Product Description
ATI 917286 Super Damper LS Harmonic Balancer with A/C Pulley
OEM-Diameter 7.4-Inch Steel Damper | 6-Rib Drive & 4-Rib A/C Pulley | Truck Accessory Spacing
Control harmful crankshaft vibrations in your street, performance or racing LS engine with the ATI 917286 Super Damper. Designed for compatible GM trucks, SUVs, Camaro SS models and LS swaps using truck accessory-drive spacing, this rebuildable harmonic balancer combines an OEM-diameter 7.4-inch steel shell and hub with a 6-rib accessory drive and integrated 4-rib A/C pulley.
Key Features & Benefits
- Controls Torsional Crankshaft Vibrations: The ATI Super Damper is engineered to dampen harmful engine harmonics throughout the RPM range. This provides additional crankshaft protection for performance and racing combinations while replacing aging factory balancers whose outer shells can loosen from the hub over time.
- OEM-Diameter Truck Spacing: The 7.4-inch-diameter configuration maintains OEM-style sizing for compatible LS applications using truck accessory-drive spacing. Its 6-rib main drive and integrated 4-rib A/C pulley support the supplied GM truck, SUV, Camaro SS and LS-swap applications.
- Steel Shell and Hub Construction: ATI manufactures the 917286 damper with a steel outer shell and steel hub for demanding street and competition use. A black zinc chromate finish provides the assembly with ATI’s recognizable performance appearance.
- Exceeds SFI 18.1 Specifications: Built to exceed SFI 18.1 specifications, this Super Damper is suited for LS-powered vehicles used at the track as well as high-performance street builds. Its tunable and rebuildable construction allows the damper to be serviced rather than treated as a disposable component.
- 360-Degree Timing Marks: Laser-engraved timing marks extend around the full 360 degrees of the damper shell, providing a clear crankshaft-position reference during engine setup and diagnostics. The permanent engraved markings remain integrated into the steel shell for convenient timing reference.
Notes
- Designed for applications using GM truck accessory-drive spacing.
