ATX Series Center Cap Buying Guide

ATX Series wheels are produced under the American Racing umbrella and are built specifically for off-road and truck applications. Known for their rugged styling and Teflon-coated finishes, ATX wheels are a popular choice for serious off-road builds — but finding the right replacement center cap requires knowing a few key details. Here's everything you need.

ATX Series Cap Characteristics

ATX caps are closely related to American Racing caps since they share the same parent brand. Many ATX caps use a Teflon coating for durability in off-road conditions, making them more resistant to chipping and corrosion than standard painted caps. Key part numbers include:

  • 1307106017 / 1342106017 — Black Teflon-coated caps used across multiple ATX models. One of the most common ATX replacements.
  • X1834147-9 — Cross-reference number for the 1342106017 cap.
  • SC157B / SC-157 / S808-07 — Black cap for the ATX AX181 Artillery series.

Pro tip: ATX caps are often sold in 4-packs, which is useful if you're replacing all caps on a set of wheels at once. Check if a multi-pack is available before ordering singles.

How to Find the Right ATX Cap

  1. Identify your ATX wheel model — ATX model numbers start with "AX" (e.g., AX181 Artillery). Check the back of the wheel or your purchase receipt.
  2. Match the finish — Most ATX caps are black (Teflon-coated or painted). Verify whether your wheel uses a matte or gloss black cap.
  3. Cross-reference with American Racing — Because ATX is under the American Racing brand, some AR caps are compatible with ATX wheels. Check both catalogs if your specific cap is unavailable.
  4. Measure the bore — If the part number is unavailable, measure the center bore diameter in millimeters.

ATX vs. American Racing Caps: Are They Interchangeable?

Sometimes, yes. ATX and American Racing share manufacturing and some cap designs. The 1342106017 cap, for example, appears in both catalogs. However, not all caps cross over — always verify the bore size and retention style before assuming compatibility.
