KMC XD Series M-959 Center Cap Guide: Part Numbers and Ordering
A front photo can make the M-959 cap look easy to identify. The back side and the complete part number are what finish the job.
The current WheelCenterCaps.com record identifies this as new replacement item wheel center cap from KMC XD Series in Black. The listing is the source for those details; anything it does not state stays unclaimed.
Here is the blunt truth: a similar-looking part is not a confirmed match.

Start with the complete M-959 identifier
The current listing uses M-959 as the part number to verify. Match the complete identifier—including letters, suffixes and punctuation—rather than searching only a shortened fragment.
If the number on your original item is different, stop and investigate the difference before ordering. One changed letter or digit can identify another finish, depth, retention design or product family; this record does not establish which difference applies.
The listed finish is Black
The product record describes the finish as Black. That wording matters when you are replacing one item instead of a complete set. “Black” is not specific enough when gloss, matte, satin and mixed-finish parts can look very different beside one another.
Compare the live product image with the surviving parts in neutral daylight. Also compare the logo and any decorative details that are actually visible. Lighting, dust and years of exposure can make the same finish photograph differently.
Mounting style is not confirmed in the supplied listing
The product record does not identify a specific attachment style. We are not going to turn a photo into a claim about clips, tabs, bolts or screws. Compare the back of the original item with every available product image and ask for confirmation if the mounting design is not visible.
How many pieces does the listing describe?
The product record says Sold individually. Quantity language matters: a product photograph may show more than one angle or component without promising that every pictured item is included.
What this product record does not establish
The supplied listing does not state an exact cap diameter, height or depth, the material, a confirmed attachment style or whether mounting hardware is included. Those are reasons to verify—not invitations to guess.
If one of those details decides fitment, compare the original item directly with the live product photos or contact WheelCenterCaps.com before ordering.
What to do when the old cap is missing
Save a small identification record for KMC XD Series M-959: one screenshot of the current title, one clear photo of the original marking and one rear-view photo. Add Sold individually and any wheel or lug note printed in the listing as notes. That record is useful if another cap disappears months later and it prevents a shortened marketplace title from replacing the complete part information.
Attachment language should be read literally. This record supports the back-side retention design shown in the photos; it does not supply dimensions or fastener specifications that are not printed. If the photo does not show the decisive mounting detail, ask for confirmation instead of borrowing a specification from a related part.
Do not mix standards: compare measurements taken from the same points and photos taken from similar angles. Consistent reference points prevent a false mismatch.
Turn the original cap into reliable evidence
Account for photo scale. A tightly cropped thumbnail can make two differently sized parts occupy the same amount of screen space. Look for a stated measurement or ask for one taken from a defined point. Never infer the diameter of this wheel center cap from how large it appears against a white background.
Read the wheel, not just the vehicle. Photograph any wheel-brand, model, size, offset or casting information that is genuinely visible. Those clues can help narrow a catalog, but they do not override a different M-959 marking or back design. The wheel is the application; the vehicle badge is only context.
Manage glare instead of editing it away. Reflective and dark finishes can hide edges in a phone photo. Move the light or the part until the surface is readable, but do not use filters that change Black. A neutral, unfiltered image gives the seller better evidence and makes a one-cap replacement easier to compare with the remaining set.
Map the mounting points. Count the tabs, clips, holes or fastener locations that are actually visible, then note their spacing and orientation. Compare that map with the photographed mounting design in the current photos. A front design can be reused over more than one rear architecture, so the mounting map deserves its own check.
Name every measurement. “Eight inches” is not useful unless both people know whether it means the face, the rear skirt or a mounting circle. Label the start and end points in your photo and keep the ruler in the same plane as the feature. The supplied record should not be supplemented with an unlabeled number from a different listing.
Decide whether one replacement will look intentional. A new Black part may sit beside three weathered originals. That cosmetic difference does not establish bad fitment, but it can affect whether a single or full-set purchase meets your goal. Confirm Sold individually before assuming the listing solves either option.
The cap fits the wheel—not the vehicle badge
A vehicle year, make and model cannot identify an aftermarket wheel center cap by itself. The same truck, SUV or car can wear factory wheels, several aftermarket wheel models or a different wheel on each trim package.
Use vehicle information as background only. The stronger evidence is the complete part number, the wheel itself and a physical comparison of the original cap with the current listing.
The back of the cap can settle the question
Many wrong-cap orders begin with a convincing front view. A logo, outline or finish may look right while the back of the cap uses a different shell profile, retention layout or mounting position. The supplied record does not establish that a similar-looking cap with another part number is interchangeable with this one.
Set the original cap beside the live product photos and compare both sides in the same order. Start with the complete molded or printed number. Then check the face, edge profile and every visible point where the cap meets the wheel. If one photo hides the feature that decides the match, treat that detail as unresolved.
Also account for ordinary wear. Sun exposure, brake dust, cleaners and scratches can change how an older cap looks without changing its identity. Use finish as supporting evidence, but let the complete identifier and physical design carry more weight.
Document the original before making the match
A few clear photos and notes are more useful than trying to remember a part after it has been removed. Clean only enough dirt to reveal the identifier and attachment details; do not grind, scrape or polish away markings. Work in even light and keep the camera square to the item so perspective does not exaggerate its shape.
- Capture the identifier. Photograph the complete number in focus, including any prefix, suffix, dash or space. Write it down exactly as shown.
- Photograph both sides. Take a straight-on face image and a clear rear view. Add close-ups of retention points, holes, tabs or other features that are actually present.
- Record comparison measurements. When a measurement is needed, note where it starts and ends and which tool you used. A number without consistent reference points is easy to misread.
- Save the listing evidence. Compare your notes with the current title, description and photos at checkout. Product offers can change, so confirm quantity and included pieces on the page you are buying from.
If the original item is missing, do not replace it with a guess based on the vehicle alone. Record the wheel brand, any wheel model or casting numbers you can actually see, and clear photos of the mounting area. Send that evidence when asking for help; it gives the seller something specific to evaluate.
A no-guesswork identification checklist
-
Read every identifier. Match
M-959, the SKU where useful and every number visible on the original cap. - Compare the front. Check the outline, logo, finish and any decorative details shown in the live listing.
- Compare the back. Match the shell profile, retention points and mounting locations without assuming a similar face means the same cap.
- Measure consistently. If dimensions are not published, measure the surviving cap and ask the seller to confirm the same points on the replacement.
- Confirm the offer. Verify finish, quantity and included hardware on the current product page before checkout.
Frequently asked questions
Will M-959 fit my vehicle?
Only if the wheel on that vehicle uses the matching center-cap design. Vehicle year, make and model alone are not enough.
Which numbers should I match?
The current record lists M-959 and store SKU CAP M-959 Black. Match the complete identifiers and product design instead of relying on one shortened number.
What finish does the listing identify?
The supplied product record lists Black. Compare the live image with the parts already on the wheel before ordering one replacement.
How does it attach?
The supplied listing does not confirm the attachment style. Compare the original and the product photos or ask for confirmation before ordering.
Is the listing for one piece or a set?
The product record says Sold individually.
Is mounting hardware included?
The supplied record does not establish that. Do not assume screws, bolts, retainers or tools are included unless the live product page explicitly says so.
What are the dimensions?
No exact diameter, height or depth is stated in the supplied record. Measure the original cap consistently and request confirmation rather than borrowing a measurement from another listing.
Shop the correct replacement
The rule is simple: exact number, exact design, exact offer. Do those checks before the box ships.
