Impact Off-Road SD02-SG Center Cap Guide: Part Numbers and Ordering
A front photo can make the SD02-SG 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 Impact Off-Road in Gloss 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.

SD02-SG and the other listed identifiers
The current product record tells shoppers to verify SD02-SG, F20P424A-6, SD02. 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 Gloss Black
The product record describes the finish as Gloss 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 original part is still available
Do not try to remember the old part from across the garage. Place it on a clean surface, open the current product page and compare one feature at a time. Check SD02-SG, F20P424A-6, SD02, then the edge silhouette, center rise, back shell and the back-side retention design shown in the photos. Finish with color and face details. A written sequence is slower by a minute and faster than a return shipment.
A mismatch is useful information. A different suffix, missing hole, altered tab layout or noticeably different rear depth is a reason to pause, even when the front looks excellent. Do not average conflicting evidence into a “probably.” Resolve the conflict or choose another listing.
Final rule: allow appearance to confirm an already-sound match, not rescue a conflict in the part number or retention design.
Six product-specific checks worth recording
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.
Depth needs a reference surface. If clearance matters, photograph the original beside a straightedge and state whether height was measured from the face, the mounting surface or the deepest rear point. Different reference points can produce different numbers for the same wheel center cap. Do not call them a conflict until the method is the same.
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.
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.
Interpret wear cautiously. Sun, brake dust, cleaners and road debris can change the apparent Gloss 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.
Save the successful match. Once the part has been verified, keep a rear photo, the complete SD02-SG 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.
Why a front-face match can still be wrong
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
SD02-SG,F20P424A-6,SD02, 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 SD02-SG 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 SD02-SG, F20P424A-6, SD02 and store SKU SD02-SG F20P424A-6 SD02 Gloss. 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 Gloss 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.
