You lose one center cap off an XD wheel, and suddenly your whole truck looks unfinished. The trap is that XD Series wheels share a look but not a fit — caps are keyed to a specific wheel model and lug pattern, so the wrong one snaps in loose or never seats at all. The fix is simple: match the part number stamped on the back of your old cap to the number in the listing title or OEM equivalent field. This guide covers seven caps that are actually listed for XD Series fitment, sorted by what each one is genuinely best at.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Every pick below is a genuine XD Series replacement, from short 8-lug chrome caps to matte black Rockstar 2 pieces, and the quick comparison table lines up the three specs that actually decide fit. Read on for the seven strongest options for your xd series center cap replacement, ranked by fit, finish, and real owner experience.
Top Picks
How To Choose The Best XD Series Center Cap
A center cap is the small disc that covers the hole in the middle of your wheel, hiding the hub and finishing the look. Buy the wrong one and it will either fall out on the first rough road or sit proud of the rim and look off. Four things decide whether it fits: the part number, the lug pattern (the arrangement of the wheel nuts), the mounting style, and the finish.
Start with the part number on the back of the cap
Flip your old cap over and read the number molded or stamped into the back. That number — something like 464K131-2 or SC-198 — is the only reliable way to know which wheel it came from. Listings often show a generic photo, so the part number in the title and the OEM equivalent number in the specs are what you trust. If the number does not match, do not buy, no matter how close the picture looks.
Match the lug pattern to your wheel
The lug pattern is the bolt spacing on your wheel, written as two numbers like 5/6 x 5.5 or 6 x 139.7. A cap built for one pattern can look identical to another and still not clip in properly. Some caps cover all bolt patterns of a specific wheel family, which is worth knowing if you are unsure of your exact pattern.
Snap-on, spoke-clip, bolt-on, or screw-on
Snap-on caps press into the wheel opening and hold by friction or small tabs. Spoke-clip caps grip the spokes. Bolt-on and screw-on caps fasten with hardware, and those screws are sometimes included and sometimes not — check before you order. Snap-on is the quickest to fit but is the style most likely to work loose over time, so treat any plastic retaining tabs gently.
Does the cap come with a lock ring?
A lock ring is the metal ring that seats the cap and holds it tight against the wheel. Some caps ship with the ring included and some are the cap alone. If your wheel uses a ring and the listing does not include one, you will be reusing your old ring or ordering it separately.

Detailed Reviews
1. Wheel Pros XD XDS Cap XD786/XD795 Chrome
Our pick — 4.5+★ from 600+ verified ratings; the strongest balance of quality and price.
The short chrome 8-lug cap that drops straight into the XD786 and XD795 wheels.
If you drive an 8-lug Chevy, Ford, or Dodge with XD786 or XD795 wheels, this is the cap that fits most of them — the listing covers most 8-lug Chevy, Ford, and Dodge applications. It ships with the lock ring included, so you are not hunting down the retaining ring separately before you can fit the wheel back up. The part number on the back reads 464K131-2 S604-17, which is the number to match against your old cap.
Chrome is the finish here, and that is a deliberate look rather than a subtle one. It is a snap-on installation, so fitting is a press-and-seat job rather than a bolt-up. Weight sits at 4 ounces, and against the XD XDS 464K106 at 3.2 ounces this one is the heavier of the two sibling caps — nothing dramatic in the hand, but slightly more substantial. Owners who rate it highest are replacing a cracked or missing 464K131-2 on the same XD786 or XD795 wheel and want the chrome finish to match the other three.
Here is the honest catch, and it is the one that matters most with any snap-on cap: the retaining tabs do the whole job, and plastic tabs are the weak point. The fit itself is what wins people over, and the value is solid for a single chrome cap. But ease of installation splits down the middle in owner feedback, and a few report the cap letting go. Seat it firmly and treat the tabs with care when you remove a wheel.
What earns its keep
- Lock ring included, so the cap is ready to seat without extra parts
- Chrome finish matches factory-style 8-lug XD look
- Covers most 8-lug Chevy, Ford, and Dodge fitments
- Snap-on install keeps the job quick
Where it asks for care
- Retaining tabs are the weak point and can break if handled roughly
- Snap-on hold can work loose on rough roads
- Sold as a single cap, so replacing all four means buying four
Reach for this if: you run 8-lug XD786 or XD795 wheels and want the cap that fits the widest spread of those trucks.
Think twice if: you are hard on your wheels off-road — the snap-on tabs are the part that gives first.
2. XD XDS Cap XD786/XD795 Chrome 5/6X5.5 108CB – 464K106
The 5/6 x 5.5 pattern cap that owners say still looks fresh after dirt and snow.
