US Mag Wheel Cap

US Mag Wheel Caps: The Finishing Touch from a Custom Wheel Legend

When you invest in a set of US Mag wheels, every detail matters — right down to the center cap. US Mag's wheel caps are engineered and styled as an integral part of the wheel design, not an afterthought. Whether you're restoring a vintage muscle car or building a show-stopping street truck, the right wheel cap completes the look and protects the hub from road grime and moisture.

Wheel caps serve double duty: they shield lug nuts, hub hardware, and bearing areas from the elements while projecting the brand identity that makes a set of custom wheels instantly recognizable. With US Mag, that identity runs deep. US Mag's roots trace back to the mid-1960s, when American racing legend Parnelli Jones and his childhood friend Art Hale Sr. started up a wheel company called US Mags, and in early 2010, Art Hale Jr. reacquired the US Mags brand and re-introduced the original five-spoke "Standard" and kidney bean "Indy" design that originally fueled the custom wheel market. That heritage shows in every cap.

US Mag Wheel Cap Product Lines

US Mag offers a well-rounded lineup of wheel caps designed to match their specific wheel series. Cap styles include the O-Ring Knock-off Cap, Spinner Bolt-On Knock-Off Cap, Spinner Thread-On Knock-Off Cap, and the Precision Series Center Cap in Short, Mid, and Tall profiles. This range means you can find the right cap profile to complement the depth and dish of your particular US Mag wheel fitment.

• Precision Series Center Caps – Available in short, mid, and tall heights to accommodate different wheel backspacing and hub depths, these caps deliver a clean, polished presentation across US Mag's modern wheel lineup.
• Spinner Knock-Off Caps – Made from aluminum with a fully polished finish, spinner knock-off caps install from the front of the wheel and feature a set-screw retention system, nodding to classic wing-nut knock-off style associated with vintage racing and hot rod culture.
• Snap-In Center Caps – Flat, snap-on aluminum caps in a chrome finish bearing the US Mags logo offer a simple, low-profile solution ideal for wheel series like the Rambler U111.

Fitment & Finish Options

US Mag wheel caps are designed to be wheel-series specific, ensuring a proper, rattle-free fit. Finish options span polished aluminum, chrome, gloss black, and gray, so it's possible to match or tastefully contrast the finish of your wheels. Whether you drive a muscle car, classic, or modern street truck, US Mag can customize your wheels — and caps — to truly reflect your vision, with more styles, fitments, and finish options than most competitors.

Because US Mag caps are sold per wheel series rather than universally, they deliver the precise sizing and correct logo presentation for each model. Getting an exact OEM-matched replacement is straightforward when you shop by wheel series name or part number.

Why Choose US Mag Wheel Caps?

US Mag is known for being one of the original manufacturers of the 20-inch passenger vehicle rim and for their signature five-spoke Standard and kidney bean Indy wheels — and their wheel caps carry that same iconic styling. Choosing a genuine US Mag wheel cap ensures that the finishing detail on your custom build matches the craftsmanship of the wheel itself, preserving both aesthetics and long-term resale value.
