S54 VANOS HUB Solution
From Ultimate Bimmer Service of Dallas, Texas on .
We are Dallas' most tenured/trusted BMW shop and have tried several solutions over the last 12 years in business. Hands down Armand and the VAC team have it whooped and their products perform as advertised, they are our sole provider for S54 hubs when our customer need them. We would never sell any product we did not stand behind with our own BMW's!
Highly recommended fix for VANOS Hub cracking
From John Payne of Westlake, Australia on .
The issue of tabs cracking on the exhaust hub of the S54 engine has been well documented. Of the options available to solve this issue, the VAC Motorsports Hub Upgrade is the best - especially if you intend to stress the engine on the race track. The entire hub is made from stronger material and the tabs are thicker to give more strength. This extra tab thickness means that they fit into the holes of the VANOS Oil Pump Disk snugly thus reducing chatter/backlash which has long been suspected of causing the tabs on the OE Hubs to break. A real improvement to a great engine.
Great Replacement Hub
From Chris Ruel of Indianapolis, Indiana on .
Got this to replace a broken hub. Very nicely machined. Fit stock pump disk holes with barely any discernible “play”. No need for a redrilled pump disk.
