ATI Damper - 6.78in - AL - 6 Grv - 10 Per UD - LS1/2/3/6/L76 - 97-13 28T 8mm HTD Drive Rear - 3 Ring

This ATI damper kit includes the 6.78-inch aluminum crankshaft damper itself, featuring a 3-ring design and a 28-tooth, 8mm HTD rear drive. It's configured with 6 grooves for accessory belts and is set up for a 10% overdrive, meaning your accessories will spin 10% faster than the crankshaft. This setup is specifically made for LS1, LS2, LS3, LS6, and L76 engines produced between 1997 and 2013, covering a wide range of popular GM V8 platforms.

Crankshaft dampers are crucial for managing the torsional vibrations that naturally occur in an engine's rotating assembly. Without proper damping, these vibrations can lead to premature wear on bearings, the crankshaft itself, and other critical engine components. ATI is well-known for building robust dampers that offer improved protection. This particular unit uses a 3-ring design, which is a common and effective way to distribute the damping forces across the face of the damper. The aluminum construction helps keep weight down, which is always a consideration in performance builds. The 6-rib pulley system is designed to handle the demands of multiple accessory drives, and the 10% overdrive is a popular choice for enthusiasts looking to ensure their accessories, like alternators and power steering pumps, keep up under higher engine speeds.

When installing this damper, remember that it's a direct replacement for your stock unit, but it's always a good idea to consult the manufacturer's installation instructions. Ensuring the crank snout is clean and free of debris is key for a proper fit. This damper is a solid option for anyone rebuilding or modifying their LS engine and looking for reliable harmonic control and accessory drive capacity.
