Wilwood's Gen II Midget 38 tooth splined inboard hub provides a basis to provide dynamic rotor mounting of standard GEN II rotor adapters. Manufactured from high strength aluminum, it provides a lightweight and strong solution for rotor adapter mounting. Gen II hubs offer improved clearance and easier install due to wider rotor adapter attachment bolt spacing.

Wilwood's Gen II Midget 38 tooth splined inboard hub & adapter kit provides a basis to provide dynamic rotor mounting of standard 6 x 5.50” bolt pattern rotors. Hub & adapter kits contain: rotor adapter and dynamic rotor mounting bolt kit. Additional T-nuts and bolts are required rotor mounting and are not supplied with the clamp kit.

Wilwood's Gen II Sprint 46 tooth splined inboard hub provides a basis to provide dynamic rotor mounting of standard GEN II rotor adapters. Manufactured from high strength aluminum, it provides a lightweight and strong solution for rotor adapter mounting. This further improved Gen II hub offer increased clearance and easier install with a new designed stud alignment.

Wilwood’s XRZ Sprint 46 tooth splined inboard hub kit provides a basis to provide dynamic rotor mounting in either a T-nut or lug mount drive style using new 5 x 4.875” rotor adapters. The XRZ Hubs new spline enables easy quality/precise fit for DMI and Winters 46 spline axles. Using new 5 bolt rotor plate to hub attachment for added stiffness and user-friendly assembly/disassembly. Rotor plate has a smaller overall dimension from OD to ID with thicker material to add extended life and improved overall stiffness. Rotor plate can be removed without removing axle spline saver.
