Light weight, SUPER Hard Diff Rings for your Reflex Racing RX1180 Ultra Light Diff Kit or other ball differentials like the Kyosho which use round inner diameter rings. Precision ground and designed to last longer in between rebuilds. These rings are so hard that no coating is necessary to make them long lasting.
These rings are compatible with D Ring type diffs as well, but much like with our diff kit, we recommend to glue them to the diff half to ensure maximum performance.
