Protect your BMW engine with the VAC Motorsports Crank Seal Guard for N54, N55 and S55 engines. This front main seal guard, precision machined from 6061 billet aluminium, is designed to stop serpentine and auxiliary belt ingestion through the crank seal. A proven solution for BMW N54, N55 and S55 belt ingestion issues, it safeguards your crank hub, preserves engine timing and helps prevent catastrophic engine damage.
On N54, N55 and S55 engines, a thrown or frayed auxiliary belt can be drawn past the crank seal into the crank hub area. When that happens the belt is shredded, contaminates the oil pickup, reduces oil pressure and can lead to engine timing disruption and full engine failure. The VAC Motorsports Crank Seal Guard creates a precise barrier with self-locating pilots that seal the crank hub bore and maintain even, minimal clearance around the hub for maximum protection.
