Wilwood 270-17650 XRZ Sprint 46 Tooth Splined Inboard Wheel Hub Kit

The Wilwood 270-17650 XRZ Sprint inboard hub and adapter kit delivers advanced lug drive rotor mounting for high-performance sprint car applications. Engineered specifically for 8-lug 7.18" snap ring rotors, this hub assembly provides the foundation for a dynamic braking system with superior stiffness and serviceability.

Key Features:

• 46-tooth splined design ensures precise, quality fitment with DMI and Winters 46-spline axles
• 5-bolt rotor plate to hub attachment provides enhanced stiffness and simplified assembly/disassembly
• Optimized rotor plate design features reduced OD to ID dimensions with thicker material for extended life and improved overall rigidity
• Rotor plate can be removed without removing the axle spline saver for easier maintenance
• Innovative hub/lug drive system eliminates bolts attaching rotor to plate, using stainless clips and float clips instead
• Designed for use with Wilwood rotors 160-16923 or 160-17781 (11.75" x 0.81" lug-mount) and radial mount calipers

Important Notes:

• Additional snap ring and wear plates required for rotor mounting (not included with hub kit)
• Snap ring kit with wear plates available separately as Wilwood part number 300-12561

This XRZ Sprint hub represents Wilwood's latest innovation in sprint car braking technology, combining race-proven durability with user-friendly design for competitive racing applications.
