The ATI crankshaft damper is a steel 7.98-inch, three-ring heavy-inertia unit for Cummins 6.7L engines from 2007.5–2015 that use a reluctor wheel. Its eight-groove configuration and heavy three-ring design address diesel torsional control for these later Cummins models. Choose this damper when replacing or upgrading the harmonic damper on 6.7L Cummins engines with a reluctor wheel to maintain correct crank dynamics.
