Pan Car Diff Seal Kit 4.5X1 (10) - Arrowmax AM-931013  [AM-931013]

Service O-ring pack for pan car diffs

The Arrowmax AM-931013 Oring 4.5X1 (10) kit provides ten replacement O-rings meant for pan car gear differentials in RC models. This pack is useful for scheduled servicing, replacing aged seals, and making small spacing changes inside the diff assembly.

These O-rings match common pan car gear diff layouts in 1/12 and 1/10 scale vehicles and work well in low-profile diff housings. They serve as sealing elements or thin spacers to help keep oil contained and preserve gear mesh accuracy while running.

Fitting hints: inspect all mating surfaces for nicks, fit the ring without overstretching, and make sure it seats evenly in the groove. Replace worn rings in matched pairs or sets to keep diff behaviour even on both sides.

Tuning pointer: swapping to new O-rings can stop minor oil loss and maintain fluid placement under lateral load, which may lead to more predictable traction on pan car rigs.
