ATI Damper - 7.074in - Steel - 1987 Buick Grand National Turbo V6 - Ext Bal - 3 Ring

This ATI 7.074-inch steel crankshaft damper is built with a 3-ring design, a key feature for managing torsional vibrations in high-performance engines like the one in your 1987 Buick Grand National Turbo V6. Because it's designed for external balance, it's specifically suited for applications where the factory balance shaft has been removed or modified, ensuring smooth operation and protecting your engine's crankshaft from damaging harmonics. The steel construction offers a solid foundation for durability under demanding conditions.

ATI is well-known for making robust engine components, and this damper is no exception. The multi-ring setup works to absorb and dissipate the twisting forces that occur with every combustion cycle, especially under boost. This helps prevent crankshaft fatigue and potential failure over time. The 7.074-inch diameter is a specific fitment for the Grand National's engine bay, and the external balance configuration means it's intended for builds that have been optimized for performance beyond stock specifications. Proper installation is crucial for any damper; ensure you follow the manufacturer's instructions carefully, paying close attention to the torque specifications for the crank bolt and any associated hardware.

When you're pushing your Grand National's turbo V6, managing the stresses on the crankshaft is paramount. This ATI damper is a well-built component designed to handle those stresses, offering peace of mind and helping to ensure the longevity of your engine's rotating assembly. It's a solid choice for enthusiasts looking to protect their investment and maintain reliable performance.
