Key Features & Benefits
Complete Rear-Wheel Axle Cover Kit
Each set includes one rear axle cover, one removable dome cap, ten Super Spike push-on nut covers and two metal securing washers.
33mm x 4-3/4-Inch Super Spike Nut Covers
Ten included nut covers fit compatible 33mm lug nuts and feature an extended 4-3/4-inch Super Spike profile for a pronounced custom-wheel appearance.
The included nut covers correspond with United Pacific item number 10586B.
Secure Fit on Shorter Wheel Studs
The push-on nut covers are designed to remain secure on compatible shorter wheel studs, including applications with fewer than five exposed threads.
Stud length alone does not confirm compatibility. The lug nuts must still provide the correct 33mm push-on mounting surface.
Removable Dome-Shaped Cap
The centre of the axle cover features a removable dome-shaped cap, providing access beneath the cap without replacing the complete axle cover.
Triple Chrome-Plated Finish
A triple chrome-plating process creates a bright, polished finish that coordinates with other chrome wheel, hub and lug nut accessories.
Lightweight ABS Plastic Construction
The covers are manufactured from high-impact, injection-moulded ABS plastic. This material is lightweight and corrosion resistant while maintaining the defined dome and spike shapes.
Compatible With Several Common Wheel Sizes
The axle cover fits many compatible 20-inch, 22-1/2-inch and 24-1/2-inch commercial-truck wheels.

Installation / Fitment / Technical Details
The dome axle cover installs on a compatible rear wheel using two of the included metal washers as part of the securing arrangement. The ten Super Spike covers push onto the corresponding 33mm lug nuts.
Before ordering or installation, confirm:
- The wheel has ten compatible 33mm lug nuts
- The wheel uses a compatible 11-1/4-inch bolt-circle or centre arrangement
- The wheel diameter is 20, 22-1/2 or 24-1/2 inches
- The rear axle configuration provides adequate clearance
- The two securing locations are compatible with the supplied washers
- The 4-3/4-inch spike covers will not interfere with surrounding components
- Pointed wheel accessories are permitted by applicable regulations and fleet policies
Install each nut cover evenly over the corresponding lug nut and verify that it is completely seated. Inspect the axle cover and nut covers after installation and periodically during regular wheel maintenance.
These covers are decorative accessories. They must not interfere with proper lug-nut inspection, wheel servicing or required torque checks.

The axle cover, removable dome cap and nut covers are manufactured from high-impact, injection-moulded ABS plastic. The lightweight material resists corrosion, while the triple chrome-plated finish provides a bright custom-truck appearance.
