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.
