Mayhem Wheel Fitment
This cap is intended for specific Mayhem wheels requiring C108303MB03. Use the following wheel model names to help identify your application, then confirm the complete center cap part number:
- Mayhem Voyager: Style 8303
- Mayhem Delta: Style 8304

Shopping for a 6x135 or 6x5.5 Mayhem Center Cap?
If you are replacing a cap on aftermarket Mayhem wheels installed on your Ford F-150, Chevrolet Silverado, GMC Sierra, Toyota Tacoma or another truck or SUV, match the installed wheel's center cap rather than choosing by vehicle name alone.
A matching vehicle or bolt pattern does not confirm center cap fitment. Your wheel must use the C108303MB03 cap with matching dimensions and rear attachment features. This is not a replacement for factory wheel caps.
How to Confirm Your Replacement Cap
- Remove an existing center cap and locate the part number on the back.
- Match the complete number C108303MB03.
- Compare the diameter, rear attachment design, retaining features and overall shape.
- Compare the matte black finish and front appearance with the product photos.
Do not assume that other C108303MB-series caps are interchangeable. The complete part number and physical design must match your application.
Restore Your Wheel's Finished Appearance
A missing or damaged center cap can leave an otherwise complete wheel looking unfinished. Replace the matching cap to restore the center appearance of your Mayhem wheel without purchasing an entire replacement wheel.
