Note: One of the weak points of XK-120 steering is the two pin and bush assemblies that connect the steering box and idler arms to the steering linkage. Rubber is bonded to an inner pin and an outer tapered sleeve. As the linkage moves, the pin rotates relative to the stationary sleeve and the rubber stretches. While this does provide some self-centering capability to the steering, it’s also a rather artificial resistance. In addition, the rubber commonly tears, resulting in sloppy steering. This new upgraded pin & bush solves all that with a sealed mini ball joint riding in a nylon cup. Unlike the standard part, it can smoothly rotate 360 degrees. Highly recommended.
