Hot Bodies Cyclone Sport/Racing Diff Bearing Holder Aluminium Upgrade - CY-09/2 by 3Racing  [CY-09/2]

Diff bearing holder aluminium summary

This aluminium differential bearing holder is supplied as a replacement for Hot Bodies Cyclone Sport and Racing models. It acts as the bearing mount for the differential, offering a stiffer seating surface compared with some factory polymer holders to keep bearing alignment consistent under load.

With a firmer bearing seat you are likely to see less lateral movement in the diff assembly on the bench, which can help make drivetrain reactions more predictable when you change gearing or internal oils during setup sessions.

Fitting is straightforward differential maintenance: remove the diff from the gearbox, pull the bearings and original holder, press or fit bearings into the new aluminium holder ensuring full seating, and rebuild the diff. Standard RC hex drivers and hand tools are adequate for the task. Once installed, double-check bearing preload and ensure the reassembled drivetrain rotates freely with no binding.

Consider the holder as a precision tuning item that influences bearing alignment and diff behaviour; it supports consistent performance rather than creating dramatic speed improvements. Regular inspections of bearing fit and fastener torque will keep the diff working reliably over time.
