Universal GM Chrysler Mitsubishi Harmonic Damper Pulley Puller Kit
Removes harmonic dampers and crankshaft pulleys without damage using controlled leverage. This kit gives you the mechanical advantage needed to break stubborn fasteners and extract pulleys cleanly. Works across GM, Chrysler, and Mitsubishi platforms with universal adapter compatibility.
Will this work on my specific damper size?
The three-jaw head and reversible adapter set are designed to handle a range of damper diameters across GM, Chrysler, and Mitsubishi engines. Test the jaw spread against your damper before applying pressure to confirm clean contact on all three points.
Do I need to drain coolant or remove the radiator first?
That depends on your engine bay layout. The puller's long reach helps keep it clear of hoses, but you may need to move or remove the radiator fan shroud for access. Check your service manual for damper removal steps specific to your platform.
What if the damper won't budge?
Turn the center bolt slowly and steadily — do not jerk or hammer it. If resistance is extreme, soak the damper with penetrating oil for 30 minutes, then try again. The tool is designed to generate leverage over time, not brute force in one turn.
