XTR-7174 Hub Cap (Replaces 4024)

The Xtractor™ XTR-7174 is a heavy-duty hub cap designed specifically for steer axle applications to deliver superior protection, extended oil life, and faster service. The integrated 3-Stage Magnetic Oil Filter actively traps metallic & particulate debris in the lubrication oil, protecting critical wheel-end components and helping fleets detect potential failures before they happen.

Crafted from premium aluminum, the XTR-7174 resists cracking, corrosion, and damage from road salts and impact. An ultra-clear sight glass with oil level indicator simplifies inspections, while the patent-pending HexThread™ access cap allows quick, clean maintenance—no broken gaskets, no mess.
