Wilwood's XRZ Sprint 46 tooth splined inboard hub & adapter kit provides a basis to provide dynamic lug drive rotor mounting of 8 lug 7.18 in snap ring rotors. 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. Hub/lug drive version first of new system that requires no bolts attaching rotor to plate with stainless clip and float clips. Designed to be used with rotor 160-16923 (11.75” x 0.81” x 7.18” lug mount) and radial mount caliper. Additional snap ring and wear plates are required for rotor mounting and are not supplied with the clamp kit. Snap ring kit with wear plates is available under part # 300-12561.
