The VAC Motorsports Crank Seal Guard, made of 6061 Billet Aluminum, prevents your serpentine belt from being pulled into your engine, a common problem amongst BMW N54, N55, and S55 Engines. Without a crank seal guard, the serpentine belt on N54, N55, and S55 engines is commonly sucked into the crank hub area past the crank seal, where it enters your engine and disrupts engine timing. When this occurs, the belt is shredded and clogs engine oil pickup, starving the engine and reducing oil pressure, causing catastrophic engine failure and thousands of dollars worth of damage. VAC Motorsports’ Crank Seal Guards are precision machined for perfect fitment and provide rigidity and maximum protection. We designed our guard with self-locating pilots to perfectly seal the crank hub bore and provide even, minimum clearance around the crank hub. Installation Hardware included. Made in the USA.

Multi-Layer Steel gaskets are comprised of multiple embossed layers of both proprietary high-temperature coated and uncoated stainless steel, requiring less clamp load, creating less bore distortion, and conforms load distribution across the sealing area. The embossed outer layers of our head gaskets meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The MLS Gasket (Multi-Layer Steel) features an active combustion seal on multiple layers. The stainless steel outer layers utilize FKM (Viton®) rubber coating, a high-temperature and chemical-resistant polymer. A topcoat of PTFE aids in resistance to fret and increased cold sealing.
