80A differential bushing kit for FC3S. Exact same design as the original 70A kit, but offered in a stiffer material and black colour. These bushings are a noticeable boost in stiffness over the 70A bushings I normally produce, and have a bit more stealthy look. I do not have experience running these, and cannot comment on their vibration levels etc.
See product description of the 70A kit for a more in depth description.
