Medium Contra Spring for 3-shoe Clutch - Blue

Blue springs. Coil thickness: 2.3mm

These contra springs are harder than the yellow ones.

Working principle: a thicker spring wire will make the clutch grab at higher revs.
A thinner spring wire will make the clutch grab at lower revs. When the clutch grabs at higher revs, the 'take-off' will be snappier and punchier.
It is best to try all sizes to find the one that is best suited to your vehicle.

These springs make the clutch grab at higher revs when starting and at the exit of a turn when rolling on the gas.
