Upgrade to repleace the factory threaded bearing carrier which uses bronze bushings. This mod incorporates precision ball bearings and is a direct replacement to the original bearing carrier assembley. Nice upgrade to go along with the aluminum disc mod kit, or use by iteself with the original plastic disc assmebly. Benefits are increased disc revolutions by reducing the friction and direct contact between the bronze bushing and the base of the spinning disc.

Please indicate if you are planning to use this mod with the original plastic disc, or if you are using in conjunction with the aluminum disc upgrade.
