Frequently Asked Questions

What's included in the kit?

The sprocket lock nut and integrated lock plate, plus all mounting hardware needed for installation.

Will this work on my 2005 Dyna or pre-2007 Softail?

This kit is designed for 2006+ Dyna and 2007+ Softail and Touring models. Older models may use different sprocket hardware — verify your year before ordering.

How does the lock plate work?

The integrated lock plate prevents the nut from rotating and loosening due to vibration. It can be positioned in nearly any angle to clear other components on your frame.

Do I need special tools to install this?

Basic socket wrench and possibly a lock plate tool are recommended. Torque specifications follow Harley-Davidson service manual guidelines for your model year.
