[20] Heavy Duty Springs

Installing these springs in your 3D clutch will increase the slip torque to about 43 foot-pounds. Made from temperature resistant stainless steel, they can withstand nearly twice the amount of heat as standard before losing their spring pressure. 

If your engine is larger than 212cc or over 15hp, you probably need these springs to prevent clutch slippage.

Six (6) springs included.

To replace springs, you need to compress the clutch, such as with the 3DME service tool. Otherwise, the bolts are under lots of tension. And, you can't thread the bolts back in without compressing the clutch.
