These are probably the stiffest clutch springs available on the market currently.
This is a single spring. You will need 2 for a 2-shoe and 3 for a 3-shoe clutch.
Don't turn these ones in too far or you'll bend your clutch. These are stiffer than kickstart springs. Probably leave the set screw at the factory setting for safest results or brace your clutch.
Sold INDIVIDUALLY.
***These are NOT the same as other 'blue' springs sold by other sellers. Next batch will be a new color to avoid confusion.
