ATI Damper - 7.074in - Alum - 7 Grv - Nissan VQ35 VQ37 - Dry Sump Cars Only - OEM Drive

This is the ATI 918565 crankshaft damper, specifically made for Nissan VQ35 and VQ37 engines that are set up with a dry sump oiling system. If you're building a high-performance VQ engine for racing or track use where a dry sump is essential for oil control, this damper is a key component for keeping your crankshaft running smoothly and preventing torsional vibrations. It's designed to work with the OEM drive belt setup, ensuring compatibility with your existing accessory pulleys.

ATI is well-known for making robust engine components, and this damper is no exception. It's constructed from aluminum for a good balance of strength and weight, measuring 7.074 inches in diameter. The damper features 7 grooves, which is important for proper belt engagement and power transfer to your accessories. Dampers like this are critical for preventing harmonic vibrations that can occur at higher RPMs, which can otherwise lead to crankshaft fatigue and potential failure over time. By absorbing these vibrations, the damper helps protect your engine's internal components and allows it to perform reliably under demanding conditions. This unit is designed for dry sump applications only, meaning it's intended for engines where the oil pan has been replaced with a dry sump system, which is common in dedicated race cars or highly modified street/track vehicles.

When installing this damper, ensure you follow the manufacturer's recommended procedures, especially regarding crankshaft pulley bolt torque and any specific alignment requirements for dry sump systems. This damper is a direct replacement for the factory unit in the specified applications and is built to withstand the rigors of performance driving.
