John Eckerton Exotek Arrma Grom/Losi NASCAR Aluminum Differential Outdrive Cups (2)

They won’t fit the Arrma V2 oiled filled diffs . These cups are longer and Only fit the original diffs . Don’t see how I can use them in stock racing ? Built a car just for play I was gonna use it for . Wish they would say that before purchase . Otherwise it’s a nice but overpriced . The Exotek CVDs will work with either diffs according to the email I received from Exotek . I have those on order from Amain .
