Benefits you can expect

Longer Lasting Parts

A hubcap that's built better and does more to safeguard your bearings and seals.

Lower Cost of Operation

Reduces friction and wear, better preserving fuel economy and critical axle-parts life.

FASTER, EASIER SERVICE

A hubcap that can be serviced in minutes, rather than uninstalled or wholly replaced.

Durability in Tough Conditions

Forget thin-walled parts that crack and fail, Xtractor hub caps are tested to MIL-STD 810F for extreme-condition durability.

Xtractor vs. Other Hub Caps

Filtration vs. Containment

The Xtractor actively improves wheel-end performance while other hubcaps are simply passive covers.

Serviceable vs. Disposable

Designed to be opened, maintained, and put back into service, not thrown away and outright replaced.

ROI vs. Expense

Generates measurable returns through extended parts life and improved fuel efficiency. Others are just an expense.
