GM LS3 7.480 Harmonic Damper - SFI

The ATI Supercharger Super Damper integrates the protection of the Super Damper within the crankshaft blower pulley. It features external belt drives for various blower belts, eliminating the need for separate crank-mounted blower pulleys. Crank hubs are available for all engines with 25 tooth x 20mm 8mm HTD drive pulleys for dry sump or fuel pump drives. All hubs have dual keyways and are available in custom lengths for cam belt drive setups. Numerous pulley offsets are available to keep the blower drive close to the engine to reduce bending moment to the crankshaft nose. SFI-certified.
