01+ GM 6.6L Duramax DHD Harmonic Balancer Installer

DHD's heavy duty balancer installer is a must for customers installing aftermarket dampers. Unlike the OE balancer, most performance Duramax dampers are press fit on the crankshaft. This precision fit requires precision installation! DHD's installer utilizes a self centering sleeve to help guide the balancer on square, and a heavy 18mm stud to provide the pressing power required.