The build quality is the headline here, and it is the thing buyers talk about above everything else. It is a metal cap, not a plastic one, and it fits the XD786 and XD795 wheels with the 5/6 x 5.5 lug pattern. That five-and-six-bolt spacing covers a big share of half-ton trucks, so if you are not sure whether your wheel is 5-lug or 6-lug on a 5.5 spacing, this is designed to work either way.
At 3.2 ounces it is the lighter of the two XD786/XD795 chrome caps, and against the 464K131-2 at 4 ounces that weight difference is the clearest way to tell the two apart in hand. Finish is a silver exterior, and the appearance holds up — buyers report the cap still looking new even after exposure to dirt and snow. It is a snap-on style with spoke-clip retention, meaning it grips the spokes as well as seating into the opening.
What it is not is a lock-ring kit — check the listing against your old cap’s hardware before you assume everything you need is in the box. As a factory-style replacement for a 5/6 x 5.5 wheel, though, it is the straightforward choice, and the value is the reason it sits near the top of this list.
Where it shines: metal construction and a lug pattern that fits both 5-lug and 6-lug 5.5 wheels, with an appearance that survives winter grime.
Worth checking first: confirm your wheel’s part number and if you need a separate lock ring (the ring that secures the cap) — this is a cap, not a hardware kit.
Best fit for: half-ton XD786/XD795 owners on the 5/6 x 5.5 pattern who want a metal cap that keeps its look.
Look elsewhere if: you are replacing an 8-lug setup — that is a different cap entirely.
3. KMC XD Series 796 797 798 Matte Flat Black 6 Lug Center Cap
Matte black for the 796, 797, and 798 wheels, built to bolt on and stay put.
If you have sprayed your XD 796, 797, or 798 wheels satin and the shiny chrome cap now looks out of place, this is the piece that fixes it. The finish is matte flat black, made from ABS — that is acrylonitrile butadiene styrene, a tough molded plastic that takes a matte texture well. The lug pattern is 6 x 139.7, also written 6 x 5.5, which lines up with a common six-lug truck spacing.
The mounting style is the part that separates it from the snap-on caps above: this one is bolt-on. That is a more secure hold than friction tabs, and it means less chance of the cap walking loose. Fit is what gets praised — owners mention it dropping onto 18-inch wheels nicely.
The trade-off to know about is appearance matching. Feedback splits on how exactly the black matches the wheel — some say it is spot on, others find it does not align precisely with the original. That is a color-and-tone issue rather than a fit one, and it is the kind of thing that shows up more under bright light than in a photo. If you are picky about an exact black, look at your wheel in daylight first.
The deciding factor: bolt-on mounting and a 6 x 5.5 pattern for the 796/797/798 family, in a matte finish that suits darkened wheels.
The honest caveat: black-on-black matching can read slightly off against some wheel finishes — fit is solid, tone is the wildcard.
Made for: six-lug XD 796, 797, or 798 wheels that need a matte black cap with a bolted hold.
Second-guess it if: you need an exact factory-black tone match and cannot see the wheel and cap side by side first.
4. XD Series by KMC Wheels 8 Lug Matte Flat Black Center Cap
The aluminum 8-lug cap aimed squarely at heavy-duty diesel rims.
This is the cap you look at when your truck is an 8-lug diesel and the wheel is one of the 441, 796, 797, 798, 800, or 801 models. It is made of aluminum rather than plastic, which matters because aluminum holds its shape and finish over repeated wheel swaps. The mounting is screw-on — the maker notes the screws are part of the install, and it is a more involved fit than a press-in cap. Finish is a matte flat black.
What buyers respond to is the quality and the fact that it works as a direct replacement for 8-lug diesel rims. Customers note it seats flush against the 441, 796, 797, 798, 800, and 801 wheel faces, which is the whole game with a screw-on center cap. The 8-lug size is spelled out in the name and the specs, so there is little guesswork about which wheel family it belongs to.
The manufacturer is direct about one thing: the buyer is responsible for confirming the part number fits the application. That is not a flaw — it is a reminder to check 309B170-8H against your old cap before ordering. Cross-check 309B170-8H against your old cap and this aluminum screw-on cap is a direct replacement for an 8-lug diesel rim.
For the diesel owner: 8-lug trucks on XD 441, 796, 797, 798, 800, or 801 wheels that want an aluminum screw-on cap.
Not for you if: you have a lighter half-ton wheel or want a quick snap-in fit — this one screws on and is built for the heavy-duty bolt pattern.
5. XD SERIES KMC 811 Rockstar 2 Center Cap
One cap for every Rockstar 2 bolt pattern — the specific-fit headache removed.
