TRF O-Rings 40° Gear-Diff., touring car parts

TRF O-Rings 40° Gear-Diff. are dedicated replacement parts for touring car oil-filled gear differentials. The set contains 4 blue ring-shaped O-Rings, arranged for direct use in differential service where this specific 40° specification is required. Their dedicated gear differential design focuses on minimal friction inside compatible oil-filled differential assemblies. In practice, that means the differential can work with less internal drag while transmitting drive through the drivetrain. The ring shape and smooth surface suit sealing and moving contact points inside the differential layout used on compatible touring car models. This is a targeted maintenance part rather than a universal ring set, so the stated compatibility with oil-filled gear differentials is the key fit detail. During workshop maintenance, the 4-piece pack supports a planned differential refresh or replacement of worn rings in an existing setup. The compact format also makes the set easy to keep alongside other touring car service parts for rebuilds, tuning sessions, and routine drivetrain upkeep on compatible RC cars.
