Part No: HD-1

The HD-1 Harmonic Damper Installer is a high quality, precision-machined tool that enables the proper press-fit of all harmonic dampers and is designed for a lifetime of use.

Manufactured from alloy steel and fully heat-treated the HD-1 incorporates a Torrington thrust bearing and washers for smooth, effortless damper installation.

Improper installation of any performance harmonic damper may damage the crank snout and damper hub and in most cases will void any warranties for those parts.

The Kit includes two Mounting Bolts and Thread Adapters for use on crankshafts that are tapped for 3/8", 7/16", 1/2", 5/8" and 3/4" SAE threads. Metric Thread Adapters are also available.
