New S54 VANOS Exhaust Hub Upgrade

The factory VANOS hub on the BMW S54 engine is known to develop excessive play where the drive tabs interface with the high-pressure oil pump disk. Over time, this play causes a back-and-forth rattling motion that can lead to the tabs shearing off inside the engine, risking catastrophic 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. This bolt-on fix eliminates the common failure point without opening the VANOS unit or disturbing engine timing.

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