ATI Super Damper Balancer for 2014-2018 GM Truck (Silverado/Sierra) L83/L86
NOTE: The standard ATI part number 918645 kit does NOT include the front serpentine drive pulley. However, we do include the required serpentine drive pulley, which is what you are selecting from the drop down menu.
Are you looking for maximum engine protection and performance for your serpentine belt application? These ATI Super Damper serpentine harmonic balancers contain grooves for serpentine belts machined into the outer damper shell. The dampers come standard with six outer grooves for standard OEM drive systems. Specifically designed for high-rpm engines, they're tuned to eliminate the harmful crankshaft harmonics that cause parasitic horsepower loss. They're tunable in the field, rebuildable, and extremely efficient at all rpm.
