Team Associated RC8B3.1 Underdrive Differential Gear Set (42/12T)

Optional Team Associated RC8B3.1 Underdrive Differential Gear Set. This gear set for the RC8B3.1 and RC8B3.1e V3 differentials is great for low traction tracks. The underdrive gear set slows down the rear tire rotation compared to the front, making it more stable on low grip surfaces. Also fits the B4 series.
