XD Series 1079L170 Center Cap Guide: How to Verify the Right Part
If 1079L170 is the number you are trying to replace, you are close—but you are not done.
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.

1079L170 and the other listed identifiers
The current product record tells shoppers to verify 1079L170, E9L-Y29-R4R. 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.
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.
Make the replacement decision in the right order
Put the original wheel center cap beside the live XD Series listing and work from the least ambiguous evidence to the most subjective. Begin with 1079L170, E9L-Y29-R4R. Next compare the rear outline and every visible retention point. Only after those checks agree should you use the photographed finish, logo placement and ordinary cosmetic wear to judge the visual match. This order keeps a convincing face photo from overruling a different mechanical design.
Photographs work best when they answer one question each. Take one straight-on face shot, one straight-on back shot and one side-profile shot. Add a close-up of the complete number. This makes it easier to compare 1079L170 without glare, perspective or a decorative logo hiding the feature that matters.
Checkout check: reopen the live page and verify the finish, quantity and package contents one last time. Saved search results can outlive the offer they describe.
A practical inspection notebook for 1079L170
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 the finish shown in the listing. A neutral, unfiltered image gives the seller better evidence and makes a one-cap replacement easier to compare with the remaining set.
Check center clearance when it is relevant. If an axle end, locking hub or other component projects through the wheel center, include that clearance in the comparison. The supplied listing does not promise an open-end conversion or extra internal room unless it states one. Ask before modifying the new part.
Clean gently for identification. Use a soft cloth to expose molded or printed marks on the old wheel center cap. Aggressive scraping can remove a sticker, flatten shallow lettering or alter the edge you need to compare. The objective is readable evidence, not a showroom finish. Photograph the markings as soon as they become legible.
Interpret wear cautiously. Sun, brake dust, cleaners and road debris can change the apparent the finish shown in the listing 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.
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.
Save the successful match. Once the part has been verified, keep a rear photo, the complete 1079L170 identifier and the product link with your wheel records. That small archive turns the next loss into a direct lookup and preserves details that may be hidden after installation.
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.
A matching logo is only the first check
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.
Build a clean comparison record before you shop
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.
How to verify 1079L170 before ordering
-
Read every identifier. Match
1079L170,E9L-Y29-R4R, 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.
