bgm PRO clutch springs are manufactured in Germany and are subject to continuous quality control. The used material Oteva70® makes the springs block stable and true to size. The spring does not deflect sideways until it is blocked. When unloaded, it returns to its original length.
The clutch spring retains its full spring force.
The spring rate is significantly tighter than that of an original spring.
Ideal for performance upgraded engines.
