ATI Damper - 7.074in - Alum - 7 Grv - Toyota 1Gr-Fe - 10 Percent UD Pulley - 1Pc

This is the ATI 918466 crankshaft damper, specifically made for Toyota 1GR-FE engines. It's a well-built aluminum unit designed to control torsional vibrations from the crankshaft, which is crucial for engine longevity and smooth operation, especially in performance applications. This damper also includes a 10 percent underdrive pulley, meaning it spins the accessories like the alternator and power steering pump slightly slower than stock. This can lead to a small but noticeable improvement in throttle response and frees up a bit of parasitic drag from the engine.

Crafted from aluminum, this damper is lighter than a stock cast-iron unit, which can help reduce rotational mass. It features seven grooves for accessory belts, ensuring compatibility with most setups. The 1-piece design is straightforward to install, replacing your original damper directly. By effectively absorbing harmful vibrations, this ATI damper helps protect your engine's crankshaft and main bearings from premature wear, making it a solid choice for any 1GR-FE build where reliability and performance are key.
