies, and fits the Inferno MP7.5 and Inferno MP777 family of buggies. These are optional springs that you can use to fine tune the way the clutch engages by using different tension clutch springs. The bigger the spring, the stiffer it is and the later in the RPM range the clutch will engage. The smaller the spring, the softer it is and the earlier in the RPM range the clutch will engage.

Kyosho 1.1mm Clutch Springs (3)
I use these on a Kyosho 3-shoe clutch installed on a CRF/Performa Racing P1 7-port Radical engine. The power band of that particular engine is more on the top end, so the one-step heavier springs allow it to rev a bit higher before the clutch shoes engage with the bell, which gets it into the power band quicker.
