5.1in Open Cap

The Gorilla 5.1in Open Cap (HC212A) is a universal steel wheel center cap designed to fit vehicles with 5.100-inch outer diameter hub openings. This open-end design accommodates the full range of brake hardware and suspension components without interference, making it an essential replacement or upgrade component for fleet maintenance, off-road recovery operations, and tactical vehicle builds where unobstructed wheel access is required during field operations.

Manufactured from steel with a chrome finish, the cap measures 4.40 inches in height and maintains a 5.100-inch outer diameter specification for precise hub fitment. The open-cap configuration eliminates full-face coverage, preserving access to lug nuts and brake components without removal—a critical consideration for rapid tire service in austere environments. The chrome plating provides corrosion resistance in salt-air and high-moisture operational theaters, extending service life across diverse climates and conditions. Total weight of 0.43 lbs per cap minimizes rotational mass impact on wheel balance and vehicle dynamics.

This cap serves operators, fleet managers, and vehicle technicians who require standardized, reliable hub protection without compromising field-serviceable access. It is equally suited to civilian fleet maintenance, off-road expedition vehicles, tactical training facilities, and any application where a universal 5.1-inch center cap must accommodate variable brake and suspension configurations. The open-end design is preferred in high-duty-cycle environments where rapid wheel changes, brake inspections, and maintenance operations are routine.

Gorilla center caps are standard replacement and upgrade components across commercial fleet, emergency response, and tactical vehicle communities. The universal fitment and open-cap design align with industry standards for vehicles requiring unrestricted hub access. Sold as a single cap; quantity discounts apply for fleet or multi-vehicle applications.
