Frequently Asked Questions

Will this fit my 2006+ Harley?

No — this nut is for 1991-2005 Big Twin and Twin Cam engines only. 2006 and newer models use different hardware.

What does a compensator sprocket nut do?

It secures the compensator sprocket to the crankshaft. The nut is engineered to stay tight under engine vibration during normal operation.

Is this a direct replacement for the OEM nut?

Yes — this Harddrive nut replaces the factory compensator sprocket nut as a direct fit.

Do I need special tools to install it?

Installation requires a wrench or socket that fits the 1/2" external thread and a way to hold the crankshaft steady while tightening. Consult your service manual for torque spec.
