S55 CRANK HUB — DON’T WAIT FOR THE FAILURE. 🔩
The BMW S55 is an incredible engine — but when you start increasing boost, power and RPM, the factory crank hub becomes an area that deserves serious attention.
A crank hub failure can result in timing deviation, loss of engine synchronization and, in the worst case, catastrophic engine damage.
This F80 M3 came in for a Gintani CrankHub Upgrade, giving the S55 a significantly more secure solution for high-performance applications.
🔧 GINTANI CRANKHUB UPGRADE
• Positive crank hub retention
• Reduced risk of crank hub movement
• Designed for high-power S55 applications
• Precision installation with timing verification
• Ideal for tuned and track-driven S55s
If you're already spending money on boost, fuel, cooling and drivetrain upgrades, don't overlook the component that keeps the engine's mechanical timing where it should be.
More power demands more reliability.
Build the power.
Secure the timing.
Protect the S55.
