Genuine Infiniti QX55 Crankshaft Seal

The Infiniti QX55 Crankshaft Seal keeps engine oil from leaking out past the crankshaft and helps keep engine parts lubricated. The Crankshaft Seal employs a tough steel shell fused to a flexible rubber lip that hugs the shaft tightly. Thus, it prevents leaks under normal driving and even in bursts to redline. The design is applied throughout the Infiniti range for rock solid reliability and silky smoothness. Since its first arrival in showrooms, every QX55 takes the same Crankshaft Seal size. This means that Infiniti drivers who switch between model years don't have to worry about extra hardware. The Crankshaft Seal halts oil loss to enable the turbocharged QX55 engine to operate more freely, reduce friction heat, and protect peak fuel economy, reducing emissions and keeping daily safety high as key bearings remain fully cushioned under stress. If this part ever wears out and leaves droplet traces around the lower timing cover, fitting a new Crankshaft Seal will restore the circuit seal immediately. As a result, the level of the Infiniti motor oil remains constant, preventing breakdowns and evading costly internal repairs. The Crankshaft Seal's tough nitrile rubber on older units and high-performance fluoroelastomer on current builds provide outstanding heat and chemical resistance, enabling the QX55 to tackle stop-start traffic, steep climbs, and long highway pulls without loosening this vital grip. Thanks to a well-seated Crankshaft Seal, Infiniti fans can expect things like quiet running, no mess under the car, and bigger service intervals, all of which endorse why the QX55 is a benchmark in the segment and even more. Through its factory fit, common spec across all sporty QX55 versions and proven performance, this Crankshaft Seal gives Infiniti owners the confidence of an engine that won't leave you stranded, one that will stay clean, efficient, and ready for the road.
