The Fox 014-16-002 is a black polyurethane straight-eye shock bushing, sized at 1.650 in. OD, 0.500 in. ID and 0.710 in. length. It replaces the worn or damaged bushing in a Fox shock eyelet, so the shock keeps a tight, correctly located connection at the mount. Searches like "Fox polyurethane shock bushing 014-16-002," "straight eye shock bushing 1.650 OD," and "Fox shock eyelet bushing replacement" describe exactly what this part does.
A buyer who is tired of play at the eyelet has a clear reason to choose this part. Replacing only the bushing restores tighter, more predictable shock action without buying a new shock, and it is far cheaper than a full rebuild. Because it is sold as a single unit, you can refresh one or both ends of a shock as needed. Confirm the bore and thickness against your eyelet before ordering, since the correct size depends on the shock and mount, and check with the manufacturer if you are unsure.
Replacing this bushing is a press-fit job that calls for a bench vise, a bushing tool or ejector pin with a guide, and a light grease. Owners on user forums describe pressing the old bushing out through the eyelet, cleaning the bore, greasing the new bushing and the eyelet surfaces, and pressing the new one in square until it sits flush. Take the shock off the vehicle and disassemble it as needed before pressing. Inspect the eyelet for damage, and do not force the bushing at an angle.
