Pro Comp 603116500-CAP Center Cap Identification Guide
Shopping for a 603116500-CAP center cap is not a “looks close enough” decision.
This guide uses only the facts present in the current product record. It will tell you what the listing establishes, what it leaves open and what to compare before checkout.
Here is the blunt truth: a similar-looking part is not a confirmed match.

603116500-CAP and the other listed identifiers
The current product record tells shoppers to verify 603116500-CAP, 603165500. Do not silently drop a suffix or choose only the shortest number because it is easier to type. Record every identifier shown on your original item, then compare the complete set with the live listing.
These numbers appear together in this listing. That does not prove that every item carrying only one of them is universally interchangeable. The physical design still has to match.
The listed finish is Matte Black
The product record describes the finish as Matte 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.
Use a side-by-side match, not a memory test
If one original cap survives, it is your best evidence. Clean only enough grime to read the markings, photograph 603116500-CAP, 603165500 and keep the cap nearby while reviewing the listing. Compare the face and back under similar light. Do not sand, reshape or remove clips merely to make a questionable replacement appear closer.
One correct replacement is the goal, not the largest list of possible interchanges. Unless the current record explicitly identifies another code, treat outside aliases as leads that still require a physical match. This keeps an unverified marketplace cross-reference from becoming a fitment claim.
Stop condition: if the complete identifier or the rear design disagrees, do not install the part. Contact Pro Comp support or the seller with the photos you collected.
Turn the original cap into reliable evidence
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.
Interpret wear cautiously. Sun, brake dust, cleaners and road debris can change the apparent Matte Black and soften printed details. Wear can explain a cosmetic difference, but it cannot explain a different number, missing mounting point or incompatible rear shell. Separate age-related appearance from structural identity.
Compare sheen, not only color. The record uses Matte Black. Look at how light rolls across the surface and how the logo or accents contrast with it. Dust and aging can dull an original, so finish is best used after the identifier and mechanical design agree—not as a shortcut around them.
Separate the cap from the package. The page identifies the offer as Sold individually. Photos may show hardware, multiple angles or a complete wheel for context without defining everything in the box. Read the written package statement at checkout and ask what is included when the description is silent.
Make support easy to answer. Send one message containing 603116500-CAP, 603165500, 603116500-CAP 603165500 MB, a full wheel photo, front and rear images of the original, and the one measurement that decides your concern. A compact evidence set produces a more useful answer than several messages that reveal the part details one at a time.
Label the removed part. If the old wheel center cap will be off the wheel for several days, store it with its fasteners or retainers in a labeled bag. Add the wheel position and 603116500-CAP. This prevents a later comparison from mixing hardware between wheels or losing the only component that proves the original layout.
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.
The five-check ordering routine
-
Read every identifier. Match
603116500-CAP,603165500, 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.
