Overview
The 4 Wheel Parts Factory S-Series 5 on 5.5 center cap in gloss black (part number 4WP801855502) is a push-thru cap for 5×5.5 bolt pattern wheels.
The S-Series is a 4 Wheel Parts wheel line that the brand describes as mesh style street wheels with milled accents, aimed at truck and Jeep owners moving up to larger tires. A closed cap covers the center of the wheel, which gives a finished look over the hub.
Key features
- Push-thru style cap
- Closed design covers the hub center
- Gloss black finish
- Fits a 5×5.5 bolt pattern
- Matches the S-Series line, which 4 Wheel Parts describes with a 3D mesh design
Center caps and hub fit
A push-thru center cap is held in the wheel’s center bore by friction and a snug fit, not by screws. Before fitting one, check that the bore is clean and free of paint or corrosion, since a rough bore can keep the cap from seating flat against the wheel face.
Gloss black finishes show scratches and water spots more than satin or matte finishes, so a soft microfiber cloth and a pH-neutral wheel cleaner keep them looking sharp. Avoid abrasive pads, which can leave fine marks in the gloss.
Caps can work loose after heavy trail use or repeated wheel removal. Look at the cap during tire rotations and press it back in if it sits proud of the wheel face. A cap that rattles or drops out is worn or undersized and should be replaced.
- Clean the bore before pressing the cap in
- Check the cap during tire rotations
- Use a soft cloth on glossy finishes
- Replace a cap that no longer seats firmly
