THE PROBLEM EVERYONE'S IGNORING
"Oil contamination causes component wear which generates more contamination. This chain-reaction-of-wear causes higher friction, higher fuel consumption, and leads to premature component replacement."
- SAE Review of Lubricant Contamination, 1998
We built something to Solve The Problem
A hub cap that actively filters out hard-particle contaminants from hub oil. When you use The Xtractor your parts last longer and you regain the fuel efficiency lost to friction.
Multistage Oil Filter
The Xtractor features a submerged, multistage magnetic filter that captures large debris and fine ferrous particles suspended in hub oil to protect bearings from hard-particle damage. This patent-pending filtration mechanism keeps lubrication oil cleaner, protects against premature wear, and regains fuel efficiency lost to rolling friction.
HexThread® Front Access Cartridge
The Xtractor is equipped with a patent-pending HexThread® front access cartridge which enables easy hub oil service and filter inspection without full disassembly. This feature simplifies routine oil maintenance and makes repairs faster than ever.

What makes The Xtractor unique?
Most hub caps are just passive covers. The Xtractor is a performance-driven component, actively filtering foreign particulates from circulating in hub oil, reducing rolling resistance and safeguarding against particle-induced wear.
What problem does it solve?
Traditional hub caps allow metal & debris to continually circulate through your wheel-end system, causing rolling friction and accelerating component wear. The Xtractor removes contaminants to stop this destructive behavior.
What vehicles is it compatible with?
The Xtractor is engineered for standard Class 7 and 8 trucks and trailers, with fitment options for most standard hub configurations.
Is it field tested and proven?
Of course. The Xtractor has been tested in real-world fleet operations and validated by experienced mechanics and logistics professionals.
Is it easy to install?
Absolutely. The Xtractor fits just like any other heavy-duty hub cap. Bolt, torque, fill.
