Insane Performance - BMW One Piece Crank Hub || N54, N55, S55

Our Single Crank Hub kits are designed and manufactured in Lithuania and made from a solid block of thermally absorbed, heat treated steel and milled on a 5 axis precision CNC machine to create what we believe to be the strongest crank hub kit on the market today!

Our crank hub is offered in a 2 pin and upgraded 4 pin design for those looking push their S55 to the limits while having greater peace of mind.  Please keep in mind neither version has had a known failure with 1200+ vehicles on the road today and counting.  Our 2 pin crank hub has also been tested up to 1000+ whp without issue.
