Protect your trailer wheel bearings from road grime and simplify routine axle maintenance. Designed to fit standard 5,200 lb to 6,000 lb trailer axles with 6-bolt hub assemblies, this 2.440-inch outer diameter grease cap features a drive-in steel body with a removable center rubber plug. Engineered specifically for E-Z Lube® spindle systems, it allows you to easily access the spindle zerk fitting to pump fresh grease into the bearing cavity without removing the entire dust cap.
