Wilwood 270-17657 Sprint Inboard Dynamic 46 Tooth Hub Assembly

Wilwood Disc Brakes has just launched an XRZ rotor adapter and axle spline clamp in a hub kit to mount floating rotors. The result is increased stiffness and simplified rotor and adapter service by leaving the spline saver in place. The new XRZ Splined Hub Kits allow a dynamically mounted rotor to an adapter to be installed outboard of the new 46-spline XRZ Hub Axle Clamp, which has been designed for a precision fit on DMI and Winters axles. 

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.
