VAC Motorsport S54 Upgraded VANOS hub

  • Sale
  • Regular price $619.00


The VAC S54 VANOS Hub is designed as a direct replacement for the fragile BMW OE Vanos Hub which typically fails due to a broken drive pin. The VAC Hub has an upgraded drive pin design, which is larger in diameter, as well as more material on the outside wall of the pin. In addition, the hub is made from 4340HT Billet Bar and heat treated to the same BMW OE Rockwell Hardness spec. The upgraded design is not only significantly stronger, but the larger diameter Drive Pins also minimize the huge clearance (approximately 1mm) that was in the original design by BMW, and reduces the clearance to 0.2mm. This is critical in helping greatly reduced or eliminate the VANOS noise.  This part is designed to be used with the OEM sized vanos disc holes.
