FAQ
Is this assembly pre-bled and ready to install?Yes—master, line, and slave arrive pre-filled and pre-bled for a quicker install and consistent pedal feel.
Will it improve pedal feel with a performance clutch?Heavy-duty internals and full replacement of master/line/slave help maintain proper release and pedal effort with higher clamp-load clutches.
How do I confirm whether I have an NV5600 or G56?Check the transmission tag or case design. 2005–2018 is typically G56; some early 2005 may be NV5600. Choose clutches accordingly (see Recommended & Alternatives above).
What else should I replace while I'm in there?Inspect/refresh the fork, pivot, and spring for best feel and longevity: pivot, fork, spring.
