HardDrive Finned Headbolt Covers Silver | 1999–2017 Harley Twin Cam

Add classic performance styling to your Twin Cam engine with H

These are HardDrive silver finned headbolt covers designed to slip over the existing head bolts on Harley-Davidson Twin Cam engines from 1999 through 2017, adding classic finned styling to the top end of the motor.

The finned design evokes vintage performance hardware and complements polished, chrome, or black engine finishes. These covers provide a simple bolt-on upgrade that enhances engine detailing without permanent modification.

This set replaces the standard factory headbolt appearance and is made for correct fitment on Twin Cam motor top ends where headbolt covers are used. Boomers Bike Shop chooses parts we trust for real-world use and classic styling on rider, custom, and restoration builds.
