clutch springs?

[Rmk_RDR]

im looking into doing some clutching on my 11 assault rmk and im wondering what exactly does 140-300 mean on a primary and secondary spring? like what difference will the different numbers do? thanks

The small number is the pounds of force at the open dimension. The large number is the pounds of force at the closed dimension. Hope that helps, so if you want a lower engagement you can change to a spring with a lower initial force # and the same final rate, without touching your weights. Just another tuning tool at your disposal.

Thanks! So does the degree of the helix change when it engages as well?
