A “Series 06 center cap 14” search usually means a replacement center cover for a 14-inch HiSpec or HWT Series 06 trailer wheel. The 14-inch figure describes the wheel size, not the cap’s face diameter. To choose the replacement, match the wheel’s series, part number, finish and mounting arrangement.
For a black-inlay wheel marked 0645545B, two useful seller references are 06-14CAPB and CCS024. For a silver Series 06 wheel, seller item 90098 is a separate lead. These listings have different identifiers and stated coverage; verify your wheel against the particular seller’s listing before ordering.
Series 06 replacement center caps to compare
| Seller and item | Stated wheel fitment | Finish and attachment | Buying detail to confirm |
|---|---|---|---|
| Trailer and Truck Parts: ST-06-14CAPB / 06-14CAPB | HiSpec Series 06, 14-inch wheel 0645545B | Black inlay; cap-only listing | The page does not specify the supplied mounting hardware or the cap’s outer diameter. |
| Recstuff: CCS024 | HiSpec Series 06, 13- and 14-inch wheels; the description names 0635545B and 0645545B | Black inlay; replacement retaining screw included | Match the named wheel part number and confirm the cap dimensions and quantity. |
| Need a Trailer Part: 90098 | Hi-Spec Series 06 Silver Star, 13- and 14-inch, five-lug wheels | Chrome/silver; mounts to the wheel with an included screw, over the dust cap | Confirm the silver wheel style, back profile, clearance and package quantity. |
The 06-14CAPB listing explicitly names wheel 0645545B. Recstuff’s CCS024 listing gives the two wheel part numbers and states that a replacement screw is included. The 90098 silver cap listing describes five-lug Silver Star wheels and the mounting screw. None of these descriptions makes the cap universal for 14-inch wheels.
Identify the wheel before measuring the cap
- Find the wheel’s identity. Look for the manufacturer, series and part number in your wheel paperwork or accessible markings. Photograph the complete wheel face, remaining cap and mounting point. A trailer’s make and year alone may not identify wheels that were changed later.
- Confirm the wheel diameter. Check the wheel marking or documented wheel size. A 14-inch tire/wheel designation does not give you the center-cover diameter.
- Record the finish and spoke pattern. Black inlay and silver/chrome versions can look similar in a small listing photo. Match the whole face and the back of a surviving cap.
- Check the attachment. Determine whether your existing cover is retained by a screw or uses another arrangement. Do not substitute a generic push-through or snap-in cap for a screw-retained cover simply because both are called center caps.
- Compare the seller’s named wheel numbers. An exact wheel-number match is stronger evidence than the same tire size or a similar logo.
For example, CCS024’s stated coverage includes wheel 0645545B, while the same seller’s CCS026 listing is for 16-inch Series 06 wheels and names 0667655B and 0667865HDB. The shared Series 06 name does not make those two caps interchangeable.
Keep these measurements separate
There are several different “diameters” in a wheel-cap search. Record them with labels rather than sending a seller one unexplained number:
- Wheel diameter: the nominal wheel size, such as 14 inches.
- Cap face diameter: the widest outside measurement across the decorative cover. Measure a surviving cap if you have one.
- Wheel pilot opening: the opening at the center of the wheel. This is a separate dimension and does not establish the face diameter of a cover that extends over the wheel face.
- Rear profile and depth: the shape behind the cap and the clearance needed around the hub or dust cap.
- Mounting location: the retaining-screw position and the matching feature on the wheel. Ask for the correct screw specification if yours is missing.
The linked CCS024, 06-14CAPB and 90098 descriptions do not give a complete dimensioned drawing. Obtain the actual outside diameter, rear dimensions and attachment details from the seller if a part-number match is uncertain. Do not copy a dimension from a different center cap with the same wheel-size label.
What to send a parts seller
A concise fitment request saves guesswork: “I have a HiSpec Series 06 wheel marked [wheel part number], with a [black-inlay or silver] finish and [wheel diameter]. My existing cap measures [outside diameter] across the face and uses [attachment]. Will your item [seller part number] fit, and does it include the correct retaining screw?” Attach clear front and rear photos of a remaining cap and a photo of the wheel mounting point.
If the original cap is gone, say so. Have the seller confirm fit from the wheel number and wheel photos instead of estimating the hidden dimensions. If you are buying multiple caps, verify the quantity per package; a photo showing several wheels or several caps does not establish the sale quantity.
Installation checks for a screw-retained cover
Follow the instructions for the confirmed cap and wheel. With the trailer safely parked, compare the replacement’s back profile with the old part and inspect the mounting point. A cracked cover, broken mounting feature or damaged screw thread needs attention before the replacement is fitted.
The correct cover should seat in its intended position without being pulled into shape by the screw. Use the specified retaining hardware and tightening guidance. Do not improvise a longer screw, force a mismatched cap onto the wheel, or drill the wheel to make a cover fit. No generic screw torque is provided here because the cited listings do not establish one.
If wheel removal or access behind the wheel is needed, use the trailer and wheel manufacturer’s service procedure or have a qualified shop handle it. The decorative cap and its small retaining screw are separate from the wheel’s lug nuts and their torque requirements.
Center cover, dust cap and load rating are different things
The silver 90098 listing specifically describes a cover that installs over the dust cap. Replacing that decorative cover is not a substitute for replacing a missing or damaged bearing dust cap. If the part missing is directly on the hub, establish which component is needed before buying a wheel cover.
A center-cover listing also does not establish the trailer’s carrying capacity, wheel capacity or tire pressure. Those depend on the relevant trailer, axle, wheel and tire specifications. Neither “Series 06” nor “14” is a cap load rating.
Frequently asked questions
Does a Series 06 center cap fit any 14-inch trailer wheel?
No. Match the exact wheel series and part number, finish, rear profile and attachment. Wheel diameter alone is insufficient.
Is 06-14CAPB the same seller item as CCS024?
They are different listing identifiers. Both cited descriptions name wheel 0645545B, but the CCS024 page also lists a 13-inch wheel and includes a replacement screw. Confirm the particular seller’s part and package rather than assuming every detail is identical.
Does the replacement come with a screw?
The CCS024 and silver 90098 pages explicitly say the mounting screw is included. The cited 06-14CAPB page does not establish that detail, so confirm it before ordering.
How wide is a “14-inch” center cap?
The 14-inch description refers to the wheel. It is not the outside diameter of the cap. Measure a remaining cover or obtain the dimensions for the exact seller item.
Can I use a 15- or 16-inch Series 06 cap instead?
Do not assume so. Sellers list separate items for different Series 06 wheel sizes and part numbers. Use a replacement explicitly confirmed for your wheel.
