The Arrowmax AM-931014 7x1 O-rings are a practical maintenance item for on-road RC gear differentials. Designed for 1/12 and 1/10 scale cars, these rings help keep diff oil and grease in place for steady drivability.
Replacing worn seals with Arrowmax AM-931014 rings reduces the risk of oil weeping and contamination, which in turn protects gears and bearings and lowers service frequency.
These O-rings suit many 1/12 and 1/10 pancar differentials where a 7x1 seal is specified. They are useful for routine rebuilds, upgrades, or when prepping a car for a race day.
