Crank Hub Upgraded Kit For S55/N55 BMW M3/M4 F8X

Application
The complete N55, S55 complete crank hub solution that does NOT require
the crank to be drilled for pins. The hub uses our proprietary “Spline Lock”
technology that uses high tolerance machined splines which press into the crank,
and positively lock the hub to the crank. IF you are tuning your N55 or S55 or using hard on track,
we recommend fitting this product to ensure yourself against an expensive engine failure
if the OE crank hub were to fail.
