Semi-Truck Axle Covers
Compare front and rear axle covers, matching combo kits, high hats and replacement caps for your truck’s wheel setup. Explore dome, pointed, moon and other profiles in chrome-finish and stainless steel options.
Match the axle position, wheel type, lug nut size and mounting requirements before ordering. Check the selected listing for included nut covers, rings and caps—replacement parts are not complete axle-cover kits.
How to Choose Axle Covers
Start with your existing wheel and hub dimensions, then choose the profile and finish. Covers that look similar can use different mounting arrangements or fit different wheel applications.
Front or Rear Application
Choose a cover listed for the axle position you are fitting. Compare hub clearance and overall dimensions, especially when selecting tall rear covers or pointed profiles. Do not assume front and rear covers are interchangeable.
Wheel and Nut Fitment
Check wheel diameter, bolt circle where specified, steel or aluminum wheel compatibility and lug nut size. Some listings offer separate 33mm and 1-1/2-inch configurations; select the variation that matches your hardware.
Mounting and Clearance
Confirm whether the assembly uses push-on or thread-on nut covers and follow its installation requirements. Thread-on designs need the specified exposed thread length. Check clearance around the hub, wheel and nearby accessories.
Complete Kit or Replacement Part
Review the included components before ordering. A combo kit, axle-cover kit, high hat and cap-only replacement are different purchases. Match replacement parts to the specified cover model or part number.
Axle Cover FAQs
How do I know which axle cover will fit my truck?
Match the front or rear application, wheel size, wheel type, lug nut size, bolt circle where specified and hub clearance. Check the exact product's mounting requirements and selected variation. Truck make and model alone do not establish axle-cover fitment.
Are front and rear axle covers interchangeable?
Do not assume they are. Front and rear listings are designed for different hub arrangements and may have different dimensions or mounting components. Choose the application stated in the product description.
What is the difference between push-on and thread-on axle-cover kits?
These descriptions refer to the nut-cover mounting style used by the listed kit. Push-on and thread-on versions require compatible hardware. For thread-on kits, check the specified exposed thread length rather than using a requirement from a different cover.
Will an axle cover fit both steel and aluminum wheels?
Only when the selected product or variation lists that compatibility. Some kits have separate steel, aluminum and steel/aluminum options, with different lug-size requirements. Confirm both wheel type and nut size before selecting an option.
Do axle-cover kits include lug nut covers?
Some do, but contents vary. Read the included-components list for the selected kit and quantity. A high-hat-only or cap-only listing should not be treated as a complete assembly, and nut covers may need to be purchased separately.
Can I replace just the center cap or high hat?
Replacement components are available for certain assemblies. Match the existing cover's model or part number. For example, the Single Hub Design Rear Axle Cover Cap Only is specified for United Pacific item 10272; it is not a universal replacement cap.
Are chrome axle covers made from metal?
Not always. This category includes chrome plastic options as well as polished stainless steel products. Confirm the material in the listing rather than relying on a chrome appearance. Check the care instructions supplied with the chosen product.
