Product Details

The Insane Crank Hub kits are a one-piece design and 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 they believe to be the strongest crank hub kit on the market today!

This crank hub is offered in a 2 pin and upgraded 4 pin design for those looking to push their S55/N55 to the limits while having greater peace of mind. Please keep in mind neither version has had a known failure with 300+ vehicles on the road today and counting. This crank hub has also been tested up to 1000whp without issue.

This kit includes all the necessary components to successfully replace the stock OEM crank hub with the single-piece crank hub. The kit now includes Hardened crankshaft damper bolts at no additional charge.

KIT INCLUDES:

One-Piece Design
Insane Performance CNC'ed Single Piece Crank Hub
Upgraded and Reinforced crankshaft Damper Bolts
