Updated June 25, 2026
The Pacer 102HM is a push-thru style wheel center cap designed for aftermarket custom wheels with a 4.25-inch center bore. Manufactured by Pacer, a well-known brand in the custom wheel industry, these caps are made from steel and are available in chrome or black finishes. They install from the back of the wheel, providing a clean, flush appearance that covers the hub and lug nuts. The 102HM is a common replacement or upgrade cap for a wide range of older and modern custom wheels.

Design and Fitment
The Pacer 102HM cap features a 4.25-inch diameter bore fitment, with a total back flange measurement of 4.5 inches and a height of approximately 4.2 inches. The cap is designed to be pushed through the wheel from the rear, securing by friction against the bore. It is important to verify that the wheel's center bore diameter matches 4.25 inches and that the cap's part number (102HM) is cast into the back of the original cap to ensure compatibility. These caps are commonly used on Pacer custom wheels and many other aftermarket rims from the 1970s through current production.
Available Finishes and Configurations
The 102HM is offered in two primary finishes: chrome (part number 102HM) and black (part number 102HM-BK). Both are steel with a durable coating. Additionally, some listings include a combination of open-end and closed-end caps, where the open-end cap exposes the lug nuts and the closed-end cap covers them entirely. Buyers should confirm whether they need open, closed, or a mix depending on their wheel design and personal preference.
Installation Notes
Installation is straightforward: the cap is inserted from the back side of the wheel and pushed forward until it seats firmly in the bore. No special tools are required, but care should be taken to avoid scratching the finish. The cap is held in place by tension; if the fit is loose, the cap may vibrate or fall out. Conversely, if the bore is too tight, the cap may be difficult to install or remove. Always verify that the cap's part number matches the original before purchasing, as slight variations exist between different Pacer cap models.