Most center caps force you to confirm your exact lug pattern before you order. This one sidesteps that entirely: it fits all bolt patterns of Rockstar 2 wheels, states the listing plainly. If you have the XD 811 Rockstar 2 wheel and you are tired of playing pattern detective, that single line is the reason to shortlist it. The part number on the back is SC-198 or SC-190, so match against whichever one your old cap shows.
Finish is a matte black exterior, with a gloss black element in the mix for contrast. Screws are included, and the mounting is screw-on, so the hold is secured by hardware rather than friction tabs. Weight and build are metal, which is a step up from molded plastic caps for longevity.
The money question with a universal-fit cap is always whether “fits all” really means it. Here the claim is scoped to a specific wheel family, the 811 Rockstar 2, so it is not a generic universal promise — it is a universal-within-one-wheel design. For an XD 811 Rockstar 2 owner, skipping the bolt-pattern check entirely is the whole appeal.
The standout: bolt-pattern coverage of every Rockstar 2 variant, plus screws in the box for a secure screw-on fit.
Confirm before you buy: this is for the 811 Rockstar 2 wheel specifically — it will not suit other XD families just because the name says XD.
Ideal for: XD 811 Rockstar 2 owners who want a matte black cap without verifying which bolt pattern they have.
Wrong pick for: any non-Rockstar 2 wheel — the broad fit applies only inside that one family.
6. KMC XD Series Monster II 2 Cap M-959 Black Wheel Center Cap
Alloy-steel cap for Monster II wheels, with the screws already included.
The material is the standout: this cap is alloy steel, not plastic, which puts it in a sturdier class than the molded ABS caps on this list. It fits the XD Monster II 2 wheel, and the part number on the back is CAP M-959 — that is your match reference. Screws are included, and the mounting is screw-on, so the install is hardware-secured rather than pushed in and hoped for.
Finish is black, and it is a shallow piece — less than 1 inch deep, roughly a quarter to half an inch in practice. That low profile matters: a cap that does not stand proud looks integrated rather than added on. It lists as a universal fit, which here means it is designed to work across the Monster II applications rather than a single lug pattern. The color combines black with a silver element for contrast.
One thing to read carefully: inserts are not included. If your wheel’s center calls for an insert behind the cap, you will be sourcing that piece separately. With that checked, this is a strong, steel-built replacement for a Monster II wheel that needs its center finished properly.
Reasons it holds up
- Alloy steel construction for a sturdier build than plastic caps
- Screws included for a secure screw-on fit
- Low profile under 1 inch deep sits close to the wheel face
- Part number CAP M-959 makes matching straightforward
Before you commit
- Inserts are not included with the cap
- Universal-fit listing means you still confirm your wheel model
- Sold as a single cap
Worth grabbing if: you have Monster II wheels and want a steel cap that sits flush and comes with its screws.
Check first: whether your wheel needs an insert, since this cap does not include one.
Know the Specs
Part Number and OEM Equivalent
The part number is the code on the back of the cap that ties it to one exact wheel. Listings show it in the title and repeat it as the OEM equivalent number, which is the manufacturer’s original reference for that piece. This is the single most reliable match point — a photo can look identical while the part number is for a different wheel. Always cross-check your old cap’s number against both before buying.
Lug Pattern
The lug pattern is the bolt spacing on your wheel, written as two numbers such as 5/6 x 5.5 or 6 x 139.7. A cap sized for one pattern may look the same as another but will not clip in properly. Some caps here cover a range, like the 5/6 x 5.5 pattern that handles both five-bolt and six-bolt 5.5 wheels, while others are locked to a single family such as the 8-lug diesel fitment.
Mounting Type
Snap-on, spoke-clip, bolt-on, and screw-on describe how the cap is held in place. Snap-on presses in and relies on friction or small tabs — quick to fit but the style most likely to work loose. Bolt-on and screw-on use hardware, which is more secure but requires the screws to be present. Spoke-clip grips the wheel spokes. Match the mounting style to how much rough driving your truck sees.
Finish and Material
Chrome gives a bright factory-style look; matte flat black suits darkened wheels and hides brake dust better. Material matters for longevity: ABS is a tough molded plastic, aluminum holds shape over repeated swaps, and alloy steel is the sturdiest of the group. Plastic caps are lighter but their retaining tabs are the part that gives first, so treat them gently when removing a wheel.

If you run the 5/6 x 5.5 pattern (the bolt spacing on your wheel) and want a metal cap that survives winter grime, reach for the XD XDS 464K106. And if you have Rockstar 2 wheels and want to skip the bolt-pattern hunt entirely, the XD KMC 811 Rockstar 2 SC-198 fits every pattern of that wheel. Confirm the part number off your old cap before you order and the swap is a five-minute job that finishes your truck properly.
