The Turbo Lube oil bath lubricating system rotates individual roller bearings over four times through oil for each wheel revolution. This helps your hub and bearings stay cool, reducing wear and friction. This system increases tow vehicle mileage.

The unique see through threaded oil cap assures a leak proof seal, and let's you know if your bearings have adequate lubrication.

NOTE: Fits all wheels with a center hole of 2.90" or larger, may not fit all 8" to 13" wheels.
