This O-ring pack is intended for the gear differential used in drift setups and fits at the axle mounting area to prevent differential oil leakage on RC-scale models. The kit contains 4 pcs to replace worn seals as part of routine servicing or when refreshing the sealing surfaces of a drift differential.
The part's purpose is sealing at the axle/differential interface to retain diff oil and protect internal lubrication, helping maintain consistent differential behaviour while drifting. Installation is typically carried out when the differential carrier is accessible during normal maintenance and does not require complex tools.
