aFe 461-401003-A PFADT Series SKF X-Tracker Performance Wheel Bearing

The aFe PFADT Series SKF X-Tracker Performance Wheel Bearing is a precision-engineered hub unit designed to deliver the handling accuracy, cornering stability, and durability demanded by high-performance and racing applications. Built around a double-row angular contact ball bearing arrangement, the outboard row features a larger diameter and greater ball count than the inboard row — a non-symmetrical design that maximizes rigidity and load capacity exactly where it matters most.

Engineered as a direct-fit replacement, this unit installs without modification and integrates a speed sensor compatible with factory ABS systems. A black oxide coating provides enhanced corrosion resistance for long-term durability, and flange face run-out is held to less than 10 microns for exceptional precision. Compatible with factory shock absorbers and drop-in ready for performance shock upgrades.

Key Features:

• Non-symmetrical double-row angular contact ball bearing design with more balls at a higher diameter on the outboard side
• Less than 10 micron run-out on flange face for superior precision
• Dramatically improved steering accuracy and dynamic vehicle behavior
• Significantly increased durability over OEM wheel bearings
• Reduced caliper piston knock-back and improved braking response
• Black oxide coating for enhanced corrosion resistance
• Integrated speed sensor — direct plug-in compatibility with factory ABS
• Direct-fit installation, no modifications required
