RBP Wheels Center Cap Buying Guide

RBP (Rolling Big Power) is a well-known name in the truck and off-road wheel market, recognized for their aggressive designs and bold finishes. Their center caps come in both chrome and matte black, and finding the right replacement is straightforward once you understand their part numbering system.

RBP Cap Characteristics

RBP caps use a consistent part number format starting with "6Q052090F" followed by a suffix that indicates the finish and lug configuration. This makes it relatively easy to identify the right cap if you know your finish preference:

  • 6Q052090F-16 / 6Q052090F-6 — Chrome finish caps, suitable for chrome or polished RBP wheel models.
  • 6Q052090F-2 — Matte black finish cap.
  • 6Q052090F-5 — Matte black finish cap, alternate configuration.
  • 6Q052090F-6 — Available in both chrome and matte black variants — verify finish before ordering.

Pro tip: The suffix number on RBP caps often indicates the finish. When in doubt, order by finish (chrome vs. matte black) rather than suffix number, and verify the bore size matches your wheel.

How to Find the Right RBP Cap

  1. Identify your RBP wheel model — RBP model names include Glock, Assassin, and others. Check the back of the wheel or your purchase receipt.
  2. Choose your finish — Chrome or matte black. This is the primary differentiator in the RBP cap lineup.
  3. Measure the bore — Measure the center bore opening in millimeters if the part number is unavailable.
  4. Verify the retention style — RBP caps use a snap-in design. Check that the retention ring groove in your wheel bore is intact before ordering.

Chrome vs. Matte Black RBP Caps

RBP offers both finishes across their lineup. Chrome caps suit builds with polished or chrome accents, while matte black is the go-to for blacked-out or two-tone truck builds. If you're replacing a single cap, match the existing finish exactly — chrome and matte black look very different side by side.
