ATI Damper - 7.074 - 6 Grv - AL - 5.29 Od - Toyota Supra - 94-98 JZ80 - 10 Percent UD - 2 Ring

This ATI 7.074-inch crankshaft damper is built with a solid aluminum housing and features a 10 percent underdrive pulley design. It's specifically made for the 1994-1998 Toyota Supra JZ80 model, addressing the unique needs of its 2JZ-GE and 2JZ-GTE engines. The damper's primary job is to reduce torsional vibrations from the crankshaft, which can cause stress and potential damage over time, especially in high-performance applications. By absorbing these vibrations, it helps protect the crankshaft and other engine components, contributing to overall engine longevity and smoother operation.

The 10 percent underdrive pulley means the accessories driven by the crankshaft—like the alternator, power steering pump, and water pump—will spin 10 percent slower than stock. This can slightly reduce parasitic drag on the engine, potentially freeing up a small amount of horsepower and reducing the load on those accessory systems. The damper incorporates two rings for enhanced dampening capabilities, and its 5.29-inch outer diameter is designed to fit within the Supra's engine bay. The 6-groove serpentine belt configuration ensures compatibility with the factory or aftermarket belt system.

When installing this damper, it's important to ensure the crankshaft snout is clean and free of debris. Proper alignment and secure mounting are critical for the damper to function effectively and safely. This ATI damper is a well-built component designed to handle the demands of modified or performance-oriented 2JZ engines, offering a balance of vibration control and accessory drive modification.
