The factory VANOS exhaust hub on the S54 engine is known to develop excessive play where the drive tabs interface with the oil pump disk. Over time, this imprecise fitment causes a back-and-forth rattling motion that can result in the tabs shearing off inside the engine, risking catastrophic damage or complete engine failure. Unlike other aftermarket solutions that require full VANOS disassembly, retiming, or replacement of the oil pump disk, the Turner Motorsport S54 VANOS Hub Upgrade offers a smarter approach. Our bolt-on fix eliminates the common failure point without opening the VANOS unit or disturbing engine timing.

Our solution involves removing the worn tabs from your stock exhaust hub and installing our precision-fit replacement, which is precision-machined from 4340 steel and hardened to meet OEM specifications. Designed using 3D scanning and CAD modeling, the Turner Motorsport VANOS Exhaust Hub Upgrade provides a tight, interference-free fit into the oil pump disc, completely resolving the issue without unnecessary labor.

VAC's 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 reduce or eliminate the VANOS noise.

Also, this upgraded design eliminates the need for modifying the Pump Ring or having to buy a replacement, which further saves you money!!!
