This is a replacement spider assembly. It includes rollers, pins, washers, and buttons.
The buttons are the large diameter type which allows them to ride on fresh surface area to tighten up slop from wear.
The buttons are made out of Dupont proprietary material for the longest service life possible!
The rollers are extremely heavy duty with a layered metal internal bushing. We found this new design to offer substantially longer service life compared to the stock fiber bushing.
