      Diff oils

      RC diff oil in a wide range of weights for front, centre and rear diffs.

      RC diff oil is the silicone fluid inside a differential, and its weight sets how the diff behaves. Thicker oil tightens the diff for more traction on power, thinner frees it up for easier turning. We stock a broad range of weights for front, centre and rear diffs.Tune each diff separately to balance the car, and refresh the oil when handling changes. See all fluids in liquids, oils and glues.

      Frequent Questions & Answers
      What does diff oil do?

      Diff oil is the silicone fluid inside a differential. Its thickness controls how freely the wheels turn at different speeds, which affects traction and steering.

      How do I choose diff oil weight?

      Thicker oil tightens the diff for more forward traction, thinner oil frees the car up to turn more easily. Tune front, centre and rear separately to balance handling.

      How often should I change diff oil?

      Change it when the car feels different or after a rebuild. Racers refresh it regularly, while casual drivers can go longer between changes.

      What weight goes in front, centre and rear?

      It depends on the car and track, so check your setup sheet. As a rule, a thicker centre diff adds stability and a thinner front adds steering.
