Rebuilding Your Classic Big Twin Clutch
This kit provides the essential friction plates for a clutch refresh on your 1970-1984 Big Twin 4-speed.

Common questions
What components are included in this Energy One clutch kit?
This kit includes friction plates only. Steel plates and clutch springs are not included and will need to be sourced separately or reused from your existing clutch.
Will these friction plates fit my 5-speed Big Twin transmission?
No, this Energy One Performance Clutch Kit is specifically designed for Harley Big Twin models equipped with 4-speed transmissions from 1970-1984. 5-speed models require a different kit.
Can I reuse my existing steel plates with these new friction plates?
Yes, if your existing steel plates are not damaged, warped, or excessively worn, you can typically reuse them. However, for best performance, inspect them carefully during installation.
